Setting Up a DPX Density Trigger
The DPX Density trigger captures transients partially obscured by other higher-amplitude or more frequent signals. If you
can see it in the DPX bitmap, you can trigger on it. The DPX Density area measurement is used to select the region of
interest in the display and to measure its current density. You set a density threshold, and the instrument triggers when the
density measurement exceeds your threshold.
