VNA-VSB

VNA Sandbox is a circuit board with many different experiments to demonstrate the features of VNAs in general and the VNA0440e in particular. It comes with a printed tutorial showing how to measure and explaining the results you see. It can also be used as a reference to verify the correct operation of a test setup. The VNA Sandbox is based on UFL connectors that are also used to measure consumer miniature RF circuits like mobile phones, Wi-Fi access points etc. it contains a dual calibration kit for quick calibration, which is supported by the VNA0440e software. This reduces a full 2-port calibration from 12 steps to only 4 steps. The lights on the front panel of the VNA0440e will guide through the calibration process. The board contains several 1-port impedances, 2-port passive circuits like attenuators and filters, two antennas and several active circuits that are measured using the bias generator.
