Trigger on spe
cified fields or lines of a composite video
signal. Only composite signal formats are supported.
Trigger on NTSC, PAL, or SECAM. Works with
Macrovision s
ignals.
With the D PO4VID module, trigger on a variety of HDTV
video standard signals, as well as custom (non-standard)
bilevel and t
rilevel video signals with 3 to 4,000 lines.

Triggering on Buses
You can use y our oscilloscope to trigger on multiple data buses, if you have the appropriate application module installed. The
MDO4000 Series can trigger on parallel buses without an application module. The oscilloscope can display both the physical
layer (as analog waveforms) and the protocol level information (as digital and symbolic waveforms).
To set u p the bus trigger:
1. If you have not already defined your bus
using the front-panel B1, B2, B3,orB4
buttons, do so now. (See page 60, Setting
Up a Serial o r Parallel Bus.)
