Video
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 DPO3VID m odule, 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.
Bus Trigger on v
arious bus conditions.
Parallel requires an MSO3000 Series oscilloscope.

C and SPI requires a DPO3EMBD module.
RS-232, RS
-422, RS-485, and UART require a
DPO3COMP module.
MIL-STD-1553 requires a DPO3AERO module.
CAN and LIN
requires a DPO3AUTO module.
FlexRay requires a DPO 3FLEX module.
I

S, Left Justified (LJ), Right Justified (RJ), and TDM
require a
DPO3AUDIO m odule.

S, Left Justified (LJ), Right Justified (RJ), and TDM buses, if you have the appropriate DPO3AERO, DPO3AUDIO,
DPO3AUTO, DPO3COMP, DPO3EMB D, or DPO3FLEX application m odule installed. The MSO3000 Series can trigger
on parallel buses without an application module. The oscilloscope can display both physical layer (as analog waveforms)
and protocol level information (as symbolic waveforms).
To set up the bus trigger:
1. If you have not already defined your bus
using B1 and B2 on the front-panel, do so
now. (See page 54, Setting Up a Serial or
Parallel Bus.)
2. Push Trigger Menu.
