Digital Phosphor Oscilloscopes / Digital Serial Analyzers / Mixed Signal Oscilloscopes
Debugging
Throughout the design cycle, DPO/DSA70000B and MSO70000 Series
oscilloscopes provide the ability to debug malfunctioning subsystems and
isolate the cause. Using FastAcq’s high waveform capture rate, you can
quickly identify signal anomalies that occur intermittently – saving minutes,
hours, or even days by quickly revealing the nature of faults so sophisticated
trigger modes can be applied to isolate them. Using Pinpoint triggers,
infrequent events such as glitches or signal runts caused by bus contention
or signal integrity issues can be captured, analyzed and then eliminated.
FastAcq – Expedites Debugging by Clearly Showing
Imperfections
More than just color-grading or event scanning, FastAcq’s proprietary
DPX
® acquisition technology captures signals at more than 300,000
waveforms per second on all four channels simultaneously, dramatically
increasing the probability of discovering infrequent fault events. And with a
simple turn of the intensity knob you can clearly “see a world others don’t
see”, displaying the complete picture of your circuit’s operation. Some
oscilloscope vendors claim high waveform capture rates for short bursts of
time, but only DPO/DSA70000B and MSO70000 oscilloscopes, enabled
by DPX technology, can deliver these fast waveform capture rates on a
sustained basis.
Pinpoint ® Trigger
Whether you’re trying to find a problem signal or need to isolate a section
of a complex signal for further analysis, like a DDR read or write burst,
Tektronix’ Pinpoint triggering provides the solution. The Pinpoint trigger
system uses Silicon Germanium (SiGe) technology to provide very high
trigger sensitivity with very low trigger jitter and the ability to capture very
narrow glitches. Pinpoint triggering allows selection of virtually all trigger
types on both A and B trigger events delivering the full suite of advanced
trigger types for finding sequential trigger events. Pinpoint triggers provide
trigger reset capabilities that begin the trigger sequence again after a
specified time, state, or transition so that even events in the most complex
signals can be captured. Other oscilloscopes typically offer less than 20
trigger combinations; Pinpoint triggering offers over 1400 combinations,
all at full performance.
With Enhanced Triggering, trigger jitter is reduced to <100 fs. With this
stability at the trigger point, the trigger point can be used as a measurement
reference.
Integrated Logic Channels – Provide time-correlated analog and digital visibility for system
debugging.
Logic Pattern Triggering
Logic pattern triggering allows logic qualification that controls when to
look for the faults and ignore events that do not occur during the desired
state. On the MSO70000 Series, up to 20 bit wide logic pattern triggering
enhances the Pinpoint trigger capabilities by helping you isolate the specific
system state and analog events that are causing system failure.
Integrated Logic Channels (MSO70000 only)
The MSO70000 extends the debug capabilities of a 4-channel oscilloscope
with an additional 16 logic channels that can be used to provide system
level context when the fault occurs. This context, such as an illegal system
state or error, may be the clue that leads to the root cause. When other
oscilloscopes require you to use a logic analyzer to see the digital data you
need to solve your debugging challenge, the MSO70000 can effectively
debug and verify many digital timing issues in the system more quickly and
easily. With 80 ps timing resolution and channel-to-channel skews of as little
as 160 ps, the integrated logic channels allow you to view and measure
time-correlated digital and analog data in the same display window.
iCapture (MSO70000 only)
When an anomaly is seen on digital lines, iCapture delivers new insight
into the analog behavior of the digital signals. With iCapture, you can
route any 4 of the 16 logic channels to the MSO70000’s analog acquisition
system so that these signals can be viewed in finer detail. iCapture’s unique
multiplexer circuitry provides simultaneous digital and analog views of
signals without having to move the logic probe or double probe the circuit.
