TRACe Subsystem
The TRACe subsystem controls access to the instrument’s internal trace memory.
COMMAND PARAMETERS UNIT COMMENT

:TRACe[:DATA] TRACE1| TRACE2| TRACE3| TRACE4, <block> | <numeric_value>
This command transfers trace data from the controller to the instrument, the query reads trace data
out of the instrument.
Example: ":TRAC TRACE1,"+A$ (A$: data list in the current format)
"TRAC? TRACE1"
Features: *RST value: -
SCPI: conforming
Modes: A, VA, BTS, MS
The trace data are transferred in the current format (corresponding to the command FORMat
ASCii|REAL). The device-internal trace memory is addressed using the trace names ’TRACE1’ to
’TRACE4’.
The transfer of trace data from the controller to the instrument takes place by indicating the trace
name and then the data to be transferred. In ASCII format, these data are values separated by
commas. If the transfer takes place using the format real (REAL 32), the data are transferred in block
format (see FORMat subsystem).
The parameter of the query is the trace name TRACE1 to FINAL4, it indicates which trace memory
will be read out.
Saving and recalling trace data together with the device settings to/from the device-internal hard disk
or to/from a floppy is controlled via the commands ":MMEMory:STORe:STATe" and
":MMEMory:LOAD:STATe" respectively. Trace data are selected with
":MMEMory:SELect[:ITEM]:ALL" or "":MMEMory:SELect[:ITEM]:TRACe". Trace data in
ASCII format (ASCII FILE EXPORT) are exported with the command ":MMEM:STORe:TRACe".
The transfer format for the trace data depends on the instrument setting
Analyzer mode (span >0 and zero span):
500 results are output in the unit selected for display.
Note: With AUTO PEAK detector, only positive peak values can be read out.
Trace data can be read into instrument with logarithmic display only in dBm, with
linear display only in volts.
FORMAT REAL,32 is to be used as format for binary transmission.
