Capturing Random Events

ĂĂStep 8:ă
Check that the sweep triggers each time the
INIT
button
is pressed. If it does not, readjust the trigger level control slightly
until the sweep triggers each time you press
INIT
. The
TRIG'D
indicator lights when the instrument triggers.
ĂĂStep 9:ă
Disconnect the test signal from the oscilloscope and
apply the random signal to the input.
ĂĂStep 10:ă
Press
INIT
to arm the trigger system. The instrument
then waits for the trigger event. The
TRIG'D
indicator lights when
the instrument triggers.
ĂĂStep 11:ă
After the instrument triggers and completes the single
sequence, press
INIT
again to acquire another signal.
In scroll mode, the singleĆsequence trigger mode is useful for capturĆ
ing an event that occurs either randomly or infrequently. If the event is
also very narrow, use the envelope mode as well.
Initialize the singleĆsequence function and let the oscilloscope watch
for the event. The 222PS acquires data continuously up to the trigger
point. When the trigger event occurs, the instrument acquires the data
it needs to fill the rest of the display. It then halts the acquisition and
displays the waveform (with the captured trigger event) until you press
the
INIT
button again.
