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.

Figure 9. Mask testing evaluated > 22 M waveforms in just 2 minutes.

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.

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 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.
