If enabled, the required number of samples are inserted as zeros at the beginning and
end of the file. The entire input data is analyzed. However, the additional zeros can
effect the determined spectrum of the I/Q data. If zero padding is enabled, a status
message is displayed.
If disabled (default), no zeros are added. The required samples for filter settling are
taken from the provided I/Q data in the file. The start time in the R&S
VSE
Player is
adapted to the actual start (after filter settling).
Note:
You can activate zero padding directly when you load the file, or afterwards in
the "Input Source" settings.

Center Frequency
Defines the center frequency of the signal in Hertz.
0 Hz ≤ f
center
≤ f
max
Note:
For file input, you can shift the center frequency of the current measurement
compared to the stored measurement data. The maximum shift depends on the sam-
ple rate of the file data.
If the file does not provide the center frequency, it is assumed to be 0
Hz.
In order to ensure that the input data remains within the valid analysis bandwidth,
define the center frequency and the analysis bandwidth for the measurement such that
the following applies:
