8-10 :TRACe Subsystem Mobile WiMAX Commands
8-22 PN: 10580-00319 Rev. N S412E PM
8-10 :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:
SPECtrum|PVTime|ACPR|CONStln|SFLatness|EVSCarrier|EVSY
mbol
Data can be transferred to and from the 7 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. Parameters are returned in
comma-delimited ASCII format. Each parameter is returned as
“NAME=VALUE[ UNITS],” Valid parameter names are shown
inTable 7-1, “Available Parameters in WiMAX and Mobile WiMAX
Mode” on page 7-22.
Parameter: <trace type>
Related Command: :TRACe:DATA?
:TRACe[:DATA]? <trace type>
Title: Trace Data Transfer
Description: This command transfers trace data from the instrument to the
controller. The <trace type> must be one of the following:
SPECtrum|PVTime|CONStln|SFLatness|EVSCarrier|EVSYmbol.
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?
