英文技術說明

Excellent all-inclusive RF and analog modulation performance up to 3 or 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, ΦM, and FM receiver and component test signals in the cellular, ISM, and UNII frequency bands.Lowest Single-Sideband (SSB) phase noise performance in its price classSingle-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.
