Trace/Detector
•
The average/hold count k is set to 1, so that the next time the average trace is displayed it
simply represents one trace of new data
•
A new sweep is initiated.
•
Once the new sweep starts, the trace is overwritten with current trace data as the first trace of
the new average
Remember that restarting averaging also restarts Max Hold and Min Hold, as there is only one count
for Trace Average and Hold.
Max Hold
In Max Hold type the analyzer maintains and displays a max hold trace, which represents the
maximum data value on a point-by-point basis of the new trace data and previous trace data.
Pressing the Max Hold key for the selected trace, or sending the :TRAC:TYPE MAXH command for
the specified trace, sets the trace type to Max Hold, causes the trace to be cleared, and causes the
Max Hold
sequence to be (re)started, even if you are already in Max Hold.
When in Max Hold, if a measurement-related instrument setting is changed, the Max Hold sequence
restarts and a new sweep is initiated but the trace is not cleared.
Restarting the Max Hold sequence means:
•
The average/hold count k is set to 1, so that the next time the max hold trace is displayed it
simply represents one trace of new data
•
A new sweep is initiated.
Remember that restarting Max Hold also restarts averaging and Min Hold, 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 Max Hold:
−
They pay no attention to the Average/Hold number; “Single” for Max 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 Max Hold on a Restart or Single or INIT:IMM (changing a measurement
parameter like frequency or bandwidth etc would still restart the max hold).
