Remote command:
[SENSe<Ch>:]SWEep:POINts
Freq Step Size
Sets the distance between two consecutive sweep points of a linear frequency sweep.
For linear frequency sweeps the step size is an alternative to the Number of Points
setting:
●
If the sweep range is defined via "Start Frequency" and "Stop Frequency", both the
"Stop Frequency" value and the "Number of Points" can vary as the "Freq Step
Size" is changed. The "Stop Frequency" value is changed as little as possible so
that the condition
"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.
