The Fluke 5820A is a precision oscilloscope calibrator engineered to verify and calibrate oscilloscopes up to 2.1 GHz bandwidth. This portable instrument generates leveled sine waves, fast edges, time markers, and amplitude signals for validating both analog and digital oscilloscope performance in laboratory and on-site environments.
