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 (±8192) 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 8192 is 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 (14 bit integer). Therefore the number of bytes
is always twice the number of data points.
Syntax
DATA:DAC VOLATILE, <start>，{<binary
block>|<value>, <value>, . . . }
Parameter

Example
DATA:DAC VOLATILE, #216 Binary Data
The command above downloads 5 data values
(stored in 14 bytes) using the binary block format.
