Monitoring The Transmitter Metering Points; Verifying Transmitter Performance (Digital Operation) - Motorola ASTRO 25 GTR 8000 Manual

b At the confirmation screen, click OK.
The base radio halts activity in the current mode and switches operation to the requested
mode.

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
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.
5 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.
Current Measured Forward Power (Watts)
Current Measured Reflected Power (Watts)
Current Measured VSWR
The following readings are for a conventional base radio:
Current Stored Forward Power (Watts)
Current Stored Reflected Power (Watts)
Current Stored VSWR

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
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
2 From the menu, select Service → Test And Measurement Screen. Select the ASTRO Test
Pattern tab.
