A single-polarization 160-Gb/s (80-Gbaud) electronically time-division-multiplexed (ETDM) quadrature phase-shift-keyed (QPSK) signal is generated and coherently detected using two 45-GHz-bandwidth oscilloscope prototypes and offline processing.

Much like driving from one point to another in a big city, routing an electrical signal between a test instrument and a device under test can require navigating a complex network of interconnected relays, wiring and interfaces. Instead of right and left turns, the ATE software engineer must determine the correct position setting of multiple relays to establish the desired route. 

In this training, you'll learn how Switch Path Manager (SPM) signal routing software accelerates the software development effort of Automated Test Systems, considerably reducing the number of lines of code required to route test instrumentation to the device to be tested.

Test chambers that never compromise on performance, safety, or environmental responsibility

Not all chambers offer the same performance or quality. All reverberation, fully and semi-anechoic chambers provided by AR RF/Microwave Instrumentation, offer customers the highest level of performance, quality, and support. One unique advantage is the pan shield design, which allows for premium performance and seamless construction over older designs techniques, such as wood core shielded chambers. The pan-type shield's baseline performance is far more reliable and exceeds 100 dBA level of attenuation up to 40 GHz without any modifications or add-ons. This performance provides an excellent testing environment for your testing needs.

Debugging PHY Layer Link Communication Learning Lab

In this session (Part 4), we review Automotive Ethernet link communication and explore how to debug and troubleshoot these links using an oscilloscope during an interactive session with live signals. We will look at both the physical and protocol layers during this Learning Lab webinar.

Topics to be covered in this webinar:

5G deployments are now underway across the globe but are merely the first steps in a multi-year journey for the mobile industry. Many practical challenges still remain, not least of which is the challenge of cost-effectively deploying 5G Radio Access Networks (RANs) at scale and assuring the performance of supported 5G services.

The 5G RAN architecture provides an open, virtual, packet-based network that extendsfrom the core to the radio antenna. The virtual architecture of 5G RAN with network slicing and new functional elements, such as the Central Unit (CU) and Distributed Unit (DU), enables multiple demanding services to share the same infrastructure without compromising on their specific performance requirements. Virtual, packet-based RANs also enable network sharing over open interfaces as well as multi-vendor implementations, both of which are important to the 5G business case.

Hardware appliances, such as the Remote Radio Head and Baseband Unit of 4G LTE are now replaced with virtual software running on whitebox or Commercial Off-The-Shelf (COTS) hardware. In 5G, the Baseband Unit is split into two new functions, namely the CU and DU. Both these functions can be located either close to the 5G core or close to the Radio Unit (RU) to meet latency and backhaul requirements. This leads to a much more dynamic fronthaul, midhaul and backhaul network, which is now collectively referred to as the 5G cross-haul or “X-haul” network.

It also means that the traditional aggregation architecture where higher capacity is required closer to the core is no longer the norm. As cloud computing and other real-time services move closer to the edge of the network, more traffic is likely to remain close to the subscriber requiring higher capacity X-haul networks with 10G, 25G and even 100G Ethernet connectivity.

We experimentally demonstrate 8 dB of mode-equalized distributed Raman gain using a backward pumping scheme. The equivalent noise figure of the amplifier is -1.5 dB, and the amplifier was successfully employed to demonstrate 6-channel mode-multiplexed MIMO transmission over 137-km few-mode fiber.

For the most efficient validation, get the most analog channels and longest memory to capture your entire power sequence.

1. Start with WaveRunner 8000HD’s 8 analog channels, 16 with our OscilloSYNC™ option.
2. Add MSO capability for 16 digital lines, no sacrifice of analog channels.
3. Use 5 Gpts memory to capture the entire power on/off sequence.
4. Use automated measurements with Pass/Fail testing to validate timing over multiple acquisitions.

Watch the video to see how.

Selecting the right cable is crucial for both Microwave and mmWave applications. Indeed, measurements are not accurate nor reliable unless appropriate cables are used. This video outlines how to select the most appropriate cable for any given purpose.

Power Electronics are the most critical components in a large number of applications; including power generation and operational equipment. Power Electronics module manufacturers invest millions of dollars to make these devices as effcient as possible, aiming primarily to reduce waste heat. However, even with effciency gains at the module level, overall waste heat is rising across the industry due to more system and user driven functional requirements. Increased system capability leads to higher power densities and more waste heat! Selecting off the shelf thermal solutions is no longer a viable option for applications that are pushing the envelope on power and operating effciency.

Investing in an optimal thermal solution can be the design change with the largest payback potential in a high power system. If properly designed, the thermal management system should not only meet performance requirements, but do so while minimizing energy usage. This eBook provides a guide for designers looking to expand the operating limits of traditional air and liquid cooled thermal solutions.

