Power Measurement

For measuring the output power on

AIS channel 1 or 2

, use the setup below and wait for the

automatic transmission from the AIS transponder.

The test box must receive a trigger signal on RF IN in order to start the power measurement. If
the test box waits for more than 20 seconds, the trigger signal level might be too low. Then
connect a VHF antenna to RF IN (dotted figure):

Alternatively, use this setup:
