Affordable Active Probe Promises High-Frequency Signal Testing
Electronics enthusiasts are abuzz with the news of a new active probe, set to debut at a competitive price. The device, showcased by Kerry Wong, promises to address common issues with passive probes, offering stability and value.
Active probes, unlike their passive counterparts, circumvent problems related to input capacitance and noise. This makes them ideal for testing high-frequency signals. However, building your own active probe can be challenging, with most DIY versions struggling to reach frequencies above 3 GHz.
Square waves are often employed as test waveforms due to their odd-numbered harmonics, which can help identify and analyze these high-frequency issues. Wong's active probe, set to launch at a lower price than competitors, aims to provide a practical solution for hobbyists and professionals alike. Despite some ringing caused by probe adapters, the active probe setup shows significant promise.
Kerry Wong's active probe, set to debut at an affordable price, offers a promising solution for high-frequency signal testing. By bypassing issues with passive probes and providing stability with a tripod, this new tool could become a valuable addition to many electronics enthusiasts' toolkits.
