Product Overview

RENT KEYSIGHT / AGILENT U9391C Comb Generator (Call for Availability)

The Keysight Technologies U9391C comb generators were developed to provide precision phase calibration, for non-linear measurements using the PNA-X nonlinear vector network analyser (NVNA), referenced to the National Institute of Standards and Technology (NIST) standard. Additionally, the comb generators can be used to calibrate PNA and PNA-X network analyzers for phase and delay measurements of frequency converters without requiring reference or calibration mixers. 

A built-in frequency divider, selectable via the PNA-X, reduces the noise of the Keysight U9391C comb generator. You can set drive frequency at 1, 2 , 4, 8 or 16 times the pulse repetition frequency (PRF). Combining a frequency divider with a wide input signal frequency range allows for a broad range of possible harmonics spacing, making this suitable for characterizing non-linear devices. This module has a trigger output which enables synchronization with the pulse’s repetition frequency. The input power and fundamental frequency have lower sensitivity than other comb generators. This means a comb generator calibrated at a single power level and frequency can be used across a wide range of input power levels and frequencies.
