HP 54501A - Autoscale

AUToscale
AUToscale
command
The
AUTOSCALE
command causes
the
oscilloscope
to evaluate
all input
signals
and
set
the
correct
conditions
to
display
the
signals.
When
the
AUTOSCALE
command
is
sent
the
following
conditions
are
set:
the
vertical
sensitivity,
the
vertical
offset;
the
trigger
to
edge
mode
with
minimum
persistence;
the
trigger
level,
holdoff,
and
slope;
and
the
sweep
speed
of the
displayed
channel.
In addition,
the
AUTOSCALE
command turns
off:
markers;
all
measurements;
functions;
windows;
memories; and
connect
the
dots.
If
input
signals
are
present
on more
than
one
vertical
input,
the
sweep
will
be
triggered
on
channel
1
if
a
signal
is
present
on
that
channel.
If
a
signal
is
not
present
on
channel
1
then
the
oscilloscope
will
be
triggered
on
channel
4
if
a
signal
is
present
on
that
channel.
If
a
signal
is
not
present
on
channel
4
then
the
oscilloscope will
be
triggered
on
channel
2 if
a
signal
is
present
on
that
channel,
or
on
channel
3
if
no
other
signals
are
found.
If
no
signals
are
found
on any
vertical
input,
the
oscilloscope
is
returned
to
its
former
state.
