Kerry Wong Unveils Active Probe to Outperform Passive Counterparts
Kerry Wong has showcased a pre-release active probe that aims to surpass the limitations of standard passive probes. The new probe, developed by Prignitz Mikrosystemtechnik GmbH, is set to debut at a lower price than competitive probes.
Active probes, unlike their passive counterparts, do not rely on input capacitance, which can interfere with high-frequency signals. This makes them ideal for precision measurements. Wong's demonstration highlights the advantages of active probes over passive ones, which include reduced noise and interference.
The active probe comes with a tripod for stability during use. However, it's important to note that building your own active probe can be cost-effective, but most DIY versions may not reach frequencies as high as 3 GHz. To test the probe, square waves were used as the test waveform due to their odd-numbered harmonics rising above the target frequency. While the probe adapters may cause some ringing on the input signal, the overall setup shows significant value compared to a standard passive probe.
Kerry Wong's pre-release active probe, developed by Prignitz Mikrosystemtechnik GmbH, offers a promising alternative to passive probes. It addresses issues such as input capacitance interference and noise, and it's set to debut at a competitive price. Despite some minor ringing on the input signal, the active probe setup shows significant value and is expected to make a notable impact in the market.
