TBMDA1
Modulated Wideband Driver Amplifier
The Tekbox TBMDA1 is a modulated wideband driver amplifier designed to act as an inexpensive signal source for immunity testing of electronic circuits and products. It is intended to be driven by the tracking generator output of a spectrum analyzer and provides significant gain to boost low-power RF signals to usable test levels. With its built-in modulation features, it can generate CW, AM, and PM test signals for a wide range of EMC and RF testing applications.
