Dual Arbitrary Waveform Generator

Using Waveform Markers

Waveform Marker Concepts

The Dual Arb mode of the signal generator has four markers that you can place on a waveform segment. Marker 1 and Marker 2 provide auxiliary output signals to the rear-panel EVENT 1 and EVENT 2 connectors, respectively. Markers 3 and 4 are available only for custom-programmed waveforms, and they provide auxiliary output signals to pins 19 and 18 of the rear-panel AUXILIARY I/O connector, respectively. You can construct these output signals as a trigger signal to synchronize another instrument to a given portion of a waveform. The following timing diagrams describe the effects of Markers 1 and 2 on the state of the signal at the EVENT 1 and EVENT 2 rear panel connectors.
