When Extended-Acquisition-Length mode is on, the convention is to use a .wf1

If you are writing a MathCad program, you should be aware that the
TDS-MathCad file has the following features:
TDS-MathCad file has the following features:
H ASCII format
H first four values contain header information
H first header value holds the TDS waveform record length
H second header value holds time, in seconds, between samples
H third header value holds the trigger position
(expressed as an index in the data position. For extended-acquisition-length
records, the index reported can be outside the waveform because the trigger
can be outside the waveform. If before the waveform, it’s negative. If after,
it’s a large positive)
records, the index reported can be outside the waveform because the trigger
can be outside the waveform. If before the waveform, it’s negative. If after,
it’s a large positive)
H fourth header value refers to the fractional trigger position
H delimiters are carriage returns
