The Fluke Calibration 9640A and 9640A-LPNX RF Reference Sources are designed specifically for RF calibration, featuring a calibration oriented user interface, precision signal level and attenuation, high signal purity and precision low distortion modulation. This unique combination of features and performance makes them clearly superior to the general purpose signal generators and an array of ancillary equipment often used in traditional RF calibration systems. The 9604A-LPNX low phase noise version provides superior phase noise performance.
