New communication technologies such as 3rd Generation Mobile (IMT 2000), microwave digital broadcast, high-speed multimedia mobile access (MMAC), and satellite-based services require the latest in spectrum and modulation measurement capabilities. Furthermore, these new services must be introduced in less time and for more users than ever before. The R3267 is a high-performance spectrum analyzer designed to meet these needs. The R3267 features a frequency span accuracy within +/- 1% and a dynamic range of -154 dBc/Hz (typ.) in the 2 GHz band to allow accurate, repeatable measurements for high-quality digital signals. Further, its 10 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 signals. Finally, with a frequency range from 100 Hz to 8 GHz, the R3267 allow comprehensive measurements of even high frequency systems.
