Record Length
Defines the number of I/Q samples to record. By default, the number of measurement
points is used. The record length is calculated as the measurement time multiplied by
the sample rate. If you change the record length, the
changed, as well.
Note:
For the I/Q vector result display, the number of I/Q samples to record ("Record
Length") must be identical to the number of trace points to be displayed ("Sweep
Points"). Thus, the measurement points are not editable for this result display. If the
"Record Length" is edited, the measurement points are adapted automatically.
For record lengths outside the valid range of measurement points, i.e. fewer than 101
points or more than 100001 points, the diagram does not show valid results.
Remote command:
RBW
Defines the resolution bandwidth. The maximum RBW corresponds to the
. The minimum RBW depends on the sample rate.
Depending on the selected RBW mode, the value is either determined automatically or
can be defined manually. As soon as you enter a value in the input field, the RBW
mode is changed to "Manual".
If the "Advanced Fourier Transformation Params" option is enabled, advanced FFT
mode is selected and the RBW cannot be defined directly.
Note that the RBW is correlated with the
). Changing any one of these parameters
may cause a change to one or more of the other parameters.

"Auto mode"
(Default) The RBW is determined automatically depending on the
.
"Manual mode" The RBW can be defined by the user. The maximum RBW corre-
. The minimum RBW depends on
the sample rate.
The user-defined RBW is used and the
"Advanced
FFT mode"
This mode is used if the "Advanced Fourier Transformation Params"
option is enabled.
The RBW is determined by the

Remote command:
Advanced FFT mode / Basic settings
Shows or hides the "Advanced Fourier Transformation" parameters in the "Data Acqui-
sition" dialog box. These parameters are only available and required for the advanced
FFT mode.