Power electronics designs have inherent measurement challenges. This has led to development of many specialized high and low voltage single-ended and differential probes to meet the specific needs of this market. However, proper probe selection and use is critical for operator, equipment and DUT safety and also has a large influence on the accuracy of the measurement.

Join Teledyne LeCroy for this two-part webinar series as we provide tips to overcome these questions.

In Part 1 we review the different HV rated probe specifications and topologies and explain what measurement each probe topology is ideally suited for. Register here

Objects with unique 3D aspects can make identifying surface defects with standard machine vision configurations more difficult. One solution to achieve feature-appropriate surface contrast is Photometric Stereo.

Machine Vision Challenge: Cement Board Inspection

A customer inspecting 4 ft. by 10 ft. white fiber-cement boards required a lighting solution to highlight small 5cm long and 1mm thick surface scratches and defects. They also identified significant surface concavity created during the manufacturing process on some of the 2cm thick boards. As a result, they required the flexible lighting solution to also assist their efforts to develop an identification and grading system to pass/fail board concavity.

The cement boards were inspected in motion, running 1 foot/second through an enclosed tunnel. The inspection setup required a low-angle, narrow beam throw for uniform illumination across the full surface of the board to identify the scratches. The tunnel setup also required the use of longer lights for full board coverage and to facilitate installation.

An additional inspection using the same area-scan camera, but with bright field oriented lighting, necessitated the two lighting orientations be independently controlled with an on/off trigger. The customer contacted Control System Integrators (CSI), Inc. to configure a lighting solution for this inspection challenge.

Ai Solution: High Intensity Bar Lights

Via Ai’s Distribution Partner, Kendall Electric, CSI, Inc. reached out to Advanced illumination to provide a dark field lighting solution for their customer. To match the size and uniformity needs, Ai suggested the LL174 High Intensity Bar Lights with a diffuse light conditioning.

These lights are highly customizable, each available in the 24” length demanded of the application. The configurable control options also allowed for the use of the iCS 3 Inline Cable Controller to enable constant or strobed power to the light. The longer length and controller options met the customer’s initial requirements to fit within the existing machine vision setup constraints.

The cable design for a automated test system is critical for repeatability and accuracy, it needs care and expertise. Depending on the application, a test engineer needs to consider test specifications, including voltage, current, temperature, insertion losses, and more. Unless the test engineer is an expert on cabling, researching wires and connectors can be a daunting task.

There are times when a standard cable assembly is not suitable, and there is a need for custom connectors and wire types or specific harness wiring. Our free online Cable Design Tool (CDT) is a simple and efficient way of creating these custom cabling solutions.

Cable flexibility is important for stable measurement and wiring efficiency between the measuring equipment and device under test. Junkosha provides flexible and low resilience coaxial cables which improve workability with complex wiring and reduces the risk of damage to the instruments and DUT.

Many questions have obvious answers if we understand just a little bit about transmission lines and what the oscilloscope actually measures:

Topics to be covered in this webinar:

• Is it really true that the longer the cable, the longer the RC charging and the longer the rise time?
• Does this mean only short cables can offer high bandwidth?
• When should you use a 50 Ω input and when a 1 MΩ input to the scope?
• Why do I measure a rise time of 150 ns for the compensation signal on the front of the scope and others report it as 5 ns rise time?

Who should attend? Any engineer who wants a practical understanding of transmission lines and why this is so important in any oscilloscope measurement.

You’ve got a scope, now how do you get the most out of it without spending a lot of money?

In this free webinar from Teledyne LeCroy, Eric Bogatin will show you the right way you can do five common SI and PI measurements with a budget scope and some simple probes you probably already have around. We’ll look at some of the common artifacts to avoid so you can get meaningful measurements.

Topics to be covered in this webinar:

All electronics dissipate waste heat. In typical high-power electronics cabinets this waste heat can become significant, in the range of 100’s to 1,000’s of Watts. At these levels dissipating the waste heat becomes a critical design issue. Most cabinets that operate in controlled indoor environments use fan filter systems, which duct ambient air through the cabinet, because they are the most eective and ecient way of dissipating the waste heat load. This is also feasible for some outdoor applications assuming rain guards and filters are used.

However, in many applications such as dirty / dusty environments, hose down / wash down facilities in the food industry, harsh outdoor applications, and many others it is not possible or advisable to allow ambient air to flow through and cool the sensitive and expensive components inside your enclosure. The best way to protect electronics is to use a sealed cabinet that does not allow any contaminated ambient air, even filtered air, from entering the cabinet. This is where sealed air-to-air heat exchangers, or sealed enclosure coolers, become an invaluable part of the overall system.

