Tables 7-19
and
7 -20 illustrate 8-bit
and
16-bit
HEXadecimal-encoded waveform-data transfers.
ASCII Encoding
With ASCII waveform data encoding, ASCII characters
representing the binary value of
each
waveform data point
are
sent
in
variable length format, separated
by
commas.
In
ASCII format, the curve data transfer
is
represented
as:
CURVE< space> data,data,data, ..... ,data
<terminator>

Table
7-21
illustrates
an
8-bit ASCII-encoded waveform
transfer. Transmission length depends
on
specific
waveform data values, record length, acquisition mode
and
smoothing,
and
whether the acquisition
is
one
or two
channels.
