Providing a low-cost signal source for resistance testing of electronic building blocks and products.
It operates in the frequency range of 1 GHz to 3 GHz and is designed to be driven by the output of a spectrum analyzer's tracking generator. The 1 dB compression point is an average of 350 mW. The saturation output is an average of 500 mW, amplifying the output of the tracking generator to drive the Tekbox near-field probe, allowing for the detection of sensitive areas in electronic circuits, or generating electric fields of up to 150 V/m CW and 80 V/m AM when driving the Tekbox TEM Cell TBTC 0, 80 V/m CW and 45 V/m AM when driving TBTC1, 40 V/m CW and 25 V/m AM when driving TBTC2, and 27 V/m CW and 15 V/m AM when driving TBTC3. The test signals for immunity testing can be CW, AM, or PM. The TBMDA7 has built-in modulation capabilities to generate 1 kHz AM or PM signals. In PM mode, the TBMDA7 can also generate a 217 Hz signal with a 12.5% duty cycle to simulate mobile phone TDMA noise.
