RF testing

Choosing the right antenna can make or break your compliance testing results. This practical guide walks engineers through the essentials—frequency range, polarization, gain, and directivity—while decoding which antenna types deliver the most accurate, reliable measurements in real‑world EMC and RF test environments.

Discover how PCB layout choices can dramatically alter S‑parameter measurements of high‑speed ESD protection devices—especially in the femtofarad range. Through 3D EM simulations and real‑world testing, this article reveals why accurate modeling and optimized test boards are essential for reliable high‑speed performance.

Siglent Technologies has introduced the SHN900A series handheld vector network analyzer with a frequency range as high as 26.5GHz.
