Keysight U9391C Comb Generator, 10 MHz to 26.5 GHz

Discontinued

The Keysight U9391C has been replaced by newer models

The Keysight U9391C Comb Generator is developed to provide precision phase calibration, referenced to the National Institute of Standards and Technology (NIST) standard, for non-linear measurements using the PNA-X nonlinear vector network analyzer (NVNA) 1. NVNA component characterization software converts a 4-port PNA-X with Option 510 into an innovative, high-performance, non-linear network analyzer which uses U9391C comb generators as a precision phase calibration standard. Comb generators generate frequency harmonics at integer multiples from an RF input signal. Generally, comb generators available in the open market today are made with SRD diodes, U9391C comb generators are based on Keysight InP MMIC technology 2 to ensure superior phase stability of the combs.
