Oscilloscope Experience Redefined:
If you can’t see the problem, it is hard to troubleshoot
it. With an industry-leading one million waveforms
per second update rate, the InfiniiVision 4000 X-Series
gives you the highest probability of capturing random
and infrequent events that you would miss on an
oscilloscope with a lower waveform update rate.
Powered by MegaZoom IV smart memory technology,
the InfiniiVision 4000 X-Series not only lets you see
more waveforms, but it has the uncompromised ability
to find the most difficult problems in your design. Unlike
other oscilloscopes, uncompromised ability means:
• Always-fast, responsive operation
• No slowdown with logic channels on
• No slowdown with protocol decoding on
• No slowdown with math functions turned on
• No slowdown with measurements turned on
As oscilloscopes acquire data, process it, and plot it to the screen, there is inevitable “dead time,” or the time oscilloscopes
miss signals completely. In general, the faster the waveform update rate, the shorter the dead time. The shorter the dead
time, the more likely an oscilloscope is to capture anomalies and infrequent events. This is why it is critical to select an
oscilloscope with a fast waveform update rate.
What is waveform update rate and why is it important?
Figure 3: The 4000 X-Series captures a glitch occurring once in
a million waveform cycles.

capturing infrequent events.

of capturing infrequent events.
