Cross-Triggering
Cross-Triggering
An instrument must be armed before it can look for a trigger. By
default, instruments are set to be armed immediately when you Run
the measurement.
However, you can set an analyzer instrument to be armed either by the
second analyzer within the same instrument (if it's turned on) or by
another instrument (in a different slot or frame).
