Waveform Commands
Description
Use
as
a command to send waveform data to the oscilloscope. The DATa
TAR get command points
to
the reference memory where the data
is
sent. The
DATa CHAnnel command points to the channel where the data
is
sent. (Only
REF4
is
available for the 2220
and
2221.) The DATa
ENCdg
command tells the
oscilloscope the format
of
the data
(HEX,
BINary, or ASCii).
Use
as
a query to get waveform data from the oscilloscope. The DATa
source
and
DATa CHAnnel commands select the source of the waveform data.
The data sent or received
is
in
the form:
CURVE
<data>;
where the
<data>
is
encoded for
HEX,
BINary, or ASCii
in
the following form:
%<byte
count>
<binary
data>
<checksum>
for BIN,
#H<byte
count><hex
data><checksum>
for
HEX,
or
<ascii
data>
for ASCii encoding.
With ASCii format, each data value
is
separated
by
a comma.
Selects the channel of a waveform set from which CURve?, WAVfrm?, or
WFMpre? query will return data
and
the target channel for waveform data going
into oscilloscope.
If there
is
no waveform
in
the named channel, a service request
is
sent when the
data
is
requested. - -
At power-up, the selected channel
is
CH1.
CH1
must
be
selected for
an
XY
acquisition.
Sets the curve data encoding
and
decoding format.
The
power-on default
is
BINary. Data points are represented
as
unsigned integers
in
all
formats.