For ten years, I’ve had the honor of presenting a tutorial session at the IEEE EMC Symposium. I’m usually positioned right after Bruce Archambeault. This means I get to listen to Bruce talk about inductance. While I think of myself as a bit of an expert on inductance, I always learn something new when I listen to Bruce.

One example he shows, using a simulation of where current flows, will completely recalibrate your intuition if you have never thought about this question. This example stuck with me for more than a dozen years since I originally saw it. Recently, I had a chance to play with the Teledyne LeCroy CP031A current probe used with our scopes and I realized this classic simulation example could be demonstrated with a simple measurement.

The oscilloscope has been a primary tool for electronic design engineers since the invention of that instrument, many years ago. The first decades of oscilloscopes were “analog” in nature.

One of the most basic things to know when using any probe is “what is the maximum voltage the device can safely measure?” The answer isn’t as straightforward as you might imagine, it requires understanding several key probe specifications as well as the nature of your signal.

Single-ended Range

Everyone is pretty familiar with single-ended range: that's the maximum safe voltage input to ground, shown in Figure 1. Ground is directly tied to oscilloscope ground, which is tied to building ground. Therefore, when measuring voltage within this range using a single-ended probe, the ground connection cannot be a floating voltage, or you could damage the probe, the DUT, the oscilloscope...maybe yourself, as well. Single-ended voltage must be a grounded voltage on your board or something that could be tied to ground.

Dynamic Range and Maximum Non-destruct Input Voltage

ADVANCED COOLING TECHNOLOGIES, INC. (ACT) HAS WORKED EXTENSIVELY ON HEAT PIPE PRODUCT RELIABILITY. This guide provides information for designing, modeling, and practical reliability surrounding copper/water heat pipes.

A heat pipe is a two phase heat transfer device with very high “effective” thermal conductivity. It is a vacuum tight device consisting of an envelope, a working fluid, and a wick structure. As shown below, the heat input vaporizes the liquid working fluid inside the wick in the evaporator section. The saturated vapor, carrying the latent heat of vaporization, flows towards the colder condenser section. In the condenser, the vapor condenses and gives up its latent heat. The condensed liquid returns to the evaporator through the wick structure by capillary action. The phase change processes and two phase flow circulation continue as long as the temperature gradient between the evaporator and condenser are maintained.

Enhanced Sample Rate, combined with the low-noise system architecture and the tailored brick-wall frequency response in the HDO4000A, HDO6000A, HDO8000A and MDA800A series oscilloscopes dramatically improves the measurement precision when the input frequency signals are very high frequency, such as a high-frequency sine wave or fast edge.

SD-WAN was first introduced to provide a reliable and cost-effective backup to MPLS-based enterprise WAN connectivity. As IP and Internet networks have become more reliable, along with the growth in adoption of cloud services, SD-WAN has evolved and is replacing branch office routers as the preferred WAN connectivity solution.

According to Gartner, 60% of enterprises will have implemented SD-WAN by 2024 compared to just 30% today. At least 30% of enterprise locations will only have Internet WAN connectivity, which is twice the current number. The impact of SD-WAN on the WAN infrastructure market is also clear with Gartner expecting a Compound Annual Growth Rate (CAGR) of -3.1% from 2017 to 2024 as cheaper SD-WAN solutions replace more expensive branch office routers

Nevertheless, one should not make the mistake of thinking that SD-WAN is less complex or intelligent. Quite the contrary in fact. The latest generation of SD-WAN solutions are expected to be application-aware and capable of determining the optimal path through the WAN in real-time on a per application basis. This includes cloud services with direct offload from the branch to co-located cloud edge services. In addition, sophisticated security capabilities are provided to support Zero Trust Network (ZTNA) and/or Secure Access Service Edge (SASE) concepts.

The sophistication of modern SD-WAN solutions allows a true de-coupling of WAN connectivity from the underlying transport mechanism, which is predominantly Ethernet based. It also means that there is little insight into the data transport layer, only to the tunneled SD-WAN connections that are supported. As data consumption continues to grow and more sophisticated and demanding Internet-based services contend for public Internet resources, the underlying data transport layer networks supporting SD-WAN are becoming more dynamic and unpredictable. Multiple choices can be available, such as fixed broadband access over copper or fiber, Fixed Wireless Access (FWA) or 5G mobile broadband, but when should one choose these options, and can one be sure that the current measured performance will be maintained?

We didn’t expect to have DC outputs be so noisy! Is it really the circuit that is a problem or is our scope and/or probe causing signal integrity issues? We even tried changing output capacitors to improve the performance, but why are we seeing 2X greater output noise than we expected?

