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:
–
The average/hold count k is set to 1, so that the next time the min hold trace is
displayed it simply represents one trace of new data
–
A new sweep is initiated
Remember that restarting Min Hold also restarts Max Hold and averaging, because
there is only one count for Trace Average and Hold.
Clear and Write | Restart Averaging | Restart Max/Min Hold
Starts the trace writing, as though the "Trace Type" on page 1737 had just been
selected. The effect is exactly the same as reselecting the current Trace Type again
