7-10 :TRACe Subsystem
This subsystem contains commands related to the transfer of trace data to and from the
instrument.
:TRACe:PREamble? <trace type>
Title: 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 in
Table 7-1, “Available Parameters in WiMAX and Mobile WiMAX Mode”
on page 7-22.
Parameter: <trace type>
