Table 2−22: Binary data ranges
Byte width Signed integer range Positive integer range
1 –128 to 127 0 to 255
2 –32,768 to 32,767 0 to 65,535
The defined binary formats also specify the order in which the bytes
are transferred giving a total of four binary formats: 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 respectively 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.
Waveform Data Record
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.
When transferring data into the oscilloscope you must specify the
location of the first data point within the waveform record. For
example, when DATa:STARt is set to 1, data points will be stored
starting with the first point in the record, and when DATa:STARt is
set to 500, data will be stored starting at the 500
th
point in the record.
The oscilloscope ignores DATa:STOP when reading in data as the
oscilloscope will stop reading data when there is no more data to
read or when it has reached 2500 data points.
You must specify the first and last data points in the waveform
record when transferring data from the oscilloscope to an external
device. Setting DATa:STARt to 1 and DATa:STOP to 2500 always
sends the entire waveform, regardless of the acquisition mode.
