SOURce[1]:FUNCtion USER
Source Specific
Command
Description Use the SOURce[1]: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]: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 (±32767) 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 32767is 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:
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.
