Place in Standby, remove 30dB attenuator and connect the power meter directly to the power meter adaptor
plate. Set dB REL to -16.8dB on the power meter, this is the loss of the waveguide adaptor only.
Run through the remote stations for F0 to F3 in the ASI and log the standby results in section 4.3 of the build
record.
The suppression is the difference between the high power output and standby. For example +20dB high
power output and -25dB standby power would be a suppression of 45dB. This is the final calculation for
section 4.3 of the build record.
