TRANSMITTER POWER AND ANTENNA

SWR TEST

The following procedure may be used to measure the transmitter’s RF

power output and SWR “match” of the antenna system. A directional

wattmeter is required for the test, such as a Bird Model 43, with an

appropriate element installed.

Before you start, keep in mind that using the Test Mode will disrupt

network operation.

Procedure

1. Connect a directional wattmeter between the ANTENNA port and

the antenna system.

2. Place the transceiver into the Radio Test Mode.

Main Menu>Maintenance/Tools Menu>Radio Test>Test Mode>Y>ON

NOTE: The Test Mode has a 10-minute timer, after which it will

return the transceiver to normal operation. The Test Mode can also

be terminated manually, via the menu.

3. Set the transmitter RF output power to 30 dBm.

Tx Power Output

NOTE: The Test Mode RF power setting will not affect the output

level during normal operation.

4. Turn on (key) the transmitter.

User the spacebar to key and unkey the transmitter ON and OFF.

(Enable/Disable)

5. Measure the forward and reﬂected power into the antenna system

and calculate the SWR. The ratio should be less than 2:1. The

power output level should agree with the programmed value set in

Step 3.
