Sweep/Control
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 analyzer. 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.
When in a split screen display each window may have its own value for points.
When sweep points is changed, an informational message is displayed, "Sweep points changed, all traces
cleared."

Dependencies: • This function is not available when signal identification is set to On in
External Mixing
• Neither the knob nor the step keys can be used to change this value. If it is
tried, a warning is given.
• Clipped to 1001 whenever you are in the Spectrogram View in all models
but MXE, clipped to 20001 whenever you are in the Spectrogram View in
MXE
• Grayed out in measurements that do not support swept. Forceful message
–221.3200
• Blanked in modes that do not support Swept
• Grayed out if Normalize is on; you can’t change the number of sweep
points with Normalize on, as it will erase the reference trace.
