2.2.4.1 Sweep Time
Set the time needed for the spectrum analyzer to finish a sweep within the span range. The sweep
time can be set in “Auto” or “Manual” mode and the default is “Auto”.
In non-zero span, the analyzer selects the shortest sweep time on the basis of the current
RBW and VBW settings if Auto is selected.
Decreasing the sweep time would speed the measurement. However, an error may be caused
if the specified sweep time is less than the minimum sweep time in Auto coupling; at this point,
“UNCAL” is shown in the status bar on the screen
Table 2- 15 Sweep Time
2.2.4.2 Sweep Rule
The analyzer provides two sweep time rules to meet the different sweep time requirements:
Speed: Activates the default fast sweep time rule.
Accuracy: Activates the normal sweep time rule to ensure the measurement accuracy. Speed
sweep time rule provides a fast measurement function that decreases the sweep time. Using Fast
Sweep will decrease the measurement accuracy.

the screen varies with the process of the sweep.

analyzer is sweeping continuously.
