Oversampling, Virtual Probes, and Multi-probe Spherical Near-field Measurement Systems

Oversampling, Virtual Probes, and Multi-probe Spherical Near-field Measurement Systems

Do you know what virtual probes are? Why and where they are useful in antenna measurement? Learn about oversampling and virtual probes, and their effective role in spherical near-field antenna measurements with multi-probe technology from our latest quick-read article you’ll find in the new Fast-Scan Learning resource section of our website.

It’s a quick review of the application of the Nyquist criterion in antenna measurements, how a technique called oversampling adds virtual probes to complete near-field antenna measurements for accurate near-field to far-field transformation, and what technology requiring testing can benefit from the technique.
