Keysight Agilent HP E4421A

E4421A Agilent RF Generator

250 kHz to 3000 MHz Signal Generator

The E4421A is a 3 GHz RF Generator from Agilent. An rf generator is a tool engineers use to generate sinusoidal outputs while testing electronic equipment. The output will automatically have its frequency varied or swept between frequencies. A “sweep” is one complete cycle of a frequency variation. Engineers use rf signal generators as test equipment, mostly to measure responses of filters, amplifiers, and electrical components.
