Points
Sets the number of points taken per sweep, and displayed in the traces. The current
value of points is displayed parenthetically, next to the sweep time in the lower-right
corner of the display. Using more points provides greater resolution. Using fewer
points compacts the data and decreases the time required to access a trace over the
remote interface.
Increasing the number of points does not increase the sweep time. However, it can
slightly impact the trace processing time and therefore the overall measurement
speed. Decreasing the number of points does not decrease the sweep time, but it
may speed up the measurement, depending on the other sweep settings (for
example, in FFT sweeps). Fewer points will always speed up the I/O.
Due to minimum sweep rate limitations of the hardware, the minimum sweep time
available to the user will increase above its normal value of 1 ms as the number of
sweep points increases above 15001.
Changing the number of sweep points has several effects on the instrument. Since
markers are read at the point location, the marker reading may change. The sweep
time resolution will change. Trace data for all the traces will be cleared and, if Sweep
is in Cont, a new trace taken. If any trace is in average or hold, the averaging starts
over.
Due to sweep time quantization issues, the knob and up/down keys cannot be used
to adjust the number of points.
When in a split-screen display, each window may have its own value for points.
When sweep Points is changed, an informational message "Sweep points changed,
all traces cleared" is displayed, and in 5GNR Mode, Auto Sweep Points is set to OFF
(0).
