ABSTRACT:
A method of detection of metastability of a trigger in a digital storage oscilloscope compares a predetermined address used to produce a trigger ready signal with a current address determined by the occurrence of a trigger event after the trigger ready signal. If the difference between the two addresses is within a predetermined limit, a metastable condition is indicated, and data acquired is treated as corrupted data.
