Product Overview

KEYSIGHT U9391F

The Keysight U9391F Comb Generator was developed to provide precision phase calibration, referenced to the National Institute of Standards and Technology (NIST) standard, for nonlinear measurements using the PNA-X nonlinear vector network analyzer (NVNA). Comb generators generate frequency harmonics from an input RF signal. The U9391F comb generator uses InP MMIC technology which ensures superior phase stability of the comb enabling it to be used as a phase reference.

Keysight’s patented comb generator offers a customer selectable USB controlled frequency divider which allows for broad range of input signal frequencies from 10 MHz to 50 GHz and small minimum tone spacing of 10 MHz. The input power and fundamental frequency have lower sensitivity than other comb generators. So you can calibrate the comb generator at a single input power level and frequency and then successfully apply the calibration across a wide range of input powers and fundamental frequencies.

The U9391-60009 sine to square wave converter is needed as the comb generator will not function at its optimum level for output frequencies above 26.5 GHz, with a sine wave input of less than 100 MHz. The U9391-60009 is included as a standard accessory for the U9391F and the U9391G.
