Commands required to export traces (and other result data) are described in Chap-
ter 14.9.5, "Storing Measurement Results", on page 1253.
FORMat[:DATA]........................................................................................................... 1142
TRACe<n>[:DATA]....................................................................................................... 1143
TRACe<n>[:DATA]:MEMory?.........................................................................................1144
TRACe<n>[:DATA]:X?...................................................................................................1145
FORMat[:DATA] <Format>[, <BitLength>]
This command selects the data format that is used for transmission of trace data from
the R&S FSW to the controlling computer.
Note that the command has no effect for data that you send to the R&S FSW. The
R&S FSW automatically recognizes the data it receives, regardless of the format.
For details on data formats see Chapter 14.8.2.5, "Formats for Returned Values: ASCII
Format and Binary Format", on page 1145.
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".
In the Spectrum application, 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.
64
64-bit floating-point numbers
Compared to REAL,32 format, twice as many numbers are
returned.
