Abstract
A method and apparatus enabling the analog and digital triggering of a signal analysis device such as a Logic Analyzer, wherein separate analog and digital signal paths provide separate analog and digital processing of an input test signal for enabling the triggering of a signal analysis device upon analog and digital signal conditions.
Claims19
A test and measurement instrument, comprising:
- an input conductor for receiving input test signals from a device under test, said input test signals being directed in parallel to a digital path and an analog path;
- said digital path processing said input test signals to create a digital representation of said input test signals;
- said analog path processing said input test signals to create an analog representation of said input test signals;
- a digital trigger circuit coupled to said digital path for evaluating said processed digital signals for preset digital conditions and generating a digital control trigger upon detection of said preset digital conditions;
- and
- an analog trigger circuit coupled to said analog path for evaluating said processed analog signals for preset analog conditions and generating an analog control trigger upon detection of said preset analog conditions.

A method, comprising:
- processing an input test signal to create a digital representation of said input test signal;
- processing said input test signal to create an analog representation of said input test signal;
- generating a digital trigger in response to said digital representation favorably comparing to at least one preset digital condition;
- and
- generating an analog trigger in response to said analog representation favorably comparing to at least one preset analog condition.
