HP 54501A - Digitize

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.
