TekBox TBMDA-CDN25 Modulated Wideband Power Amplifier

The TBMDA-CDN25 modulated amplifier provides the necessary power, bandwidth and modulation for conducted immunity testing using CDNs and BCI probes in the frequency range from 100 kHz to 250 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 25 W in the frequency range 100 kHz to 250 MHz it can generate test levels class 1, class 2, class 3 and class X according to ISO / EN 61000-4-6. A built in AM / PM – modulator enables use of tracking generators as signal source. The TBMDA-CDN25 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-CDN25 provides built in modulation capability to generate 1 kHz, 50% duty cycle PM signals. In PM mode, the TBMDA-CDN25 can also generate a 217 Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.
