Query about all defined trace names.
Note:
IFPAN
trace is only available with the software option EM510IM (ITU Measurement) or software option
EM510SU (Spectrum Unit) installed.
Parameters:

TRACe
.
[:DATA] <trace_name>, <numeric_value> {, <numeric_value>} | <block>
Writing data to a trace.
Note:
Only the suppress traces can be written to.
Error messages
:
If the trace name is unknown or not identical with a suppress trace, error -141 "Invalid character data" is
generated.
If too many data are loaded in a suppress trace, error -223 "Too much data" is generated.
Parameter:
<trace-name>
name of the trace to be written to as
<Character Data>
SSTART
<numeric_value>
list of frequencies. If the list is not complete, the rest of the trace
is filled with 0.
Note:
In contrast to the SCPI standard a single value is not used for the
complete trace!
<block>
As an alternative to the frequency list a
<Definite Length
Block>
can be transmitted with the following structure:
Frequency list with frequencies in Hz, 4 bytes per frequency.
*RST state:
No change of trace contents at *RST.
Example:
TRACe SSTART, 123.475 kHz, 118000, 98.550 kHz
