3.2.9.2 Sweep Config
Accesses controls that enable you to configure the Sweep and Control functions of
the instrument, such as Sweep Rules.
Sweep Time Rules
Switches the instrument between NORMal and ACCuracy sweep states.
Setting Auto Sweep Time to ACCuracy results in slower sweep times (usually about
three times as long) but yields better amplitude accuracy for CW signals. The
instrument amplitude accuracy specifications only apply when Auto Sweep Time is
set to ACCuracy.
Additional amplitude errors that occur when Auto Sweep Time is set to NORMal are
usually well under 0.1dB, though this is not guaranteed. Because of the faster
sweep times and still low errors, NORMal is the preferred setting of Auto Sweep
Time. Auto Sweep Time is set to NORMal on a Preset. This means that in the Preset
state, instrument amplitude accuracy specifications do not apply.

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
