What Is the Trigger (TRIG) BNC Used For?

The trigger BNC can be used to bring triggers into VirtualBench for use with the mixed signal oscilloscope or to export a trigger from VirtualBench, such as a function generator (FGEN) start signal. When importing a trigger, the mixed signal oscilloscope (MSO) can display the signal present on the TRIG BNC as a digital channel as well as use it as a trigger for the acquisition. When exporting a trigger, these options are available:

• A pulse is sent every time the FGEN begins a new period of the signal being generated.
• A pulse is sent every time the MSO triggers.
• A pulse is sent at the frequency of the 60 Hz/50 Hz AC line.
