15. Press SET LEVEL TO 50%. Check that a stable trigger is obtained for the
test waveform on both the positive and negative slopes (see Figure B–7).
(Use the side menu to switch between trigger slopes; use the trigger LEVEL
knob to stabilize the trigger if required.)
First, set a signal with an
amplitude at the minimum trigger
sensitivity.
Second, check for a stable
trigger at both the positive and
negative slope settings.
