Meatest - M632 Real-Resistance Decade Box
-
Real resistors switched by relays
-
Custom units and time sequences
-
No residual resistance
-
20 ppm accuracy
-
Six different languages
Resistance decade box with 1 Ω - 1.2 MΩ range, high accuracy and temperature stability. Best resolution 10 μΩ, RTD temperature sensor simulation feature.
M632 is 20 ppm reference instrument for calibration laboratories and flagship of Meatest's resistance calibration. Containing some of the most stable (and expensive) foil resistors available, the M632 has just 1 ppm/°C temperature coefficient. Floating output terminals of M6xx decades allow for AC measurements as well, see datasheet for typical frequency responses.

User comfort
M6xx series was made to make resistance calibration as easy as it gets. Large LCD shows all related parameters including total accuracy. And there is no residual resistance or hidden absolute error so you don't have to calculate it by yourself, accuracy you see is what you get. And that's not the only thing that firmware sorts out for you. Would you like the resistance shown in temperature units? Distance? Force? RTD and user function will do this for you. Complete recalibration? Ten minutes and off you go.
Connectivity
All decades' functions can be remotely controlled via RS232, USB, LAN or GPIB interface. This way you can introduce calibration/test stage directly into production line of any resistance based sensor and reduce time required for final quality tests dramatically.

The CORTEX Best Source Selector (BSS) is the ultimate choice for real-time telemetry source selection. It’s the go-to tool for pinpointing the best Telemetry source among multiple antennas tracking the same airframe across various channels.
The Best Source Selector streamlines the selection process by automatically choosing the top Telemetry stream, even from up to 16 sources or more, using a combination of signal quality metrics and other criteria. With its extensive capabilities in aligning paths and compensating for delays, the CORTEX Best Source Selector ensures optimal source selection, no matter where the antennas are located or what kind of range infrastructure you’re working with.

NoiseKen simulators to reproduce fast rise-up noises which are generated when switching ON / OFF electric current on the inductive load.
Since the pulse includes broadband frequency and its rise-up time is fast at 3ns or less, it can make the noise coupling dense and effective to reproduce the malfunctions of electronics equipment under the test.
It can realize performance evaluation of electronics equipment's upon reproduction of line noises which are intruded to the power supply lines or induced noises onto the telecommunication lines.
