INSTALLATION
To install the AV-201 orAV-601 simply connect coaxial cable directed to the antenna connector marked “ANT”,and
The cable coming from the transmitter or from the linear amplifier to the connector marked “TX”
AV-201/orAV-601 is ready to operate.
POWER MEASUREMENTS
1 Select the RANGE (3) switch on the end-scale position value as to the power of the unit
2 Select the FUNCTION (4) switch in the power position
3 Select the POWER switch the FWD position to measure the direct power(from the radio to antenna)
or REF position to measure the reflected power(from antenna to the radio)
4 Select the power value can be read on the corresponding scale.
SWR MEASUREMENTS
1 Select the RANGE (3) switch on the end-scale position value as to the power of the unit.
2 Select the FUNCTION (4) switch in the CALposition .
3 Let the radio transmit and adjust the instrument by turning the CAL knob, position the end-scale index in the
CAL position.
4 Select the FUNCTION (4) switch in the SWR position
5 Read the SWR value in the above scale.
