HP 54501A - Mode

MODE
MODE
command/query
The
:TIMEBASE:MODE
command
selects
the
timebase
mode.
This
function
is
the
same
as
the trigger
menu
Auto/Trig'd
key
and
the SINGLE
key
on
the
front
panel.
If the
AUTO
mode
is
selected,
the unit
will provide
a
baseline
on
the
display
in
the
absence
of
a signal.
If
a signal
is
present
but
the
oscilloscope
is
not
triggered, the
display will
be
unsynchronized
but
will
not
be
a
baseline.
If
the
TRIGGERED
mode
is
selected
and
no
trigger
is
present,
the
unit
will
not
sweep,
and the
data
acquired
on
the
previous trigger will
remain
on screen.
If the
SINGLE
mode
is
selected
the
screen
will
be
cleared and
the
instrument
will
be
stopped.
The
RUN
command
will
arm
the trigger,
then
data
will
be
acquired
when
the
trigger
is
found.
To make
a
single
acquisition
a
RUN
command
should
be
sent.
The
MODE
query
returns
the
current
mode.
