Persistence mode is an oscilloscope feature that lets you view the history of your signal at the same time as the live waveform. This means that intermittent glitches, jitter and noise remain on the display for longer, giving you a chance to catch and analyse them. You can use persistence mode to search for a problem without knowing exactly what sort of error you are looking for. Once you see an out-of-specification waveform on the screen, you can then switch to a standard display mode and set up the scope’s advanced triggers to capture the problem in more detail.
Pico’s persistence mode shows you multiple waveforms on every screen update, making the display more responsive. There is a digital colour mode that shows stable data in “hot” colours and intermittent data in “cool” colours. And, with a stable trigger signal, this mode can even display eye patterns for analysing serial data waveforms. Digital colour mode is complemented by an analogue persistence mode, which emulates an analogue oscilloscope by drawing new data at full intensity while allowing old data to fade away. This mode uses a single colour per channel.
To use the new feature, you just click the “Persistence Mode” button and let PicoScope do the rest. The program lets you customise the display colours and persistence parameters if you need to.
Alan Tong, Managing Director of Pico Technology, commented: “The new persistence mode is ideal for research and development, field servicing and troubleshooting. Like all our software updates, it’s free of charge to all our customers.”
