Trace/Detector
if the trace is the target of a Copy or participant in an Exchange
if the trace is cleared using the Clear Trace function (below)
When a trace becomes active (Update = On), the trace is cleared, the average count is reset, and a new
sweep is initiated.
Traces which are blanked (Display = off) do not display nor appear on printouts but are otherwise
unaffected. They may be queried and markers may be placed on them.
Note that the action of putting a trace in Display = Off and/or Update = Off does not restart the sweep
and does not restart Averaging or Hold functions for any traces.
Note also that whenever you set Update to On for any trace, Display is set to On for that trace.
Detector
Selects a detector. The detector selected is then applied to the selected trace.
For the SCPI UI, two commands are provided. One is a legacy command, which affects all traces. There
is also a command which is new for the X-Series, which uses a subopcode to specify to which trace the
specified detector is to be applied.
The three detectors on the second page of the Detector menu, Quasi Peak, EMI Average, and RMS
Average, are referred to collectively as the “CISPR detectors” because their behaviors are specified by
the CISPR 16–1–1 specification.

Example DET:TRAC AVER -- Sets trace 1’s detector to average
DET:TRAC1 AVER -- Sets trace 1’s detector to average
DET:TRAC2 SAMP -- Sets trace 2’s detector to sample
Notes When a detector selection is made, the menu returns to the previous menu.
Selecting any CISPR detector on any active trace sets the EMI Standard to
CISPR.
