TRACe|DATA
. :FEED
. . :CONTrol <trace_name>, ALWays|SQUelch|NEVer
Determines how a trace is loaded with data. Data are always added to a trace;
i.e. the trace is not emptied first (see also TRAC:FEED:CONT:RECM). To
empty a trace, it must be read with TRACe?
Parameters:
<trace-name> see TRACe[:DATA]?
ALWays each measurement is stored in the trace. This starts recording.
SQUelch data are first stored, if the signal has exceeded the squelch
threshold defined in the
OUTPut:SQUelch subsystem. This starts recording.
NEVer do not store any data in the trace. This stops recording.
Remark:
For IFPAN Trace, only ALWays or NEVer can be selected.
Error:
If trace name is unknown, an error -141, "Invalid character data" will be
generated.
*RST state:
NEVer
Example:
TRACe:FEED:CONTrol MTRACE, ALWays
