VHF power test
The VHF power test mode is used to measure the transmitted and the reflected power from
non-DSC VHF radios.
Use the same setup as for the testing of DSC radios (see page 12).
Select VHF power test on the test box and press OK.
Then, activate the transmitter and keep it activated while selecting Meas or Cont.
In the Meas (= Measure) mode, the test box will perform and display a single power
measurement and store it in the memory.
In the Cont (= continue) mode, the test box will continue taking measurements until pressing the
EXIT button stops it. Cont readings are not stored, but the feature can be used e.g. for
checking/adjusting the antenna.
Example of Printout from the Memory:
VHF # 1 Time/date: 08:18:16 / 21-11-2011
Power Measure Fwd: 20.3 Watt Rev: 0.1 Watt VSWR 1.16
VHF Frequency test
Use this setup to measure the frequency of VHF transmissions:
On the test box, select Frequency Counter and the preferred frequency range. Then press OK
and activate the transmitter. Select Meas or Cont to start measuring.
In the Meas (= measure) mode the test box will perform and display a single frequency
measurement and store it in the memory.
In the Cont (= continue) mode the test box will continue taking measurements until pressing the
EXIT button stops it. Cont readings are not stored, but the feature can be used e.g. for
checking/adjusting the antenna.
Example of Printout from the Memory:

Frequency measure: 156,300,128 Hz
