Autoscale - HP 54501A Programming Reference Manual

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.
