The Advantest R3273 are high-performance spectrum analyzers designed to meet these needs. The R3273 features a frequency span accuracy +/-0.2(typ.) and a dynamic range of -145 dBc/Hz (typ.) in the 2 GHz band to allow accurate, repeatable measurements for high-quality digital signals. Its 1 Hz to 10 MHz resolution band with filter and ability to perform a 70 dB (typ., at 5 MHz offset) ACP measurement on W-CDMA makes it ideal for testing of wide band sig-nals. With a frequency range from 26.5 GHz, theR3273 allow comprehensive measure-ments of even high frequency systems. The digital modulation analysis option offers one-button testing of modulation parameters for communication systems including PHS, PDC, IS-136, DECT, GSM, GPRS, EDGE, IS-95, cdma2000, Bluetooth as well as W-CDMA (3GPP). The R3273 provides excellent value with its combination of spectrum and optional modulation analyzer, so that it can be used with applications ranging from research and development of communication devices and modules, to pro-duction line and deployment testing of communication infrastructure equipment. The R3273: a new family of analyzers to test today’s, and tomorrow’s communication systems.
