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
The instrument 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. Details of the count limiting behavior may be found under Avg|Hold
Number under Meas Setup.
Pressing Max Hold for the selected trace, or sending :TRAC:TYPE MAXH for the
specified trace, sets the Trace Type to Max Hold, clears the trace , initiates a new
sweep, and restarts the hold sequence, even if you are already in Max Hold.
When in Max Hold, if a measurement-related instrument setting is changed(that is,
one which requires new data to be taken, like Center Frequency or Attenuation), 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.
Min Hold
The instrument maintains and displays a min hold trace, which represents the
minimum data value on a point-point basis of the new trace data and previous trace
data. Details of the count limiting behavior may be found under Avg|Hold Number
under the Meas Setup functions.
Pressing Min Hold for the selected trace, or sending :TRAC:TYPE MINH for the
specified trace, sets the Trace Type to Min Hold, clears the trace, initiates a new
sweep, and restarts the hold sequence, even if you are already in Min Hold.
When in Min Hold, if a measurement-related instrument setting is changed(that is,
one which requires new data to be taken, like Center Frequency or Attenuation), the
Min Hold sequence restarts and a new sweep is initiated but the trace is not cleared.
Restarting the Min Hold sequence means:
