where
The display "Sweep N of N" does not change any more until a new start is triggered.
In the SINGLE SWEEP mode, the number of sweeps is triggered with SWEEP
START . The sweeps are stopped when the selected number of sweeps is attained.
The number of the current sweep and the total number of sweeps are shown on the
display: "Sweep 3 of 200".
VIEW The VIEW softkey freezes the current contents of the trace memory and displays it.
If a trace is frozen by VIEW , the instrument settings can be changed without the dis-
played trace being modified (exception: level display range and reference level, see
below). The fact that the trace and the current instrument setting do not agree any
more is indicated by an enhancement label "*" at the right edge of the grid.
If in the VIEW display mode the level display range ( RANGE ) or the reference level
( REF LEVEL ) are changed, R&S FSP automatically adapts the measured data to
the changed display range. This allows an amplitude zoom to be made after the
measurement in order to show details of the trace.
Remote command:
DISP:WIND:TRAC:MODE VIEW
BLANK The BLANK softkey activates the blanking of the trace on the screen.
Remote command:
DISP:WIND:TRAC OFF
SWEEP
COUNT The SWEEP COUNT softkey activates the entry of the number of sweeps used for
averaging. The allowed range of values is 0 to 30000 and the following should be
observed:
• Sweep Count = 0 means running averaging
• Sweep Count = 1 means no averaging, maxhold or minhold is carried out
• Sweep Count > 1 means averaging over the selected number of sweeps; in the
continuous sweep mode averaging is performed until the set number of sweeps
is attained and is then continued as running averaging.
The default setting is running averaging (Sweep Count = 0). The number of sweeps
used for averaging is the same for all active traces in the selected diagram.
Remote command:
