["TBMDA1 Modulated Wideband Driver Amplifier The TBMDA1 modulated wideband driver amplifier was developed to create a cost-effective signal source for interference immunity testing of electronic assemblies and products. It is designed to be controlled by the tracking generator output of spectrum analyzers. With its 22dB gain and a 1dB compression point of +22dBm, it can increase the output power of a tracking generator up to 150mW. The TBMDA1 is ideal for controlling Tekbox near-field probes to find the sensitive point of an electronic circuit or to generate electric fields up to 50V/m when controlling the Tekbox TEM Cell TBTC1, 25V/m when controlling the TBTC2 or 18V/m when controlling the TBTC3. The test signals for the immunity test can be CW, AM or PM. Therefore, the TBMDA1 offers a built-in modulation function to generate 1kHz AM or PM signals. In PM mode, the TBMDA1 can also generate a 217Hz signal with 12.5% ​​duty cycle to simulate mobile phone TDMA noise.
