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 num-
ber 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 (= 4 in the example) of the following number
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,16 is 2
32
- 1.
For data conversion, you need the results of following commands:
...: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 15.3.1.2, "Reading
Waveform Data in Unsigned Integer Format", on page 458.
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).
