12.2.1.2 Waveform data files
The waveform data files - indicated by *Wfm.* in the filename - contain the actual
waveform data. Usually only Y-values - mostly voltage values - are written subse-
quently
. If the signal is a spectrum, the data of the last frame is written.
If the waveform consists of minimum and maximum values, two Y-values per sample
are written, and the property InterleavedTraceCount in the header file is >1. This
applies to envelope waveforms, for example.
The option "Interleaved X/Y" allows you to include horizontal values into the file.
If multi-channel export is enabled, the Y-values of the selected channels are written in
interleaved order.
