{REAL | COMP}
Description
In Oscilloscope and Eye Mask modes, selects the kind of data values, real (REAL
) or complex (COMPlex
), to save in a VSA Waveform Recording file. The default setting is COMPlex
. When COMPlex
is selected, a second signal source must be selected using the :DISK:WAVeform:SAVE:VSA:QSOUrce
command. Use the :DISC:WAVeform:SAVE
command to actually save the file.
The VSA expects either real or complex data. Real data is only composed of one data part and uses a single bus. Complex data can be expressed as I/Q pairs (or magnitude/phase) with each data part using a separate bus or both parts interleaved using a single bus. For real data, there is one value per line in the file. For complex data, there are two entries per line in the file. The first entry being the real value and the second entry being the data point's imaginary value.
