Agilent/Keysight U9361G

The Keysight U9361G RCal Receiver Calibrator is a compact, USB-powered device that corrects systematic errors in RF and microwave signal paths, enabling precise measurements across the frequency spectrum. It transfers absolute power accuracy and applies magnitude and phase corrections to move the measurement reference plane to the device under test output, improving receiver test system accuracy by an order of magnitude.
