The subspan optimization modes "Dynamic" and "Auto" include automatic suppression
of unwanted mixing products. Thus, when using external mixers (R&S
FSV3-B21), use
the "Speed" mode to obtain similar results in FFT mode as in frequency sweep mode.
Zero span mode
For zero span measurements, the optimization mode defines the selection of the A/D
converter prefilter.
Table 12-6: Optimization parameters in zero span mode
Optimization mode
Description
DYNamic
The narrowest filter possible (depending on the RBW) is used.
SPEed
The widest filter possible (depending on the RBW) is used.
AUTO
A medium-sized prefilter is used.
Note: EMI measurements
For EMI measurements (using R&S
FSV3-K54), "Dynamic" mode is not supported.
"Auto" mode always uses "Speed" optimization.
Parameters:
<Mode>
*RST:
AUTO
Example:
SWE:OPT DYN
Selects optimization for dynamic range.

This command defines the number of sweep points to analyze after a sweep.

[SENSe:]SWEep:TIME
<Time>
This command defines the sweep time. It automatically decouples the time from any
other settings.
In the Spectrum application, the command decouples the sweep time from the span
and resolution and video bandwidths. Note that this command queries only the time
required to capture the data, not to process it. To obtain an estimation of the total cap-
ture and processing time, use the
command.
