Transmitter Verification
This procedure provides commands and responses to verify proper operation of the
transmit path for the Power Amplifier.
Procedure 6-7 How to Verify the Transmitter
Connect the Service Cable between the service terminal and the Service port. Log in to the
1
Base Radio.
At the prompt, type power -otxch1 -a0. This command dekeys the transmitter.

To key the transmitter with a T2 type channel type these three commands:
These commands set the transmitter to a specified power (in Watts) without altering any
programmed parameters. For example, to key the Power Amplifier to 36W, type power -otxch1
-a36.

The following procedure requires the MTS 2 or MTS 4 to be out of service. Unless it is
already out of service, Motorola recommends performing this procedure during off-peak
hours. This minimizes or eliminates disruption of service to system users.
In order to avoid the risk of causing a high bit error rate to occur, do not use 385.572MHz
and 419.175MHz as receiving frequencies in the Base Radios of the MTS.
Contact your local Motorola representative or Technical Support to obtain password.
The following commands, keys the transmitter. Make sure that transmission only
occurs on licensed frequencies or into an RF dummy load. To ask for the current
transmitter frequency, type: freq -otxch1. To change the transmit frequency, type:
vco -otx_all -fXXX.XXXX. For example, to set the transmit frequency to 410.0125
MHz, type: vco -otx_all -f410.0125.
• enable -otx_all –son
• ptm -orx_all -mTx_T2 -s15 -tNo_Trigger -d0
• power -otxch1 -aXX
To transmit a TCH 7.2 channel type, type: ptm -orx_all -mTCH_72 -s15
-tNo_Trigger -d0.
The measurement equipment setting for MCC, MNC and BCC:0.
Burst Type: NCDB.
