Tekbox TBMDA-BCI25 modulated power amplifier
Details
The Tekbox TBMDA-BCI25 modulated power amplifier provides the necessary modulation and bandwidth for accurate immunity testing (per ISO 11452-4) with BCI probes. Designed to be driven by a signal generator, a tracking generator (through the internal AM / PM - modulator) or a spectrum analyser, it can generate test levels up to 400mA in the frequency range of 1 MHz to 400 MHz.
Furthermore, it has sufficient gain to achieve maximum output power with 0 dBm provided by a spectrum analyser tracking generator. In PM mode, the amplifier can also generate a 217 Hz signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.
