SAVe:WAVEform:FILEFormat
Description
This command specifies or returns the file format for saved waveforms.
Waveform header and timing information is included in the resulting
file of non--internal formats. The instrument saves DPO waveforms as a
500 x 200 matrix, with the first row corresponding to the most recently
acquired data. The values specified by DATa:STARt and DATa:STOP
determine the range of waveform data to output. In the event that
DATa:STOP value is greater than the current record length, the current
record length determines the last output value.
This command is equivalent to selecting Save As from the File menu,
clicking the Waveform button, and choosing the desired waveform file
format from the Save as type drop --down list.

Arguments
H INTERNal
This specifies that waveforms are saved in an internal format, using a
.wfm filename extension. These files can be recalled as reference wa-
veforms. When this argument is specified, the settings specified via
the DATa:STARt and DATa:STOP commands have no meaning as the
entire waveform is saved.
H MATHCad
This specifies that waveforms are saved in MathCad format, using a
.dat filename extension. When saving in this format, waveform values
are delimited with new lines. MathCad format enables easy import of
waveform data into MathCad or MATLAB.
For FastAcq waveforms, data is imported as a matrix. For these for-
mats, waveform header and timing information is saved in a separate
header file. MathCad format header files use a _hdr.dat extension.
