CHANGE:
ADVANCED TRIGGER: Positive pulse ,
minimum 1. 7V from 50 ohm source typi—
cally 15 ms duration. Available on inter-
nally triggered operations only. Occurs
approx. 10% of the repetition rate period
before the reference trigger.
REFERENCE TRIGGER: Positive pulse,
minimum 2V from 50 ohm source, typi—
cally 15 ns duration. Occurs approx.
30 ns after triggering from an external
source.
