Wireless technology has become a vital asset for military and defense. To ensure successful design, deployment, and operation of systems utilizing 5G, advanced test processes are paramount to precise implementation, optimization, and maintenance. This paper explores a number of use cases and examines verification processes, as well as some comprehensive test solutions.
This resource touches base on a challenging but important aspect of radiated emissions measurements on an OATS, SAC, or FAR. A compliant test site produces repeatable test results and instills confidence in both customers and test personnel.
Design, Verification, Troubleshooting and Maintenance of secondary surveillance radar (e.g. IFF-based radar) has never been more demanding. Proper design and operation of SSR systems can mean the difference between life and death. To reduce the possibility of a catastrophic event, federal aviation safety standards require transponders to undergo periodic maintenance and calibration.
Wireless InSite supports the simulation of RF interactions with engineered electromagnetic surfaces (EES). This allows modeling of passive metasurfaces designed to optimize wireless communication coverage by manipulating how signals propagate through a scene. This paper demonstrates how Wireless InSite simulates and analyzes the channel characteristics of EES in any environment, including indoor, outdoor, outdoor to indoor, and others.
Dielectric Resonator Oscillators (DROs) are compact, narrowband devices that stabilize frequency with a dielectric resonator, enabling the generation of microwave signals with extremely low phase noise. Because of these advantages, DROs are prime choices for advanced, high-frequency applications, such as integration into radar and communications systems.
The RFPD-RT-2444-1 mmWave converter is a standalone solution for use in the 24 to 44 GHz range and is branded “RadioThorium.” The 24-44 GHz RadioThorium block up- and down-converter was developed by Signal Craft Technologies (Calgary, Canada) in partnership with Richardson RFPD and Analog Devices. The module is designed to interface directly with an external baseband platform, such as Analog Devices’ MxFE (Mixed- Signal Front-End) or similar SDR IC. Up to x4 modules can be combined in parallel to create complex MIMO applications.
Conformance tests are performed on serial data interfaces such as USB, HDMI and PCI Express to ensure interoperability between electronic devices and accessories. In cases where signal integrity problems are encountered, the R&S®RTP oscilloscope supports root cause analysis by providing powerful tools such as eye diagrams, jitter and noise separation as well as time domain reflectometry.
The constantly growing demand for devices with wireless communication ports is pushing devices to operate at increased bandwidths over a wide frequency range. It is becoming increasingly important to ensure every design engineer has an all-purpose radio frequency (RF) amplifier at hand.

This paper provides an introduction to error vector magnitude (EVM), which is the primary metric of modulation accuracy. It discusses the fundamentals of the digital modulation schemes used in modern radio frequency communications systems, in particular, APSK and QAM, the fundamentals of error vector magnitude, and basics of constellation diagrams and how constellation diagrams can often be used to diagnose or troubleshoot the common root causes of EVM.
