Focus Microwaves - Low Frequency Tuners
The low frequency tuners are a unique product technology using MPT algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors.
The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.
A multi-band, electro-mechanical programmable impedance tuner for the frequency range between 10 and 200 MHz uses cascades of three or more continuously variable mechanical capacitors interconnected with sets of low loss flexible or semi-rigid cables; for each frequency band a different set of cables and capacitors are used. The cables and/or variable capacitors inside each tuning block are switchable manually or remotely. Multi-section variable capacitors are also used. Instantaneous impedance tuning is effectuated by changing the state of the capacitors using electrical stepper motors. The tuner is calibrated using a vector network analyzer and the data are saved in the memory of the control computer, which then allows tuning to any user defined impedance within the tuning range. Reflection factor values between O and higher than 0.9 can be obtained using this tuner at all frequency bands.

EMC test equipment to evaluate the resistibility of electronic devices and components when energy charged on a human body or object is discharged to the electronic devices and components. NoiseKen brand ESD simulator is available to see malfunctions or function declines of electronic equipment for appropriate evaluations compliant with IEC61000-4-2 Ed.2 Test Standard & ISO 10605 ed.2 standards.
The ESS-S3011A features a function which enables the user to pre-program test settings to minimize setup errors as well as having the unit be incorporated into a remote or autonomous testing setup. Another feature that sets apart NoiseKen ESD guns to that of competitors is the discharging gun separation design which helps achieve the lightweight.
For conventional ESD guns, that have generators that are inseparable from the gun, you may experience having to replace the whole unit even only when certain parts of the unit are broken. However, with the NoiseKen’s separation design, replacement parts can be minimized to lower the running cost.
