Configuring the Forward Sync Channel (F-Sync/Sync)

Last updated: November 10, 2006

The F-Sync/Sync channel parameters are configured using the CALL:SYNC subsystem commands. To set the parameters using the test set's front panel, see How Do I Change Generator Information?

state.

Fixed F-Sync/Sync Parameters

The F-Sync/Sync Walsh code is fixed at code channel number 32.

GPIB Examples:

Setting the F-Sync State and Level (complex command)

 
OUTPUT 714;"CALL:SYNC -16 DB"

would set the F-Sync state on and set the level to -16 dB. See CALL:SYNC[:SLEVel][:SELected] .

Querying the F-Sync Level

 
OUTPUT 714;"CALL:SYNC:LEVel?"

would query the last setting that was made to the F-Sync level. See CALL:SYNC:LEVel[:SELected] .

Operating Considerations

The Walsh code number for the F-Sync channel is fixed at code 32 of the Walsh 64 set.

There are some format changes for Sync Channel message sent to the mobile station on the Sync channel as required for different protocol revisions. See Settable Fields in Overhead Messages .
