Radio Frequency (RF) Testing

Radio signal frequencies are rising to the millimeter-wave (mmWave) range as applications such as 5G networks and automotive radar systems seek more bandwidth at higher frequencies. Testing is an important part of producing new products at mmWave frequencies and coaxial cable assemblies are vital parts in getting signals from a signal generator to a device under test (DUT) and then to an analyzer.

This article addresses China’s latest requirements, including technical details, for 2.4 GHz and 5 GHz equipment.

RF field probes are specialized measuring instruments with unique specifications and performance characteristics. This article details the main factors to consider in selecting a probe appropriate to your testing needs.

In this first part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in North America for radio modules and equipment which contain radio modules.

Many real-time spectrum analyzer solution providers provide in-one-instrument add-ons which allow users to perform both the traditional swept-mode measurements in addition to real-time measurements.

This article will summarize the major changes of the new revision of ISO/IEC 17025-2005, present the new outline of the standard and will discuss the new concept of a “risk-based” approach of implementing requirements.

Electromagnetic compatibility of wireless communications and sensor networks with mission critical electronic equipment is assessed for below-deck spaces on ships and submarines. With intentional wireless emission of radio-frequency (RF) energy into the reverberant spaces, it is necessary to measure and characterize the statistical electromagnetic environment (EME) and to predict maximum electric field strengths to a specified confidence level.
