3.10.9 Sweep
Accesses controls to configure and control the acquisition of data, and the X-axis
parameters of the instrument.
Depending on the selected mode and measurement, these controls might include:
Sweep Time, Continuous/Single, Pause/Resume, X Scale and Number of Points.
3.10.9.1 Sweep/Control
Accesses controls that let you operate the sweep and control functions of the
instrument, such as Sweep Time and Continuous/Single.
Sweep Time
Controls the time the instrument takes to sweep the current frequency span in
swept measurements, displays the sweep time in swept measurements, and
displays the equivalent Sweep Time in FFT measurements.
NOTE
In instruments without sweeping hardware this control may be labeled
Acquisition Time
When Sweep Time is in Auto, the instrument computes a time that will give accurate
measurements based on other settings of the instrument, such as RBW and VBW.
You can select a shorter sweep time to improve the measurement throughput (with
some potential unspecified accuracy reduction), but the Meas Uncal indicator will
come on if the Sweep Time you set is less than the calculated Auto Sweep time.
You can also select a longer sweep time, which can be useful (for example) for
obtaining accurate insertion loss measurements on very narrowband filters.
