RF pulse monitor
This is a monitor signal output. The voltage present at this point is 40 dB less (a factor of
100) than the voltage present on the High power RF pulse output. Connect this to an
oscilloscope with a 50 Ω terminated input.
Diplexer output to receiver
This is the output of the internal signal diplexer. Connect this to one of the receiver
inputs to do pulse-echo mode operation.
