such as switching from an oscilloscope to a spectrum analyser with a couple of clicks or running both instruments in parallel. Additionally, PicoScope 7 software benefits from regular free-of-charge software updates that eliminate the need for hardware replacements and ensure compatibility with future technologies. Recent examples include addition of new serial protocol decoders such as I3C and CAN XL, on top of the 30+ decoders already included. Features such as mask limit testing allows the comparison, in time- or frequency-do- mains, of live signals against known good signals. Results can be stored and displayed in up to 10,000 waveform buffers, showing all waveforms or just those that violate the mask, which is ideal for finding intermittent faults. Failure counts can be recorded to help with statistical analysis of a design performance. Actions are things that PicoScope can be programmed to do when certain events occur, including mask failures. Actions include ‘Stop the capture’, ‘Save waveform to disk’, ‘Play a sound’, ‘Trigger the signal generator’, and ‘Run an external application’. Taken together, these tools enable engineers to perform extended testing and deep analysis of a circuit before signing it off as ‘good to go’.

PicoScope facilitates collaboration among engineers, even across different geographical locations. As well as local control of a PicoScope, remote users can access and control instruments, share data, and collaborate on projects using third party client-server networking. This feature is particularly valuable for distributed teams and remote work scenarios, enabling seamless cooperation and knowledge sharing. Conclusion PC-based instruments are rapidly transforming the landscape of electronic system debugging and validation. By leveraging the computational power, flexibility, and scalability of personal computers, engineers can overcome the limitations of traditional benchtop oscilloscopes. With cost and space efficiency, integration and automation capabilities, and the ability to collaborate remotely, PC-based instruments provide a new level of flexibility, productivity, and adaptability. As technology continues to advance, the adoption of PC-based instruments is expected to grow, driving innovation, and further enhancing the efficiency of electronic system design and testing processes.

The integration of PicoScope with software development tools and automation systems is a game-changer for engineers. Operating in the same Windows, Linux, or Mac platforms that designers have used to create their systems, PicoScope engineers can quickly execute complex measurement sequences, perform data analysis in real-time, and integrate the results into their overall design flow. This integration streamlines the debugging and validation process, improves efficiency, and enhances productivity.
