Each data value requires two to seven characters. This includes one character

for the minus sign if the value is negative, one to five ASCII characters for

the waveform value, and a comma to separate data points.

An example of an ASCII waveform data string follows:

CURVE<space>-110,-109,-110,-110,-109,-107,-109,-107,

-106,-105,-103,-100,-97,-90,-84,-80

■

Binary data can be represented by signed integer or positive integer values.

The range of the values depends on the byte width specified.

Table 25: 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

part 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 instrument 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 500th point in

the record. The instrument ignores DATa:STOP when reading in data as the

instrument 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 instrument to an external device. Setting DATa:STARt

to 1 and DATa:STOP to 2500 always sends the entire waveform, regardless of

the acquisition mode.
