Binary data ca
n b e represented by signed integer or positive integer values.
The range of the values depends on the byte width specified.
Table 2-29: 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 b inary 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 or
der 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
part of the waveform or you can transfer the entire record. The DATa:STARt
and D
ATa:STOP commands let you specify the first and last data points of the
waveform record.
Whe
n 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 w ill 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
h
as 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.
Waveform Data Locations
and Memory Allocation
The DATa:SOUrce command specifies the location of the data when transferring
waveforms from the oscilloscope. You can transfer one waveform at a time.
You can transfer only one waveform into the oscilloscope at a time. Each
waveform is stored in one of two stored waveform locations for 2-channel models
or one of four stored waveform locations for 4-channel models. You specify the
stored waveform location with the DATa:DESTination command.
