Mixed Signal Oscilloscopes — MSO4000B, DPO4000B Series
Digital phosphor technology
Mixed signal design and analysis (MSO
series)
Digital phosphor technology provides you with fast insight into the real
operation of your device. Its fast waveform capture rate – greater than
50,000 wfm/s – gives you a high probability of quickly seeing the infrequent
problems common in digital systems: runt pulses, glitches, timing issues,
and more.
The MSO models provide 16 digital channels which are tightly integrated
into the oscilloscope's user interface. This simplifies operation and makes it
possible to solve mixed-signal issues easily.
Waveforms are superimposed with one another and waveform points that
occur more frequently are intensified. This quickly highlights the events that
over time occur more often or, in the case of infrequent anomalies, occur
less often.
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.
The MSO Series provides 16 integrated digital channels enabling you to view and
analyze time-correlated analog and digital signals.
Color-coded digital waveform display
This oscilloscope has redefined the way you view digital waveforms. One
common problem shared by both logic analyzers and mixed-signal
oscilloscopes is determining if data is a one or a zero when zoomed in far
enough that the digital trace stays flat all the way across the display. Color-
coded digital traces display ones in green and zeros in blue.
Digital phosphor technology enables greater than 50,000 wfms/s waveform capture rate
and real-time intensity grading.
The multiple transition detection hardware shows you a white edge on the
display when the system detects multiple transitions. White edges indicate
that more information is available by zooming in or acquiring at faster
sampling rates. In most cases zooming in will reveal the pulse that was not
viewable with the previous settings. If the white edge is still present after
zooming in as far as possible, this indicates that increasing the sample rate
on the next acquisition will reveal higher frequency information than the
previous settings could acquire.
Accurate high-speed probing
The TPP Series probes, included standard with every MSO/DPO4000B
Series oscilloscope, provide up to 1 GHz of analog bandwidth, and less
than 4 pF of capacitive loading. The extremely low capacitive loading
minimizes adverse affects on your circuits and is more forgiving of longer
ground leads. And, since the probe bandwidth matches or exceeds your
oscilloscope bandwidth, you can see the high-frequency components in
your signal which is critical for high-speed applications. The TPP Series
passive voltage probes offer all the benefits of general-purpose probes like
high dynamic range, flexible connection options, and robust mechanical
design, while providing the performance of active probes. In addition, a low-
attenuation, 2X version of the TPP probes is available for measuring low
voltages. Unlike other low-attenuation passive probes, the TPP0502 has
high bandwidth (500 MHz) as well as low capacitive loading (12.7 pF).
