Configuring the F-SCH (Forward Supplemental Channel)
Configuring the F-SCH (Forward Supplemental Channel)
The F-SCH channel parameters are configured using the following call processing subsystem functions and
commands.
Settable F-SCH Parameters
• F-SCH level.
• F-SCH state.
• F-SCH data rate
• F-SCH encoder type (convolutional or turbo)
Fixed F-SCH Parameters
The F-SCH Walsh code is fixed at code channel number 3.
When the F-SCH data rate is below 19.2 kbps, the forward channel convolutional encoder will be selected
regardless of the encoder setting.
GPIB Examples:
Setting the F-SCH level and state (complex command)
OUTPUT 714;"CALL:SCH -15.6 DB"
would set the F-SCH state on and set the level to −15.6 dB. See “CALL:SCHannel[:SLEVel][:SELected]” .
Setting the F-SCH data rate
OUTPUT 714;"CALL:SCH:DRATE:RCONFIG3 BPS38400"
would set the F-SCH data rate for forward channel radio configuration 3 to 38400. See
“CALL:SCHannel:DRATe:RCONfig3” .
Operating Considerations
The F-SCH is available only when the operating mode is set to IS-2000 Test.
The F-SCH channel in forward channel radio configurations 1 and 2 is supported only when operating mode is
set to IS-2000 Test.
