• The following statement shows how to use the DATA:DAC command to
download five integer points in decimal format.

Using the IEEE-488.2 Binary Block Format
In the binary block format, a block header precedes the waveform data.
The block header has the following format:
#532768
The function generator represents binary data as 16-bit integers, which
are sent as two bytes. Therefore,
the total number of bytes is always
twice the number of data points in the waveform
(and must always be an
even number). For example, 32,768 bytes are required to download
a waveform with 16,384 points.
Use the FORM:BORD command to select the byte order for binary
transfers in block mode. If you specify FORM:BORD NORM (default),
the most-significant byte (MSB) of each data point is assumed first.
If you specify FORM:BORD SWAP, the least-significant byte (LSB) of
each data point is assumed first. Most computers use the “swapped”
byte order.
