Remarks
In the NORMal byte order (default) the most-significant byte (MSB) of each
data point is assumed first.
In the SWAPped byte order the least-significant byte (LSB) of each data
point is assumed first. Most PCs use the "swapped" byte order.
The byte order setting is stored in non-volatile memory and does not
change when power has been off. The default value will be restored after a
Factory Reset (*RST command), or after an Instrument Preset
(SYSTem:PRESet command).
