Description


The TEKBOX TBMDA1 modulated wideband driver amplifier is an inexpensive signal source for immunity testing of electronic circuits, products and systems. It is designed to be driven by the tracking generator output of spectrum analysers. With its gain of 22dB and 1dB compression point of +22dBm, it can boost the output power of a tracking generator up to 150mW. The TBMDA1 is ideal to drive TEKBOX near-field probes in order to find the sensitive spot of an electronic circuit or to create electric fields up to 50V/m when driving the TEKBOX TEM Cell TBTC1, 25V/m when driving the TBTC2 or 18V/m when driving the TBTC3. Test signals for immunity testing can be CW, AM or PM. Consequently, the TBMDA1 provides built in modulation capability to generate 1kHz AM or PM signals. In PM mode, the TBMDA1 can also generate a 217Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.
