Logic analyzer.

摘要

A logic signal analyzer comprises a time measuring adapter. Only some of the input channels of the signal analyzer are used to store input data when an event occurs, i. e. when one or more of the binary input signals change their value. A time counter (7) is provided for measuring the time that has elapsed between two consecutive events. The contents of the time counter are transferred to the logic analyzer on the remaining input channels.
<??>In another mode of operation only the signal on a predetermined input channel is used to control the storing operation. The time counter is reset after each storing operation.
<??>In still another mode of operation the signal on a predetermined channel can be used to inhibit or allow the storing of the signals on the remaining input channels.
