Saving and recalling:
Saving and recalling trace data together with the device settings to/from the device-internal hard disk
or to/from a memory stick/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
".
Transfer format:
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
'TRACE3'.
The transfer of trace data from the control computer 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.
The parameter of the query is the trace name TRACE1 to TRACE3, it indicates which trace memory
will be read out.
6.20.2 Number and Format of the Measurement Values for the Different
Operating Modes
The number of measurement values depends on the instrument setting:
Analyzer mode (span > 0 and zero span):
155 up to 30001 (default 625) results are output in the unit selected for display.
For spurious emissions measurement the number of results is the sum of all sweep points, specified
in the sweep list configuration.
FORMat REAL, 32
is to be used as format for binary transmission, and
FORMat ASCii
for ASCII
transmission.
SPURious reads the peak list in the spurious measurement. As results a list of frequency, level and
delta to limit line values is returned. A delta limit of +200dB indicates no limit check is active.
With AUTO PEAK detector, only positive peak values can be read out.
Trace data can be written into the instrument with logarithmic display only in dBm,
with linear display only in volts.
