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.
The output of the TBMDA-BCI25 is quite tolerant to output mismatch, however open or shorted load is not recommended, as it potentially can cause damage to the output transistor. When driving near field probes, current probes or any load of unknown impedance, it is highly recommended to insert a ≥ 3 dB attenuator at the output of the amplifier in order to protect the output stage.
