Agilent Technologies is now offering a free application program that helps to make accurate and repeatable phase-lock-loop (PLL) measurements (and jitter-transfer testing) using a precision jitter source and a measurement receiver. The Agilent 86100CU-400 PLL and jitter spectrum measurement software runs on an external personal computer (PC) or the Agilent 86100C DCA-J oscilloscope with MS Excel installed. Ideal for use with that oscilloscope, the Microsoft® Excel-based software helps provide details on the causes of jitter and phase noise on data and clock signals in high-speed communications systems sources. The software includes preconfigured setups and automated report generation to verify adherence to the PCIe 1.1 and 2.0 PLL compliance test guidelines, SONET/SDH jitter transfer tests, PCI Express reference clock measurements, and spread-spectrum clocking (SSC) modulation analysis. Free copies of the software are available starting in September by visiting the company's website for more details.
