8-16-2. SOURce[1|2]:FUNCtion USER
Set
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.
8-16-3. SOURce[1|2]:DATA:DAC
Set
Description The SOURce[1|2]: 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 data (16 bit
integer). Therefore the number of bytes is always twice the
number of data points.
