Agilent/ HP E4428C ESG Analog Signal Generator, 250 kHz to 6 GHz

The E4428C ESG analog signal generator delivers outstanding spectral purity, level accuracy, output power, and analog modulation performance up to 3 or 6 GHz for all general-purpose test needs. This makes the E4428C ESG a superb choice for general-purpose tests requiring CW, AM, ØM, and FM receiver and component test signals in the cellular, ISM, and UNII frequency bands.

Single-Sideband (SSB) phase noise is an extremely important specification of a signal generator. For example, if used for measuring the adjacent channel selectivity of a receiver, your test results might indicate a failure when your receiver is actually functioning properly if the phase noise of the signal generator is too high. With a typical SSB phase noise performance of -134 dBc/Hz at 20 kHz offset from a 1 GHz carrier, the E4428C ESG will meet your demanding performance needs. Other key applications that require high spectral purity include LO substitution, low-jitter clock stimulus, blocking/interference signals, and in-channel measurements close to the carrier.
