The Agilent E4422A is an analog RF signal generator covering 250 kHz to 4000 MHz, identified on its specifications as the ESG-4000A. It produces continuous-wave and modulated RF signals across this span with 0.01 Hz frequency resolution, an output level window of +13 dBm down to -136 dBm, and a 50 ohm output impedance.
An analog signal generator supplies a known, controllable RF stimulus — a defined frequency, amplitude, and modulation — that an engineer applies to a device under test to characterize its response. The E4422A pairs this carrier-sourcing role with built-in amplitude, frequency, phase, and pulse modulation, so a single instrument can both generate the carrier and impress test modulation onto it.
ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, which lets us manage availability and fulfillment directly. Every used unit is inspected and functionally verified by our in-house team before it ships, while new units ship factory-sealed exactly as received from the manufacturer.
The instrument carries Agilent Technologies branding. Agilent was spun off from Hewlett-Packard in 1999, and its electronic test-and-measurement business was subsequently established as Keysight Technologies in 2014.
