Oscilloscope Reference Set to 50% with Comm triggers
Set to 50% with Comm triggers
Push the front-panel Level knob.
Overview
The Set to 50% control sets the trigger threshold to 50% for some Comm triggers, and to a high of 75%
with a low of 25% for others.
Behavior
When either AMI or MLT-3 code is selected with Comm triggers the Set 50% control measures
peak-to-peak level and sets an upper threshold value at 75% and a lower threshold value at 25%. Other
codes work exactly the same as Edge, Width, Glitch, and Timeout triggers;
the threshold is set to 50%.
