Sweep
Sets sweep-related parameters, such as sweep time, sweep points, and sweep
mode.
Sweep Points
Sets the number of points acquired in each sweep, i.g. the number of the trace
points.
Remarks:
With the increase of the sweep points, the frequency resolution of the marker
will increase with it, but the sweep speed will decrease with it.
Due to the limitation of the minimum interval of sweep points, when the number
of sweep points is increased, the sweep time will be prolonged.
Changing the number of the sweep points will affect multiple parameters of the
system. Therefore, the system will make a new sweep and measurement again.
You can use the numeric keys, the knob, and the arrow keys on the front panel
to modify this parameter; also you can modify it on the touchscreen. For details,
refer to descriptions in "Parameter Setting".

Sweep Time
Sets the time required for the spectrum analyzer to complete one sweep operation
within the span range.
Remarks:
You can use the numeric keys, the knob, and the arrow keys on the front panel
to modify this parameter; also you can modify it on the touchscreen. For details,

When RBW is smaller than 1 kHz, the spectrum analyzer starts to perform FFT
sweeps. At this time, the Sweep Time menu is disabled and grayed out.
