Digitize - HP 54501A Programming Reference Manual

DIGitize
DIGitize command
The
DIGITIZE
command
is used to acquire waveform data for transfer
over
the
HP-IB. It
causes
an acquisition to take place on the specified
channel(s) with the resulting data being placed in the channel buffer.
The
ACQUIRE
subsystem commands are used to
set up conditions such
as
TYPE,
number of POINTS,
and the
COUNT
for the
next
DIGITIZE
command. See the
ACQUIRE
subsystem for
a
description
of
these
commands.
To
determine the actual number of points that are acquired
and how the data will be transferred,
refer
to the
WAVEFORM
Subsystem commands.
For
more information on the
DIGITIZE
command refer to
the section on the
DIGITIZE
command
in the chapter
"Introduction to Programming an
Oscilloscope."
Note
Sending
the
DIGITIZE
command will
turn
off
any
unused
channels.
When the Digitize operation
is
complete the instrument
is placed in
the
stopped mode.
When the instrument
is restarted, with
a
RUN
command
or the front panel RUN
key,
the digitized data
stored in the channel
buffers will be overwritten.
Therefore,
ensure all operations that
require
the
digitized data are completed before restarting the HP
54501A.
The
speed
of
the total digitize operations may be improved if
two or more
DIGITIZE
commands are sent
without changing other parameters.
The
sources
for
the
:DIGITIZE
command are channels
1 through 4.
