download seven integer points using the binary block format (see also “Using
the IEEE-488.2 Binary Block Format” below).

– 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:
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, 16,384 bytes are required to download a waveform with 8,192 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.
