Return values:
<SweepPointValues>
Example:
Usage:
TRACe<n>[:DATA]:X? <TraceNumber>
This command queries the horizontal trace data for each sweep point in the specified
window, for example the frequency in frequency domain or the time in time domain
measurements.
For more information, see
This is especially useful for traces with non-equidistant x-values, e.g. for SEM or Spuri-
ous Emissions measurements.

Formats for returned values: ASCII format and binary format
When trace data is retrieved using the TRAC:DATA or TRAC:IQ:DATA command, the
data is returned in the format defined using the
possible formats are described here.
●
ASCII Format (FORMat ASCII):
The data is stored as a list of comma-separated values (CSV) of the measured val-
ues in floating point format.
●
Binary Format (FORMat REAL,16/32/64):
The data is stored as binary data (definite length block data according to IEEE
488.2), each measurement value being formatted in 16-bit/32-bit/64-bit IEEE 754
floating-point-format.
The schema of the result string is as follows:
#<Length of length><Length of data><value1><value2>...<value n>
