SOURce[1|2]:FUNCtion USER
Source Specific 
Command 
Description
Use the SOURce[1|2]:FUNCtion USER command 
to output the arbitrary waveform currently 
selected in memory. The waveform is output with 
the current frequency, amplitude and offset 
settings. 
Syntax
SOURce[1|2]:FUNCtion USER
Example
SOUR1:FUNC USER
Selects and outputs the current waveform in 
memory. 
DATA:DAC
Source Specific 
Command 
Description
The DATA:DAC command is used to download 
binary or decimal integer values into memory 
using the IEEE-488.2 binary block format or as an 
ordered list of values. 
Note
The integer values (±511) correspond to the 
maximum and minimum peak amplitudes of the 
waveform. For instance, for a waveform with an 
amplitude of 5Vpp (0 offset), the value 511is the 
equivalent of 2.5 Volts. If the integer values do not 
span the full output range, the peak amplitude will 
be limited. 
The IEEE-488.2 binary block format is comprised 
of three parts: 
# 7 2097152
2
1
3
1. Initialization character
(#)
2. Digit length (in ASCII) of
the number of bytes
3. Number of bytes
IEEE 488.2 uses two bytes to represent waveform
