"Freq Step Size" = ("Stop Frequency" – "Start Frequency") / ("Number of Points" –
1)
can be fulfilled. Changing the "Start Frequency" and "Stop Frequency" modifies the
"Freq Step Size".
●
If the sweep range is defined via "Center Frequency" and "Span Frequency", both
the "Span Frequency" value and the "Number of Points" can vary as the "Freq Step
Size" is changed. The "Span Frequency" is reduced as little as possible so that the
condition
"Freq Step Size" = "Span Frequency" / ("Number of Points" – 1)
can be fulfilled. Changing the "Span Frequency" modifies the "Freq Step Size".
Note:
●
This setting is valid for linear frequency sweeps only. It does not apply to logarith-
mic and segmented sweeps, power, time or CW Mode sweeps.
●
Decreasing the "Freq Step Size" generally increases the measurement time.
Remote command:
[SENSe<Ch>:]SWEep:STEP
Sweep Time / Auto
Varies the measurement time for a sweep or delays the start of each sweep.
●
"Sweep Time" is the total measurement time for the sweep. The minimum possible
sweep time is equal to the estimated value in "Auto" mode. Setting a larger sweep
time is equivalent to defining a Meas Delay before each partial measurement.
●
"Auto" minimizes the sweep time. The Meas Delay is set to 0 s. "Sweep Time" indi-
cates the estimated sweep time, depending on the current measurement settings.
The "Sweep Time" and "Meas Delay" values are maintained until changed explicitly
if "Auto" is switched off.
If a time sweep is active, "Sweep Time" cannot be modified. The analyzer uses the
previously defined sweep time settings.
In "Swept" frequency sweep mode, the "Sweep Time" is undefined. The "Sweep Time"
field is cleared and disabled.
Remote command:
[SENSe<Ch>:]SWEep:TIME
[SENSe<Ch>:]SWEep:TIME:AUTO
Meas Delay
Adds a delay time before the start of every partial measurement. See Chapter 5.1.4.1,
"Partial Measurements and Driving Mode", on page 84 .
"Meas Delay" is not available while a "Time" or "CW Mode" sweep is active.
As an alternative to increasing the delay (and thus the total sweep time), it is possible
to select "Alternated" driving mode; see "Driving Mode" on page 534.
