The following readings are for a conventional base radio:
Current Stored Forward Power (Watts)
Forward power of the base radio at the last keyup
Current Stored Reflected Power (Watts)
Reflected power of the base radio at the last keyup
Current Stored VSWR
Voltage Standing Wave Ratio (VSWR) of the base
radio at the last keyup
5.10.7 Verifying Transmitter Performance (Digital Operation)
When and where to use:
Use this procedure to test the transmitter signaling patterns and verify the base radio transmitter meets the ASTRO
®
25 system standards by forcing the base radio to transmit a V.52 standard test pattern.
Procedure Steps
1
Connect to the base radios transceiver module in CSS through an Ethernet connection. See
Through an Ethernet Port Link, page 4-11
2
Select
Service → Test and Measurement Screen
from the menu. Select the
ASTRO Test Pattern
tab.
3
If the radio is not already in service mode, click
Change to Service Mode
.
Step result:
A confirmation dialog box appears.
4
Click
OK
.
Step result:
The base radio goes through a reset sequence to change modes. This takes a few minutes.
5
After the station resets, re-open the
Test and Measurement Screen
, as described in
.
