values range from 0 to 255. When the byte width is two, the signed integer data
ranges from --32768 to 32767, and positive integer values range from 0 to
65,535.

The defined binary formats also specify the order in which the bytes are
transferred. The four binary formats are RIBinary, RPBinary, SRIbinary, and
SRPbinary.
RIBinary is signed integer where the most significant byte is transferred first,
and RPBinary is positive integer where the most significant byte is transferred
first. SRIbinary and SRPbinary correspond to RIBinary and RPBinary respec-
tively but use a swapped byte order where the least significant byte is transferred
first. The byte order is ignored when DATa:WIDth is set to 1.
You can transfer multiple points for each waveform record. You can transfer a
portion of the waveform or you can transfer the entire record. The DATa:STARt
and DATa:STOP commands let you specify the first and last data points of the
waveform record.
The oscilloscope supports 2 waveform record lengths: 500 points and 10,000
points. When transferring data into the oscilloscope, you must first specify the
record length of the destination waveform record. This is done with the
WFMPre:NR_Pt or WFMPre:REF<x>:NR_Pt commands. Next, specify the first
data point within the waveform record. For example, when you set DATa:STARt
to 1, data points will be stored starting with the first point in the record, and
when you set DATa:STARt to 500, data will be stored starting at the 500
th
point
in the record. The oscilloscope will ignore DATa:STOP when reading in data as
it will stop reading data when it has no more data to read or when it has reached
the specified record length.
When transferring data from the oscilloscope, you must specify the first and last
data points in the waveform record. Setting DATa:STARt to 1 and DATa:STOP
to the record length will always return the entire waveform.
The DATa:SOUrce command specifies the waveform source when transferring a
waveform from the oscilloscope. You can only transfer one waveform at at time.
You can transfer in to the oscilloscope one waveform at a time. Waveforms sent
to the oscilloscope are always stored in one of the four reference memory
