Step13 In IP Message, type the command “-40DBM = -40“.
Receiver Calibration Test
Step1 Inject a signal with amplitude of -95dBm into the TX/RX1 antenna port.
Step2 Set the mobile to receiver1 using the command “receiver=1”
Step3 In IP Message, type the command “noise”, the equipment must measure -95
dBm +/- 2.
Transmitter Alignments
Perform the following steps to adjust transmit data:
Step1 Set the service monitor to TX.
Step2 Set the “tune freq” of the service monitor to the mobile transmit frequency
(For example 799 MHz).
Step3 Set the transmit parameters as follows: Tune Mode: Manual, Input port =
RFIN,
IF filter: 15 kHz, Filter 1: 50 Hz HPF, Filter 2: 15 kHz LPF.
Step 4 Connect the RFIN/OUT of the monitor to TX/RX1 port of the radio.
When connecting the TX/RX1 port to any equipment than antenna
and HP service monitor make sure to use a power attenuator.
Step 5 Use IPMessage to set power to 150 by using the command “txpower=150”.
Step 6 Turn the carrier on by using the command “txkey=1”.
Step 7 Check the transmit frequency with monitor and record the offset frequency.
Step 8 Turn the carrier off using the command “txkey=0”.
