Internal data arrays
Corrected data arrays
A corrected data array contains the corrected data obtained by performing error correction,
port extension compensation (calibration), Fixture Simulator operations on the raw
measured data of S parameter specified for each trace of each channel. Each data element
is stored as a complex number (Re/Im).
The instrument retains 16 corrected data arrays at maximum, each of which is associated
with one of the 4 traces contained in one of the 4 channels 4×4 = 16). To read/write one of
the corrected data arrays, use the following command:
• :CALC{1-4}:DATA:SDAT on page 217
Corrected memory arrays
When the :CALC{1-4}:MATH:MEM command on page 281 command is executed on a
particular corrected data array, its copy is stored into the corrected memory array
corresponding to that corrected data array.
The instrument retains 16 corrected memory arrays at maximum, each of which is
