Device in the setup
Task of the R&S
OSP switch unit
Signal generator
Switching the output of one generator to one out of three power amplifiers, for
example:
●
One amplifier for conducted testing with BCI (Bulk Current Injection) clamp
or CDN (Coupling / Decoupling Network)
●
Two amplifiers for radiated testing with log-periodic and horn antennas
Power amplifiers
Switching amplifier outputs to the required transducers in a semi-anechoic cham-
ber
Power meter
●
Switching of forward or reverse power from each of the three amplifiers to
the monitoring power meter
●
Switching the conducted transducer's output to the power meter for calibra-
tion
Interlock
●
Monitoring the door contact of the semi-anechoic chamber
●
Switching the power amplifier to standby, it the door is open
●
Optionally interrupting the signal path from signal generator to power ampli-
fiers, if the amplifiers have no interlock security loop see
●
Displaying the interlock state in a remote location, for example, at the front
side of the test rack
Antenna mast
