In addition, with a standard offset range capability from 0.01 Hz to 100 MHz, the E5500 B-series provides the capability, flexibility, and versatility to meet changing and demanding needs placed upon the R&D engineer. By building upon 30 years of Agilent low phase noise, RF design and measurement experience, the E5500 series solutions continue to provide excellent measurement integrity, repeatability, and accuracy. The E5500 phase noise measurement solutions use the power of a flexible software program to automate phase noise carrier measurements. The E5500 A-series solutions include the 70420A phase noise test set, which contains phase detectors and phase-lock loop circuitry, a high speed VXI digitizer with mainframe and high speed VXI-to-PC interface for base-band signal analysis, selected low-noise frequency downconverters, and measurement software. When combined with a PC running Windows NT 4.0, this series provides fast phase noise measurements of carrier frequencies from 50 kHz to 1.6 GHz, 6.0 GHz, 18 GHz, or 26.5 GHz over offset-from-carrier frequencies of 0.01 Hz to 4 MHz.1 The E5500 B-series includes the 70420A phase noise test set, a Pentium PC running WindowsNT 4.0, a PC digitizer, and an RF spectrum analyzer, selected low-noise frequency downconverters, and measurement software. This series of solutions provides phase noise measurements of carrier frequencies from 50 kHz to 1.6 GHz, 6.0 GHz, 18 GHz, or 26.5 GHz over offset-from-carrier frequencies from 0.01 Hz to 100 MHz. A variety of signal generators— such as the 8662A, 8663A, 8643A, 8644B, 8664A/B, 8665A—can also be added to provide a low-noise reference signal. Phase Noise Measurement Software A graphical user interface provides measurement menus allowing the operator to specify the measurement process, including the calibration of the system. Several output formats are available to the user, including plots of the single-sideband phase noise power of the signal, integrated noise power, or the calculated Allan variance. A real-time measure-ment mode is available to monitor the level of phase noise and discrete spurs as changes are made to the device-under-test. The E5500 series phase noise measurement software requires a Pentium PC with 32 MBytes of RAM, a 1 GByte hard drive, and Windows NT 4.0. 1 It can be extended to cover offset ranges up to 100 MHZ.
