The TBMDA5 modulated amplifier provides the necessary power, bandwidth and modulation for conducted immunity tests with CDNs in the frequency range from 150 kHz to 400 MHz. It is designed to be driven by the tracking generator output from spectrum analyzers.
With a 1 dB compression point of up to 2.5W in the frequency range 150 kHz to 400 MHz, it can generate test levels class 1 and class 2 according to ISO / EN 61000-4-6. A built-in AM modulator enables the use of tracking generators as a signal source.
The TBMDA5 has sufficient gain to achieve the maximum output power of 0 dBm provided by a spectrum analyzer tracking generator.
In addition to 1 kHz, 80% AM, the TBMDA5 has built-in modulation capability to generate 1 kHz, 50% duty cycle PM signals. In PM mode, the TBMDA5 can also generate a 217 Hz signal with a 12.5% duty cycle to simulate mobile phone TDMA noise.
