. :CATalog?
Query of all defined trace names
Parameters:
none
Result:
"MTRACE", "ITRACE", "IFPAN", "SSTART", "SSTOP", “UDP”
TRACe|DATA
. [:DATA] <trace_name>, <numeric_value> {, <numeric_value>} |
<block>
Writing data to a trace. Existing data is lost.
Remark:
Only the suppress traces can be written to.
Error:
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
Note: These are not strings but predefined keywords. I.e.:
They cannot be included in quotes.
<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, 8 bytes per
frequency.
*RST state:
No change of trace contents at *RST.
Example:
TRACe SSTART, 123.475 MHz, 118000000, 98550 kHz
