CMD 80 Digital Radiocommunication Tester User Manual
Analog. Analog operation is possible only if Option B82 (Analog Mode) is
installed.
All command headers for configuring the analog base station simulator in the
tester begin with CONFigure:ABSTation. The commands set or query the
following parameters:
H
Frequency parameters for the control channel and voice channel
H
Source level
H
SAT (or DSAT) color code
H
SAT (or DSAT) peak deviation
H
Mobile attenuation code to control mobile station power level
H
Location ID
H
System ID
H
Paging duration
Some of the configuration commands can only be used when the tester is in a
particular state, while the other commands have different effects in different
states. Almost all commands can be used in the IDLE state to set the values with
which the analog base station turns on. In other states the commands are limited
to prevent disruption of communication between the analog base station and the
mobile station. The limitations associated with each command are given as part
of the command descriptions below. All queries may be used in any system state.
NOTE
. The FREQuency:VCHannel and FREQuency:SCCode commands will
perform a handoff to perform the settings change when the instrument is in the
ACE state.
The frequency configuration commands have the following final header
keywords and parameters:
H
FREQuency:CCHannel <RF channel number> (query FREQuency:CCHan-
nel?) — sets the channel number for the control channel.
H
FREQuency:VCHannel <RF channel number> (query FREQuency:VCHan-
nel?) — sets the channel number for the voice channel.
H
FREQuency:SCCode <SAT color code number> (query FREQuen-
cy:SCCode?) — sets the SAT color code value used when a call is estab-
lished.
H
FREQuency:SYSTem? — returns the system indicator (A or B) for the
control channel as defined in IS–95.
