Trigger Knobs and Buttons:
L EVEL – Selects the trigger threshold level
when the trigger signal is connected to the
Trigger input. The Level is indicated in the
Trigger
label.
S ETUP – Activates the trigger setup menu to
select the trigger type and the trigger
conditions.
S TOP – Prevents the scope from triggering on
a signal. If you boot up the instrument with the
trigger in Stop mode, the message "no trace
available" will be displayed.
A UTO – Acquires data in a free-running mode.
This allows viewing of a signal even though
trigger conditions are not net. The waveform is
unsynchronized in this mode and the CIS
timebase, if selected, will be unlocked.
N ORMAL – Sampling is controlled by the signal
applied to the trigger input: one sample per
edge of the trigger in SEQ timebase and one
sample per edge of the phase-locked clock in
CIS mode.
S INGLE – Acquires enough samples to fill the
selected memory length. This will generally
require hundreds to thousands of trigger
edges.
