ACP: 29 ms
State Saved Saved in instrument state
Min Other than non-sweeping hardware: Typically, 1 ms
Non-sweeping hardware: N/A
In the ACP measurement, when Meas Method is Fast Power, the minimum sweep time is span-
dependent and automatically calculated
Max Other than non-sweeping hardware: 4000 s
Non-sweeping hardware: N/A
Annotation The sweep time is displayed in the lower-right corner of the screen. The number of points is displayed
parenthetically, as:
Sweep 13.3 ms (1001 points)
A “#” mark appears before “Sweep” in the annotation when it is switched from Auto to Manual

Minimum Acquisition Time
Available on non-sweeping hardware.
Specifies the minimum acquisition time for each “chunk” of the measurement result.
The instrument automatically divides Span into multiple chunks if needed.
Therefore, the total signal acquisition time for the entire Span is:
~(>~Minimum Acquisition Time) * (The number of chunks)
