- 217 Hz, 12.5% duty cycle pulse modulation
The TBMDA4B modulated wideband power 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 an input power range of -20 dBm...-10 dBm, it can increase the output power of a tracking generator by up to 5W. With a frequency range of 100 kHz to 75 MHz, it is an ideal complement to the TBMDA3, which covers 10 MHz to 1 GHz.
TBMDA4B is ideal for driving Tekbox near field probes to find the sensitive spot in an electronic circuit or to create electric fields up to 550V/m when running Tekbox TEM Cell TBTC0, 300V/m when running TBTC1, 150V/m when running run TBTC2 or 100V/m when running TBTC3. Test signals for immunity testing can be CW, AM or PM modulated. Consequently, the TBMDA4B provides built-in modulation capability to generate 1 kHz AM or PM signals. In PM mode, the TBMDA4B can also generate a 217 Hz signal with 12.5% duty cycle to simulate TDMA noise from mobile phones.
