MTR3000 Programming and Tuning: Tuning Setup (Wireline) 13-5
13.4.1.2 Verification or Test Procedure for High Power
1. Power the Station from either an AC or DC source.
2. Connect the radio’s Tx antenna port, through an attenuation pad and calibrate the path loss,
to the Communication Analyzer.
3. Via the CPS, program the radio with all user frequencies supported by the base station/
repeater in analog mode.
4. Enter the test frequency into the Communication Analyzer and set the analyzer in power
meter mode.
5. Connect a Mic to the RJ45 connector at the front panel.
6. Press the PTT button on the Mic.
7. Measure the transmit power.
8. If the measured transmit power is not within the original MTR2000 specifications range, the
PA must be replaced as it cannot be calibrated in the field.
9. Repeat Step 4 to Step 7 for the remaining frequencies.
13.5 Tuning Setup (Wireline)
13.5.1 Wireline Receive Level Tuning
The procedure outlined in this section is used to set the output level on the Wireline board’s Rx path
for a given RF signal deviation on the received signal. Perform this procedure during initial Wireline
installation or any time the Rx audio level needs adjustment.
13.5.1.1 Tuning Procedure
1. Connect the radio’s receiver antenna port to the Communication Analyzer.
2. Power the base station/repeater from either an AC or DC source.
3. Launch the Tuner application and click the “Read” button to read the softpot values.
4. Select “Wireline Receive Level” under the Rx menu in the tree view (Refer to Figure 13-6).
