Details

The Tekbox TBMDA2 is a modulated wideband driver amplifier designed to be driven by the tracking generator output of spectrum analysers, but can also be used as a general-purpose gain block. This way you can create an inexpensive signal source (e.g. CW, AM, PM) for immunity testing of electronic building blocks. With its 1 dB compression point of +27 dBm, it can boost the output of a tracking generator up to 500 mW of power. This unit has a built-in modulation capability to generate 1 kHz of AM or PM signals. Furthermore, in PM mode, it can also generate a 217 Hz signal at 12.5% duty cycle in order to simulate mobile phone TDMA noise.

Both input and output are standard SMA connectors, rated at 50 Ω. The amp is powered by a mini-USB-B port on the back side of the device. Supplying through a USB 3.0 port or a charger rated 1 A or higher is recommended.

A nice addition to this device is the Tekbox EMCview PC application which supports immunity testing with a feature for automated tracking generator control, which significantly simplifies immunity testing, especially in case of repeated testing during validation of DUT modifications/improvements. The software is supported by Rigol, Siglent and R&S FPC/FPH series spectrum analysers.

Please be cautious not to directly hook up the output of the device directly to a spectrum analyser. Reference the maximum input ratings of your spectrum analyser and use an appropriate attenuator.
