Additional Features: Frequency Range: 100 Hz-26.5 GHz  Dynamic Range: +30 dBm - -125 dBm  Input Impedance: 50 ohms  Residual FM: <3 Hz x Np - p/.1sec  Resolution Bandwidth: 10 Hz - 10 MHz  Video Bandwidth: 1 Hz - 10 MHz  The R3273 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 26.5 GHz, the R3273 allow comprehensive measurements of even high frequency systems. In addition, the optional digital modulation analysis option offers one-button testing of modulation parameters for communication systems including PHS, PDC, IS-136, DECT, GSM, and IS-95 as well as W-CDMA and CDMA-2000. 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, modules, to production line and deployment testing of communication infrastructure equipment.
