Users Manual Part 1
Prerequisites:
• Ensure that the RSSI levels for low power setting are properly configured. See Verifying and Tuning
the Receiver RSSI Levels on page 266
.
• Set up the equipment for receiver verification and tuning. See Setting Up the Equipment for
Receiver Verification on page 265.
• Contact your local Motorola Solutions representative or Technical Support to obtain required
password.
WARNING: RF energy burn hazard or equipment damage. Before disconnecting antenna and
connecting signal generator to the antenna connector, ensure that none of the Base Radios is
currently transmitting.
Procedure:
1 Turn on the BR.
2 Enter the BR Test Application mode and log on with dev credentials. See Logging on to the Test
Application on page 242.
NOTICE: If the prompt does not show, wait for the BR to reboot automatically in less
than 30 s.
3 Reset cal_br* values to 0 for high power configuration by performing the following actions:
a Enter the following command:
fcp -orxch1 -pcal_br<receiver number>_hp -v0
b Repeat step 3 a for each branch.
Step example:
fcp -orxch1 -pcal_br1_hp -v0
fcp -orxch1 -pcal_br2_hp -v0
fcp -orxch1 -pcal_br3_hp -v0
4 Turn off the system gain and reset the BR. Type the following commands:
sge -orx_all –soff
reset -ocontrol
5 At the prompt verify the receive frequency for the current Base Radio by typing: freq -orxch1
and record the result.
If displayed frequency is suitable for measurement, continue with step 7.
6 Set the RX frequency. Use the freq -orx_all -f<X> command, where <X> is the receive
frequency.
Step example: To set the receive frequency to 401.0125 MHz, enter freq -orx_all -
f401.0125.
7 Configure the TETRA Signal Generator (VSG) to produce TCH/7.2 logical channel at the Base
Radio’s current RX frequency by performing the following steps:
a Connect signal generator to the antenna connector on top of the
cabinet.
b Set the RF Signal Generator to -40 dBm at the Rx input.
8 Configure the station to decode TCH/7.2 logical channel type. Type
ptm -orx_all -mTCH_72 -s15 -tFrame_Trigger -d-5
