AVC Test Operating Mode
AVC Test Mode Operation Using Automated Receiver Control
The following procedure demonstrates the use of AVC test mode where the base station emulator’s RF
generator frequency, measurement receiver frequency, and expected input power are automatically set by the
call control settings used. This is the most common way to use test mode because it requires less individual
configuration of call parameters.
This procedure provides general programming steps, but is not written around any specific test requirements.
Some of the settings shown are the default power up settings for AVC Test mode.
Putting the mobile in analog test mode at the correct channel number and power setting is the responsibility
of the user.
1. Select AVC Test mode.
OUTPUT 714;”CALL:OPERating:MODE AVCT”
2. Turn on the base station emulator’s RF Generator and set the output level to -50 dBm.
OUTPUT 714;”CALL:POWer -50”
3. Set the AVC channel number to 777.
OUTPUT 714;”CALL:SETup:AVC 777”
4. Set the MS TX Level to two (2). (This is the mobile’s power level setting, not the expected power in dBm.)
OUTPUT 714;”CALL:SETup:MS:ANALog:TXLevel:CELLular 2”
5. Turn the forward channel AVC SAT on.
OUTPUT 714;”CALL:AVCTest:AVC:SATone:STATe ON”
6. Set the SAT color code to SAT1 (5970 Hz).
OUTPUT 714;”CALL:SETup:AVC:SATone SAT1”
7. Turn on internal FM, and set the deviation to 8.0 kHz and the rate to 1004 Hz.
OUTPUT 714;”CALL:FM:INTernal 8 KHZ;INT:FREQuency 1004 HZ”
If you do not want internal FM on, use the FM State command to turn it off:
OUTPUT 714;”CALL:FM:INTernal:STATe OFF”
8. Turn external FM off.
OUTPUT 714;”CALL:FM:EXTernal:STATe OFF”
9. Connect the mobile’s antenna port to the test set’s RF IN/OUT port and put the mobile in analog test mode,
transmitting at power level two on channel 777.
If your mobile’s audio is not muted, you should hear a 1004 Hz tone out of its speaker. If you have an acoustic
or direct connection to the mobile’s audio output, you can make audio measurements through the test set’s
AUDIO IN connections. See “Audio Analyzer Measurement Description” on page 38.
You can also make analog transmit power and frequency stability measurements on the mobile’s reverse
channel carrier. If you modulate your mobile’s carrier, you can measure the frequency modulation
characteristics. See “Analog Transmit Power Measurement Description” on page 37, “Frequency Stability
Measurement Description” on page 57, and “Frequency Modulation (FM) Measurement Description” on page
55.
