FORMat[:DATA] <Format>[, <BitLength>]
This command selects the data format that is used for transmission of trace data from
the R&S FSWP to the controlling computer.
Note that the command has no effect for data that you send to the R&S FSWP. The
R&S FSWP automatically recognizes the data it receives, regardless of the format.
Parameters:
<Format> ASCii | REAL | UINT | MATLab
ASCii
ASCii format, separated by commas.
This format is almost always suitable, regardless of the actual
data format. However, the data is not as compact as other for-
mats may be.
REAL
Floating-point numbers (according to IEEE 754) in the "definite
length block format".
The format setting REAL is used for the binary transmission of
trace data.
<BitLength>
16 | 32 | 64
Length in bits for floating-point results
16
16-bit floating-point numbers.
Compared to REAL,32 format, half as many numbers are
returned.
32
32-bit floating-point numbers
For I/Q data, 8 bytes per sample are returned for this format set-
ting.
