Detecting Glitches Using Mask Limit Testing
- 11 Dec 2020
With mask limit testing PicoScope will highlight any parts of a waveform that fall outside the mask area. The highlighted details persist on the display, allowing the scope to catch intermittent glitches while you work on something else. The measurements window counts the number of failures, and can display other measurements and statistics at the same time.
Numerical and/or graphical mask editors can be used to enter accurate mask specifications, modify existing masks, and import and export masks as files.
In addition to testing waveforms in the oscilloscope, mask limit testing can also be applied to the spectrum analyzer, allowing you automate finding problems in both the time and frequency domains.
Waveform mask limit test - Fail
Frequency domain mask limit test - Pass

PicoScope
Pico is the market leader in PC Oscilloscopes — the modern alternative to the traditional benchtop oscilloscope.
High-end features such as serial decoding and mask limit testing are included as standard — no more expensive "options" to pay for. Pico also have a long history of adding new features through free software upgrades — your PicoScope keeps getting better.
