Transmitter Power And Antenna Test; Procedure - GE MDS MDS 05-4558A01 Startup Manual

TRANSMITTER POWER & ANTENNA 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
the antenna system.
2. Place the transceiver into the Radio Test Mode.

The Test Mode has a 10-minute timer, after which it will
NOTE:
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 +28 dBm.

level during normal operation
4. Activate (key) the transmitter.
Main Menu>Maintenance/Tools>Radio Test>Test Mode>
TxKey> Enable
Use the spacebar to key and unkey the transmitter ON and OFF
(Enable/Disable).
5. Using the wattmeter, measure the forward and reflected power
into the antenna system and calculate the SWR. The ratio should
be less than 2:1. Higher levels may indicate a problem with the
antenna or feedline.
6. Turn off Test Mode at the Access Point and Remote radio.
