Channel Environment Replicator (CER) applications simulate and recreate outdoor environments in which radar systems must operate. It’s a much less expensive testing method when compared to the potential complications encountered in more traditional field testing, though testing a moving target in such an application isn’t all that simple.
The concept of load-pull simulation is where a load or source impedance is swept by an active device and its performance is measured. Recently, advancements have been made to data file formats by load-pull measurement system vendors to expand the usefulness of load-pull characterization. These new file formats support a sweep of an independent variable such as input power, DC bias, temperature, or tone spacing, in addition to the swept source or load impedance. The NI AWR Design Environment™ software enables designers to import and manipulate these load pull data sets in a circuit simulator which greatly simplifies and speeds the design process, and gives them a broader design space to explore. This white paper covers in-depth information on how to use enhanced load-pull measurements for base station power amplifier designs.
Immission measurement studies on the exposure of the general public to high frequency electromagnetic fields (HF EMF) have been limited to inspecting individual wireless services and the wireless Internet. As a solution, Narda offers the SRM-3006 as a suitable instrument for these measurements.
