Mode - HP 54501A Programming Reference Manual

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.
