Mask limit testing

Mask limit testing allows you to compare live signals against known good signals, and is designed for production and debugging environments. Simply capture a known good signal, draw a mask around it, and then attach the system under test. PicoScope will perform pass/fail testing, capture intermittent glitches, and can show a failure count and other statistics in the Measurements window.

Mask limit testing is available for both the oscilloscope and spectrum analyzer, allowing you automate finding problems in both the time and frequency domains.

The numerical and graphical mask editors can be used separately or in combination, allowing you to enter accurate mask specifications, modify existing masks, and import and export masks as files.

In addition to testing waveforms in the time domain mask limit testing can be applied to frequency domain signals.
