Oscilloscope Reference ACos
Mathcad. This creates (.dat) files in a format usable by MathCad. The MathCad file is an ASCII file,
the first five values of which contain the following header information:
The first header v alue holds the record length.
The second header value holds time, in seconds, between samples.
The third header value holds the trigger position (expressed as an index in the data position).
The fourth header value refers to the fractional trigger position.
The fifth hea
der value holds the horizontal offset in seconds.
NOTE. The delimiters are carriage returns.

Acqu
isition interval
The
acquisition interval is the time between sample points. For mathematical purposes, it is the time
covered by the waveform record divided b y the record length.
Ac
quisition window
T
he acquisition window defines what data are sampled from the input signal to form a waveform record.
The vertical scale and offset controls set the vertical size and vertical center of this window
independently for each channel.
The horizontal scale and position controls set the horizontal size and position for all channels in unison.
