INTERNal specifies the internal format. Internal format files usually have a .wfm
extension.
When Extended-Acquisition-Length mode is on, the convention is to use a .wf1
extension. Also, the oscilloscope will only use this internal format with this
mode.
SPREADSheet specifies the spreadsheet format. Spreadsheet format files usually
have a .CSV extension.
MATHCad specifies the MathCad format. MathCad format files usually have a
.DAT extension.
If you are writing a MathCad program, you should be aware that the
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)
H fourth header value refers to the fractional trigger position
H delimiters are carriage returns
SAVE:WAVEFORM:FILEFORMAT SPREADSHEET
specifies the waveform, when saved, will be stored in a spreadsheet-compatible
format.
