The TBMDA-BCI25 modulated amplifier provides the necessary bandwidth and modulation for performed immunity tests with BCI probes according to ISO 11452-4 in the frequency range from 1 MHz to 400 MHz. It is designed to be driven by signal generators or by trace 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 the use of tracking generators as a signal source. The TBMDA-BCI25 has sufficient gain to achieve a maximum output power of 0 dBm provided by a spectrum analyzer tracking generator.
In addition to 1 kHz, 80% AM, the TBMDA-BCI25 has 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 to simulate TDMA noise from mobile phones.
