Waveform Data Formats
Internally, the oscilloscope uses one 8-bit data byte to represent each
waveform data point, regardless of the acquisition mode.
The DATa:WIDth command lets you specify the number of bytes per
data point when transferring data to and from an oscilloscope. This
provides compatibility with other digitizing oscilloscopes.
When DATa:WIDth is set to two:
H If sending data, the oscilloscope multiplies each point by 256; t he
most significant byte then has meaningful data and the least
significant byte is 0
H If receiving data, the oscilloscope truncates the data (divides by
256) and saves the most significant byte
NOTE. The oscilloscopes uses these methods to handle waveforms
transmitted in ASCII or binary format.
