and the Number of Points can vary as the Stimulus Step Size is changed. The Span is reduced
as little as possible so that the condition Stimulus Step Size = (Stop – Start) / (Number of Points
– 1) can be fulfilled. Changing the Span modifies the Stimulus Step Size.
This setting is valid for linear frequency sweeps only. It does not apply to logarithmic and
segmented sweeps, power, time or CW Mode sweeps.
Remote control:
Sweep Time
Opens a dialog to vary the measurement time for a sweep or delay the start of each sweep.
• Auto minimizes the sweep time. If this option is checked, the input fields Sweep Time and
Meas. Delay can not be edited. Sweep Time indicates the estimated sweep time, taking into
account the current measurement settings, the Meas. Delay is 0 s. The Sweep Time and Meas.
Delay values are maintained until changed explicitly if Auto is switched off.
• Sweep Time is the total measurement time for the sweep. The minimum sweep time to be set is
equal to the estimated value in the Auto mode. Setting a larger sweep time is equivalent to
defining a Meas. Delay before each partial measurement.
• Meas. Delay sets a delay time allowing the DUT to settle before the hardware settings of the
analyzer are changed and a new partial measurement is started.
Meas. Delay
A delay time before the start of each partial measurement increases the accuracy, in particular in
measurements on DUTs with long settling times (e.g. quartzes, SAW filters). As an alternative to
increasing the delay (and thus the total sweep time), it is possible to select Alternate sweep.
The Auto and Sweep Time settings are not active in the Time and CW Mode sweep types. The Meas.
Delay is taken into account for all sweep types.
In Segmented Frequency sweeps, the sweep time parameters can be set independently for each
segment; see Define Segments. Sweep Time opens a message box indicating to total sweep time, i.e.
the sum of the individual sweep segment times.
