Agilent MegaZoom III - FASTEST waveform update rates

MegaZoom III - FASTEST waveform update rates, without compromise
With Agilent's MegaZoom III technology, the 6000 Series oscilloscopes provide the fastest waveform update rates in the industry, without compromise. These scopes can produce up to 100,000 real-time waveforms per second, without the need to select special acquisition modes that may entail tradeoffs in oscilloscope performance and functionality.

Update rates in this range can be extremely important when you are trying to capture very infrequent events and signal anomalies such as dynamic jitter and random glitches. The image on this page shows an example of a high-speed signal that includes jitter (near left side of screen), vertical noise (top and bottom of waveform), and a very infrequent glitch (near center of screen). With fast waveform update rates, we can clearly see the dynamic nature of the jitter, which appears to be dominated by deterministic jitter (DJ). However, the biggest benefit of fast waveform update rates is this scope’s ability to easily capture the very infrequent glitch, which is actually a metastable state. This particular glitch only occurs approximately 1 time every 50,000 cycles of the input data signal that we are observing. With 100,000 real-time waveforms per second, we are able to see this glitch displayed on the scope’s screen multiple times a second.

If you were using another scope in this class that has a maximum update rates of just 3500 waveforms per second, you would have to maintain probe contact with the test point for more than 14 seconds (on average) in order to capture just one glitch. But if you were using the typical debugging method of moving your probe from test point to test point every few seconds, you would probably miss capturing this glitch using a scope with slower update rates.
