Trace/Detector
Select Trace
Determines which trace the type control keys will affect. When you select a trace, it makes that
trace the current trace, so it displays on top of all of the other traces.
Key Path

Dependencies
Traces 1 and 2 cannot be selected (grayed out) when Image Shift is On.
Preset
Trace 1
State Saved
The number of the selected trace is saved in Instrument State
Initial S/W Revision
Prior to A.02.00
Clear Write
In Clear Write type each trace update replaces the old data in the trace with new data. Pressing the
Clear Write
key for the selected trace, or sending the TRAC:TYPE WRIT command for the specified
trace, sets the trace type to Clear Write and causes the trace to be cleared, even if you are already
in Clear Write. Then a new sweep is initiated.
Because pressing Clear Write stops the current sweep and initiates a new one, Trace Average, Max
Hold
and Min Hold data may be interrupted in mid-sweep, and may not accurately reflect the
displayed count. Therefore, when Clear Write is pressed for one trace, Trace Average, Max Hold and
Min Hold
must restart for all traces.
When in Clear Write, if a measurement-related instrument setting is changed, a new sweep is
initiated but the trace is not cleared.

Dependencies
When Signal ID is on, this key is grayed out for Traces 2–6 in Image Supress mode and for

Whenever you press Clear Write or send the equivalent SCPI command, Update is set to On and
Display is set to On.
Automatic detector selection and the VBW:RBW ratio auto rules both depend on the trace type
selections
Preset
After a Preset, any trace that is in Clear Write is cleared (all trace points set to mintracevalue).

The type for each trace is saved in Instrument State
