472 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
23 Sweep
Points
Sets the number of points per sweep, from 101 to 8192 in non-zero span and 2 to 8192 in
zero span. Resolution of setting the sweep time will depend on the number of points
selected. If Factory Preset is selected, or the N8201A power is cycled, the number of points
per sweep will default to 601. The current value of points is displayed parenthetically, next
to the sweep time in the lower-right corner of the display.
Changing the number of points has several effects on the N8201A. Since markers are read
at the point location, the marker reading may change. All trace data for the active trace is
cleared. If sweep is set to Cont (Sweep, Sweep Cont), a new sweep begins immediately. If
average is set to On (press BW/Avg, Average), the averaging starts over with a count of 0. If
limit lines are set to On (press Display, Limits, Limit 1 or 2, Edit), the limit lines are updated.
By selecting a number of sweep points greater than 601, you are optimizing frequency
resolution and accuracy while accepting a reduced measurement speed. In addition to
sweep points, the span, resolution bandwidth, video bandwidth, average detection, and
center frequency also affect measurement speed.
This function is coupled with the span setting. Increasing the span can change the number
of sweep points. In order to maintain accurate measurements, the number of sweep points
is increased if required to keep the width of each sweep point at most 150 MHz.
When zone span is set to On (press Span, Zone. Zone), each window has its own value for
points.
