Mask/limit testing (option)
Whether you are performing pass/fail tests to specified
standards in manufacturing or testing for infrequent signal
anomalies, mask/limit testing can be a valuable productivity tool
(DSOX4MASK). The 4000 X-Series features powerful hardware-
based mask testing and can perform up to 270,000 tests per
second. You can select multiple test criteria, including the ability
to run tests for a specific number of acquisitions, a specified time,
or until detection of a failure.

Search and navigation
The parametric and serial bus search and navigation feature
comes standard on the 4000 X-Series oscilloscopes. When you
are capturing long, complex waveforms using an oscilloscope’s
deep acquisition memory, manually scrolling through stored
waveform data to find specific events of interest can be slow and
cumbersome. With automatic search and navigation capability,
you can easily set up specific search criteria and then quickly
navigate to “found and marked” events. Available search criteria
include edges, pulse width (time-qualified), rise/fall times
(time-qualified), runt pulses (time-and level-qualified), frequency
peaks (FFT function, threshold and excursion qualified), and serial
bus frames, packets, and errors.
Figure 10a. The 4000 X-Series was set up to capture data signals with
various rise time edges. Using the search and navigation capability, the
oscilloscope was able to find, mark (white triangles), and quickly navigate
to 16 occurrences of “out of compliance” rise-time edges.
Figure 11. Using the error condition search, the 4000 X-Series quickly
found 5 places with a missing acknowledgment in an I²C serial bus. The
navigation feature moves between the errors and zooms automatically to
show the error packet.
Figure 10b. The 4000 X-Series was set up to capture clock signals for
FFT analysis. Using the search and navigation capability, the scope
found, marked (white triangles) and quickly navigated to the first 11
frequency peaks occurrences. You can sort it in the order of frequency or
amplitude.
