Chapter 9, 264 Using the Analog Call Processing Subsystem
Using the CALL CONTROL Screen to Test Call Processing Functions
1
Couple the variable-frequency notch filter to AFGen1.
This step is only required if audio testing is to be done on the mobile station. This step
couples the variable-frequency notch filter to the output frequency of AFGen1 (audio
frequency generator1). The notch filter is used when making SINAD measurements.
AFGen1 is used to generate the audio tone for the SINAD measurement. Coupling the
notch filter to the audio source ensures the most accurate measurement.

2. Verify that the Test Set configuration information is appropriate for the mobile station
to be tested. Check the following fields:
a
System Type
- Select the type of cellular system to be simulated
(AMPS, NAMPS, TACS, JTACS).
NOTE:
If the
System Type
field was modified in step 2.a. the control channel will become active
since modifying this field automatically activates the control channel.Refer to the

System Type
field was modified in step 2. a. the control channel will become
active since modifying this field automatically activates the control channel. Refer to the
“Call Control Screen” chapter in the HP 8924C Reference Guide.
c
Cntl Channel
- Set the control channel number to be used by the Test
Set.
NOTE:
If the
Cntl Channel
field was modified in step 2. c the control channel will become
active since modifying this field automatically activates the control channel. Refer to the
“Call Control Screen”
chapter in the HP 8924C Reference Guide.
d
Amplitude
- Set the output power of the Test Set’s transmitter (that
is, the output power of the Test Set’s RF Generator).
e
SID
- Enter the system identification number of the Test Set as a
decimal number.
f
Chan:
(right-hand field) - Enter the
voice channel number which will be
assigned to the mobile station by the Test Set as either an initial voice
channel assignment or as a handoff voice channel assignment.
