These controls allow direct adjustment of time/division,
trigger level and delay, and access the “TIMEBASE” and
“TRIGGER” menu groups.
$8726(783 The blue button
automatically scales
the timebase, trigger
level, offset, and
volts/div to provide a
stable display of
repetitive signals.
AUTO SETUP operates only on
channels which are active. If no
channels are on, then AUTO
SETUP will operate on all
channels, switching them all on.
Signals detected must have an
amplitude between 5 mV and
40 V, a frequency greater than
50 Hz, and a duty cycle greater
than 0.1 %.
If signals are detected on several
channels, the channel with the lowest number will determine the
selection of the timebase and trigger source.

$872 Pressing this button places the instrument in Auto Mode: the
scope automatically displays the signal if
60 ms.
If a trigger does occur within this time, the osc illoscope behaves
as in Normal Mode.
Press AUTO in RIS Mode and the ac quisition will be terminated
and shown each second (some required segments may be
missing).
Press the button in Roll Mode and the oscilloscope will sample
the input signals continuously and indefinitely. The acquisition will
have no trigger condition but can be stopped as desired.
Press AUTO in Sequence Mode and the acquisition will be
terminated if the tim e between two consecutive triggers exceeds
a timeout that can be selected. The next acquisition is then

1250 Pressing this button will continuously update the screen as long
as a valid trigger is present. If not, the last signal is preserved
and the warning “SLOW TRIGGER” is displayed in the Trigger
Status Field.
Press NORM in Roll Mode and the acquisition will be terminated
when the last needed data after a trigger have been taken. The
display will pause to show the entire waveform. It then goes back
into Roll Mode while it waits for the next trigger.
Press this button in Sequence Mode and the acquisition will be
terminated after the last segment is acquired. The next
acquisition will start imm ediately. Sequence WRAP in Norm al is
the same as in Single-Shot Mode.
