Logic trigger

The PicoScope oscilloscope software offers a wide range of simple and advanced triggers for detecting and capturing elusive signals. Most of these trigger types are capable of monitoring only one signal at a time. Since many oscilloscopes have more than one input—up to eight channels as well as an EXT or AUX input on some models—PicoScope provides a special ‘Logic’ trigger type that can watch for combinations of up to four inputs.

The simplest way to monitor multiple inputs is to trigger when any one of them meets a specified condition. However, there are applications that require a more selective approach. For example, we might want to detect when both inputs meet specified conditions at the same time. PicoScope solves this problem by offering a list of logical functions for combining inputs.

If you plug in a PicoScope mixed-signal oscilloscope (MSO), the software will provide another triggering type called ‘Digital’. This behaves as a separate input to the Logic trigger function. For further information on the MSO Logic trigger, see the PicoScope 6 User’s Guide.
