Digital phosphor technology

The DPO7000C Series' digital phosphor technology provides you with fast

insight into the real operation of your device. Its fast waveform capture rate

– greater than 250,000 wfm/s – gives you a high probability of quickly

seeing the infrequent problems common in digital systems: runt pulses,

glitches, timing issues, and more.

Digital phosphor technology enables greater than 250,000 wfm/s waveform capture rate

and real-time color grading on the DPO7000C Series.

Waveforms are superimposed with one another and waveform points are

color coded by frequency of occurrence. This quickly highlights the events

that occur more often over time or, in the case of infrequent anomalies,

occur less often.

With the DPO7000C Series, you can choose infinite persistence or variable

persistence, determining how long the previous waveform acquisitions stay

on-screen. This allows you to determine how often an anomaly is occurring.

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.
