–
They ignore the Average/Hold number; Single for Max Hold causes one sweep
only, so switching to Single stops after the current sweep, and switching to Cont
starts again without clearing the accumulated result
–
Max Hold is not cleared on a Restart, Single or :INIT:IMM, but changing a
measurement parameter, like frequency or bandwidth etc., still restarts the Max
Hold

Notes
The legacy :TRACe:MODE command is retained for backwards compatibility. In conjunction with the
legacy :AVErage command, it works as follows:
–
:AVErage ON|OFF sets/clears a variable that we will call average for the sake of this
discussion. This variable is maintained by the instrument solely for backwards compatibility. See
the [:SENSe]:AVERage[:STATe] command description below
–
:TRACe:MODE WRITe sets :TRACe:TYPE WRITe (Clear/Write) unless average is true, in
which case it sets it to :TRACe:TYPE AVErage. It also sets :TRACe:UPDate ON,
:TRACe:DISPlay ON, for the selected trace
–
:TRACe:MODE MAXHold sets :TRACe:TYPE MAXHold (Max Hold). It also sets
:TRACe:UPDate ON, :TRACe:DISPlay ON, for the selected trace
–
:TRACe:MODE MINHold sets :TRACe:TYPE MINHold (Min Hold). It also sets
:TRACe:UPDate ON, :TRACe:DISPlay ON, for the selected trace
–
:TRACe:MODE VIEW sets :TRACe:UPDate OFF, :TRACe:DISPlay ON, for the selected
trace
–
:TRACe:MODE BLANk sets :TRACe:UPDate OFF, :TRACe:DISPlay OFF, for the
selected trace
The query returns the same value as :TRACe:TYPE?, meaning that if you set :TRACe:MODE:VIEW
or :TRACe:MODE:BLANk, the query response will not be what you sent
:TRACe[n]:MODE was formerly used to set the type or “writing mode” of the trace. At that time,
View and Blank were writing modes. The new :TRACe:TYPE command should be used in the future,
but :TRACe:MODE is retained to provide backwards compatibility
In X-Series, unlike earlier instruments, 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 operations that restart
Averaging (for example, the Restart key) now also restart Min Hold and Max Hold
As a result of these changes, legacy code that restarts averaging while retaining a running Max Hold
will need to be rewritten, because the Max Hold will now restart when the Average does
