Parameters:
<DataFormat> ASCii | REAL | UINTeger
ASCii
List of values, for example, 1.23,1.22,1.24,..
<Accuracy> is 0 which means that the instrument selects the
number of digits to be returned. The query returns ASC,0.
REAL
Binary format. <Accuracy> is 32. The query returns REAL,32.
The data is stored as binary data (Definite Length Block Data
according to IEEE 488.2). Each waveform value is formatted in
32 Bit IEEE 754 Floating-Point-Format.
The schema of the result string is as follows:
#41024<value1><value2>…<value n> with:
#4 = number of digits of the following number (= 4 in the exam-
ple)
1024 = number of following data bytes (= 1024 in the example)
<value> = 4-byte floating point values
UINTeger
Unsigned integer format, binary values with length 8 bit (1 byte
per sample), 16 bit (2 bytes per sample) or 32 bit (4 bytes per
sample): UINT,8 or UINT,16 or UINT,32.
The data range for UINT,8 is 0 to 255, the data range for
UINT,16 is 0 to 65.535 and for UINT,32 is 2
32
- 1.
The schema of the result string is the same as for REAL format.
For data conversion, you need the results of following com-
mands:
...:DATA:XORigin?; ...:DATA:XINCrement?; ..:DATA:
Yorigin?; ...:DATA:YINCrement?; ...:DATA:
YRESolution?. They are described below in this chapter. The
way of data conversion is described in
Chapter 15.2.1.4, "Read-
ing Waveform Data in Unsigned Integer Format"
, on page 243.
32 bit data is relevant for average waveforms if averaging 512 or
1024 waveforms. The resulting data is 17 bits long (512 wave-
forms) or 18 bit (1024 waveforms).
