Monitoring the Transmitter Metering Points
Procedure:
1
Connect to the transceiver module in Configuration/Service Software (CSS) through an Ethernet
connection. See
Connecting Through an Ethernet Port Link on page 140
2
From the menu, select
Service
→
Metering Screens
.
The
Metering Screen
dialog box appears.
3
Select the
Transmitter
tab.
4
Click
Transmitter Test
to briefly key up the transmitter.
The status bar on the window confirms if the transmitter is operating properly or if it has failed.

The
Current
column displays the values read for the following:
NOTICE:
When the base radio is transmitting, the
VSWR
field on the screen displays a
value of 1 or greater; when the base radio is not keyed, 1 is displayed.
Item
Measure
Current Measured Forward Power (Watts)
Forward power of the base radio
Current Measured Reflected Power (Watts)
Reflected power of the base radio
Current Measured VSWR
Voltage Standing Wave Ratio (VSWR) of the
base radio
The following readings are for a conventional base radio:
Current Stored Forward Power (Watts)
Forward power of the base radio at the last
key up
Current Stored Reflected Power (Watts)
Reflected power of the base radio at the last
key up
Current Stored VSWR
VSWR of the base radio at the last key up

Verifying Transmitter Performance (Digital Operation)
When and where to use:
Use this procedure to test the transmitter signaling patterns and verify that
the base radio transmitter meets the ASTRO
®
25 system standards by forcing the base radio to
transmit a V.52 standard test pattern.
Procedure:
1
Connect to the transceiver module in Configuration/Service Software (CSS) through an Ethernet
connection. See
Connecting Through an Ethernet Port Link on page 140
