When you change the value of the dwell time, the scan time of the selected range will be changed
accordingly, based on the calculation Scan Time = Dwell Time x (ScanPoints – 1).
The Dwell Time Auto selection is only available when in Smooth Scan. In Dwell Time Auto, dwell
time will be set according to the SA- Normal sweep time rules for the active trace detector.
If the calculated auto dwell time is greater than the maximum dwell time, a warning message
"Setting Alert; Sweep Rate Unavailable" is displayed, and the dwell time will be set to the maximum
value; if the dwell time is set to a value less than the calculated auto dwell time, a warning message
"Meas Uncal" is displayed.
Auto Dwell Time and Auto Scan Time are always coupled.

The allowable min value is dependent on Range Span and Scan Points.
The Max value depends on the Scan Type and Step Size of the selected range.
When in Smooth (Swept) Scan, the max value depends on the number of Scan Points, where the
latter is determined by Step Size: Max Dwell time = Max Scan Time/ (Scan Points–1). The Max Scan
Time is 4000 sec.
When in Discrete (Stepped) Scan, the max value is fixed to 100 s.
