A system that allows a programmer to insert instructions into a computer program that change criteria used by a logic analyzer to gather data. This criteria may include, a qualifier, which is used to filter data gathered by the logic analyzer, or a trigger condition that is used by the logic analyzer to decide when to take a snapshot of the data. This system opetates by configuring the logic analyzer to change its criterion for recording data when an instruction in the computer program is executed that communicates with the logic analyzer. The system additionally provides special programming language instructions, which communicate with the logic analyzer. By inserting the special instructions into a computer program, a programmer can select the criterion that the logic analyzer uses to gather date at key points in a computer program. This allows the programmer to specify how data is to be collected by the logic analyzer in different sections of code. Using this technique, a programmer can greatly reduce the amount of unnecesary data that is collected by the logic analyzer, and can thereby make better use of the limited data storage space available within the logic analyzer.
