Setting Description
Center The frequency at the center of the selected Span.
Start The lowest frequency in the span.
Stop The highest frequency in the span.
Step Size Sets the increment/decrement size for Center, Start and Stop values.
Span The difference between the start and stop frequencies. This is the measurement
bandwidth for the general signal viewing displays.
Dwell time (DPX Spectrum
display only) The amount of time the DPX sweep remains in a frequency segment collecting data
and updating the bitmap and traces before moving on to the next higher frequency
segment. The minimum Dwell Time setting is 50 ms, the normal update rate for DPX
computations. Maximum Dwell Time per frequency segment is 100 s. The number of
frequency segments and their start/stop frequencies are internally determined based on
span, acquisition bandwidth, RBW and other parameters.
Max Span Sets the Span to the maximum value.

Center, Start, Stop, and Span Frequencies Are Correlated
Changing the values for Center frequency, Start frequency, Stop frequency or Span will change the values
for the other settings, depending on which setting you change. For example, if you change the Center
frequency, the Start and Stop frequencies will be adjusted automatically to maintain the same Span.
Note however that if the Start and Stop frequencies are changed so that they are closer than the minimum
span setting, the Start and Stop frequencies will be adjusted to maintain the minimum Span setting.
