:TRACe Subsystem
This subsystem contains commands related to the transfer of trace data to and from the instrument.
:TRACe:PREamble? <trace type>
Title
Trace Header Transfer
Description
Returns trace header information for the specified trace. The <trace type> must be one of the following: SINGle|MULTi|PVTFrame|PVTSlot|DEMod
Data can be transferred to and from the 5 available display trace types. Use the commands in the MMEMory subsystem to store and recall traces from the instrument memory. The response begins with an ASCII header. The header specifies the number of following bytes. It looks like #AX, where A is the number of digits in X and X is the number of bytes that follow the header. Note that the instrument must be set in the selected view. Use the CONFigure commands to set the unit to the selected view. Parameters are returned in comma-delimited ASCII format. Each parameter is returned as “NAME=VALUE[ UNITS],” Valid parameters are shown in GSM Parameter Names.

Trace Data Transfer
Description
This command transfers trace data from the instrument to the controller. The <trace type> must be one of the following: SINGle|MULTi|PVTFrame|PVTSlot|DEMod.
The format of the block data in the query form is specified by :FORMat:DATA. The block data in the command form is always sent in ASCII format. The response begins with an ASCII header that specifies the number of data bytes. It looks like #AX, where A is the number of digits in X and X is the number of bytes that follow the header. Each data point is separated by a comma delimiter. Trace setup information can be acquired using :TRACe[:DATA]:PREamble?.
Use the commands in the MMEMory subsystem to store and recall traces from the instrument memory. Except for DEMod, there is only one value per data point. For DEMod, each data point is represented by 2 values, 4 bytes each: IData (no units), and QData (no units). For SINGle, MULTi, PVTFrame, and PVTSlot, the unit is in dBm. Note that the instrument must be set in the selected view. Use the CONFigure commands to set the unit to the selected view.
