The Trigger Out connector
Each time the oscilloscope triggers, a rising edge is output at the
TRIG OUT connector on the rear panel of the oscilloscope. This
rising edge is delayed 17 ns from the oscilloscope’s trigger
point. The output level is 0-5 V into an open circuit, or 0-2.5 V
into 50 Ω.
The Trigger Out connector also provides the User Cal signal. See “User
Calibration” on page 82.
