TBMDA2 Modulated Wideband Driver Amplifier
The modulated wideband driver amplifier TBMDA2 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 1dB compression point of +27dBm, it can increase the output power of a tracking generator up to 500mW. The TBMDA2 is ideal for controlling Tekbox near-field probes, to find the sensitive point of an electronic circuit or to generate electric fields up to 170V/m when controlling the Tekbox TEM Cell TBTC0, 100V/m when controlling the TBTC1, 50V/ m when controlling the TBTC2 or 30V/m when controlling the TBTC3. The test signals for the immunity test can be CW, AM or PM. The TBMDA2 therefore offers a built-in modulation option for generating 1 kHz AM or PM signals. In PM mode, the TBMDA2 can also generate a 217 Hz signal with 12.5% duty cycle to simulate cell phone TDMA noise.
