Trace/Detector
Remember that restarting Min Hold also restarts Max Hold and averaging, as there is only one count
for Trace Average and Hold.

Dependencies
When Signal ID is on, this key is grayed out for Traces 2–6 in Image Supress mode and for
Traces 3–6 in Image Shift Mode.
When the Average/Hold switch in the Mode Setup, Legacy Compatibility menu is in the
“Legacy” position, the following is true for traces in Min Hold:
−
They pay no attention to the Average/Hold number; “Single” for Min Hold causes one
sweep only, so going to Single stops after the current sweep, and going to Cont starts you
going again without clearing the accumulated result
−
They don’t clear the Min Hold on a Restart or Single or INIT:IMM (changing a measurement
parameter like frequency or bandwidth etc would still restart the min hold).
Couplings
Affected by Average Type and Average/Hold Number.
Whenever you press Min Hold 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 Min Hold is cleared (all trace points set to maxtracevalue).
State Saved
The type for each trace is saved in instrument state
Backwards Compatibility
Notes
In the X-Series, unlike earlier analyzers, Max Hold and Min Hold now obey the Average Number
and counts up to a terminal value as Average always has.
As the Average/Hold Number now affects Min Hold and Max Hold, the things that restart
Averaging (eg, the Restart key) now also restart Min Hold and Max Hold.
As a result of these changes, users who used to restart averaging while retaining a running Min
Hold will find that they need to rewrite their code, because the Min Hold will restart when the
Average does.
Also, previous to the X-Series,
−
pressing Min Hold while already in Min Hold (or doing so remotely) had no effect. Now it
will clear the trace and restart the sweep and the Min Hold sequence.
−
changing the vertical scale (Log/Lin or dB/div) of the display restarted Max Hold and Min
Hold. This is no longer the case in the X-Series.
