- CW amplifier (modulation of)
- 1 kHz, 80% AM modulation
- 1 kHz, 50% duty cycle pulse modulation
- 217 Hz, 12.5% duty cycle pulse modulation
The TBMDA1 modulated broadband amplifier is designed to create an inexpensive signal source for immunity testing of electronic building blocks and products.
It is designed to be driven by the tracking generator output from spectrum analyzers.
With its 22dB gain and 1dB compression point of +22dBm, it can increase the output power of a tracking generator up to 150mW.
The TBMDA1 is ideal for driving Tekbox near field probes to find the sensitive spot in an electronic circuit or to create electric fields of up to 50V/m when running the Tekbox TEM Cell TBTC1, 25V/m when running the TBTC2 or 18V/m when you are running 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, TBMDA1 can also generate a 217Hz signal with 12.5% duty cycle to simulate TDMA noise from mobile phones.
