Visual Trigger – Find the signal of interest quickly

Finding the right cycle of a complex bus can require hours of collecting and

sorting through thousands of acquisitions for an event of interest. Defining a

trigger that isolates the desired event speeds up debug and analysis

efforts.

Visual Trigger qualifies the Tektronix Pinpoint Triggers by scanning through

all waveform acquisitions and comparing them to on-screen areas

(geometric shapes). Up to eight areas can be created using a mouse or

touchscreen, and a variety of shapes (triangles, rectangles, hexagons, or

trapezoids) can be used to specify the desired trigger behavior. Once

shapes are created, they can be edited interactively to create ideal trigger

conditions

Visual Trigger extends the Tektronix oscilloscope's triggering capabilities

for a wide variety of complex signals as illustrated by the examples shown

here.

Customized serial triggering. Visual Trigger set to find a serial data pattern of 1101 0101.

Multiple channel triggering. Visual Trigger areas can be associated with events spanning

multiple channels such as packets transmitted on two USB2.0 buses simultaneously.

By triggering only on the most important signal events, Visual Trigger can

save hours of capturing and manually searching through acquisitions. In

seconds or minutes, you can find the critical events and complete your

debug and analysis efforts. Using the Mark All Trigger Events feature, once

your Visual Trigger is set, your oscilloscope can automatically search the

entire acquired waveform for all events with the same characteristics and

mark them for you - a great time-saving feature.

DDR memory bus events involve clocks, strobes and data channels as well

as multiple amplitudes and bursts of data.

DDR memory. Visual Trigger used to isolate a rare occurrence of a write burst on a

specific bit pattern in DDR3. The trigger event is a Write DQ burst of 11000000, when the

DQ launch starts from a non-tri-state voltage value. DDR memory bus events involve

clocks, strobes and data channels as well as multiple amplitudes and bursts of data.

Boolean logic trigger qualification. Boolean logic using logical OR allows the user to

simultaneously monitor each bit and capture the occurrence of an anomaly at any point

in the acquisition.
