Keysight U9391F Comb Generator
The Keysight U9391F Comb Generator is engineered for precision phase calibration, adhering to the National Institute of Standards and Technology (NIST) standard, specifically for nonlinear measurements with the PNA-X nonlinear vector network analyzer (NVNA). This advanced comb generator utilizes InP MMIC technology, ensuring exceptional phase stability for optimal performance as a phase reference.
Featuring Keysight’s patented design, the U9391F incorporates a USB-controlled frequency divider that accommodates a broad range of input signal frequencies from 10 MHz to 50 GHz, alongside a small minimum tone spacing of just 10 MHz. This innovative generator exhibits lower sensitivity to input power and fundamental frequency variations, enabling users to calibrate the device at a singular input power level and frequency before applying that calibration across diverse conditions.
To ensure peak performance, the U9391-60009 sine to square wave converter is included as a standard accessory, facilitating optimal output for frequencies exceeding 26.5 GHz with a sine wave input of less than 100 MHz.
