Patent ID: 8024141

Claim:
A test and measurement instrument, comprising: an input terminal to receive a signal under test; one or more analog-to-digital converters associated with the input terminal, the one or more analog-to-digital converters to receive the signal under test and to produce digital samples from the signal under test; an acquisition memory to store the digital samples of the signal under test as a data record; a display device associated with the signal under test; a first trigger circuit having an input coupled to the input terminal, the first trigger circuit to detect a live trigger event in the signal under test based on first trigger criteria and to cause an automatic adjustment of a waveform to conform with a time of the live trigger event; a second trigger circuit to detect one or more post-acquisition trigger events in the data record based on second trigger criteria, wherein the display device is configured to adjust a display of the one or more post-acquisition trigger events and a waveform associated with the data record responsive to one or more configurable trigger controls.
