TekBox TBMDA-BCI25 Modulated Wideband Power Amplifier
The TekBox TBMDA-BCI25 is a modulated amplifier that offers the necessary bandwidth and modulation for conducted immunity testing with BCI probes per ISO 11452-4 in a frequency range 1 to 400 MHz. The amplifier 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 range 1...400 MHz it can generate test levels up to 400 mA. 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 TekBox TBMDA-BCI25 also provides built in modulation capability to generate PM signals with 1 kHz and 50% duty cycle. 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.
