Tech Brief Provides Insight on Creating Wireless Handover Tests and Fading Simulations with Low-cost Programmable Devices

Handover testing is a crucial stage in the development and deployment of wireless systems in which the cellular devices are in motion. A handover is most simply envisioned as a person driving down an interstate highway while on a cellular call and the call being long enough in duration to necessitate that it is handed over to the next cell tower in proximity to the car as the call begins to fade away from its originating tower.

How to set up radar testing with FMCW and chirp capability using low-cost programmable RF signal generators

FMCW and chirp (pulsed linear frequency modulated) radar are some of the most common radars used globally. These types of radar are designed for electronic warfare (EW) and defense, as well as a variety of commercial aerospace applications. In the case of defense, FMCW and chirp signals are commonly used in terrain-following radar for under-the-radar flying, surveillance, and for targeting systems.

Putting the Less in Wireless Testing

“Wireless testing” is defined as the actions necessary to assess a device's capability to first, properly and securely connect with other devices and networks, and second, complete the desired operational tasks expected of the connected device successfully.
