The S94521A arbitrary load control X-parameters (ALC) provides passive, active or hybrid load control for extracting X-parameter models far from 50 Ohms. This application is ideal for high power transistor/amplifier design and validation.

The new ALC application is highly integrated and interactive with the NVNA software providing setup, dc I/V selection, measurement, analysis, and model extraction. Each tab in the application guides you through the process. Adjustments can be made, based on measurement results, before selecting to extract the final X-parameter model. Built-in flexibility enables integration into user systems ranging from the very simple to very complex.