In this session we review which probes are best for your application and how best to connect to your oscilloscope to minimize RF pick up.

Topics to be included:

Heat pipes have been used for spacecraft thermal control for decades; however, the technology is continuously evolving. Heat Pipes are often selected due to their combination of thermal performance, low mass, and high reliability. This webinar will explore several variants including ammonia Constant Conductance Heat Pipes (CCHPs), Variable Conductance Heat Pipes (VCHPs), Loop Heat Pipes (LHPs) and Space Copper-Water Heat Pipes (SCWHPs). Each technology option provides a unique benefit for the spacecraft architecture.

This webinar will dive into details to help aerospace engineers select and apply the appropriate technology- exploring considerations such as including heat flux, transport distances, geometry and mass. Our subject experts will also be available after the webinar for specific questions on your application.

We are all pretty good at setting a time window for our capture. But, what about the waveform memory that is used for the capture? How does this interact with the sample rate as we vary the time window? Can we segment the timebase to capture only the important circuit behaviors?

Topics to be included:

• Timebase, memory length and sampling rate – how do these impact our results?
• Timebase delay – pre- and post-trigger location
• Sequential timebase – capturing “just the facts”
• Scope preferences we forget are available

How to Efficiently Debug Embedded Systems with Your Oscilloscope

Join Teledyne LeCroy for this 3-part webinar series on how to efficiently and accurately debug embedded systems with your oscilloscope. The goal of this series is to improve your knowledge and efficiency in validating and troubleshooting the interactions of analog, digital, serial data, and sensor signals in embedded designs.

Fundamentals of Signal Display and Measurements

In this session (Part 1), we will discuss the various signal display and measurement tools available in oscilloscopes and how to avoid the traps and pitfalls that lead to inaccurate or inefficient measurements. We will also review how to extract circuit details from both short and long record acquisitions to aid in debugging of embedded designs.

Topics to be included:

• Improving measurements with multi-grids
• Analytical waveform views
• Using measurement parameters effectively
• Best uses of statistical data and views
• Pass/Fail parameter testing

Who should attend? Design Engineers and Technicians looking to improve skills and efficiency in using an oscilloscope to both validate and troubleshoot the circuit performance of embedded designs.

We experimentally demonstrate multiple-input-multiple-output transmission of a combined 3-space-, and 2-polarization-, and 5-wavelength-division multiplex in a 3-core microstructured fiber over 4200 km. This is the record transmission distance for spatial-division multiplexing in a fiber.

In this video, we show how you can use scripts to exchange data in real time between Teledyne LeCroy MAUI Studio oscilloscope software and third-party applications like MATLAB, Excel and LabVIEW. For additional information visit, teledynelecroy.com/mauistudio.

Networking devices supporting 800Gbps Ethernet are now being developed, with some industry analysts predicting the next tech cycle of 1.6Tbps (Terabits per second) could arrive as early as 2024.

But the devil's in the details - and there are a lot of details.

Xena's new White Paper examines the technical options and challenges of bringing terabit Ethernet to life. Learn how faster electrical lane speeds, new modulation schemes and the need for better Forward Error Correction (FEC) mechanisms are playing a key role, as well as why you'll need to test changes to the Ethernet physical layer and transceiver form factors.

We explore in detail the relationship between discrete-frequency responses connected with sparameters and the implied continuous time response. This is done in both the frequency- and time-domain to develop the proper insight and explore issues with real time-domain responses, time-aliasing, causality, interpolation and re-sampling of discrete-frequency data. Using the insight gained, we identify the conditions for sufficiency of sampling and the side-effects of the invariable practical conditions when these side-effects cannot be completely dispelled. This paper is especially useful for understanding issues involved in direct application of sparameters in linear simulations, like those used in virtual probing applications in scopes.

A Time Domain Reflectometer (TDR) displays the instantaneous single-ended or differential impedance profiles of an interconnect and the location of discontinuities. While this is valuable information, there is additional information we can extract by expanding to multiple ports and looking at not just the differential impedance, but also the common impedance and even the location of crosstalk and mode conversion.

Join Eric Bogatin and Teledyne LeCroy as we introduce the value of looking at multi-port and mixed-mode TDR and impedance measurements, the best measurement practices and how to analyze the results.

Topics to be covered in this webinar:

• Converting frequency domain into the time domain
• Impedance profiles and interconnect structures
• Measuring near- and far-end crosstalk
• Identifying the location of crosstalk
• Features that can cause mode conversion
• Three important consistency tests to always consider

Who should attend? Engineers who need to characterize the electrical properties of interconnects, or currently use TDR measurements.

What attendees will learn? How to use TDR measurements to interpret interconnect electrical features.
