The TBMDA-BCI25 modulated amplifier provides the necessary bandwidth and modulation for conducted immunity testing using BCI probes per ISO 11452-4 in the frequency range from 1 MHz to 400 MHz. It is designed to be driven by signal generators or by tracking generators of spectrum analyzers. With a 1 dB compression point of up to 30 W in the frequency range 1 MHz to 400 MHz it can generate test levels up to 400mA. A built in AM / PM – modulator enables use of tracking generators as signal source. The TBMDA-BCI25 has sufficient gain to achieve maximum output power with 0 dBm provided by a spectrum analyzer tracking generator.
Besides 1 kHz, 80% AM, the TBMDA-BCI25 provides built in modulation capability to generate 1 kHz, 50% duty cycle PM signals. In PM mode, the TBMDA-BCI25 can also generate a 217 Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.
