8 Agilent U9391C/F Comb Generator Operating and Service Manual
1 Introduction
Product Overview
The U9391C/F comb generator was designed as a phase
reference standard for the Agilent PNA- X nonlinear vector
network analyzer (NVNA). It was developed to provide
precision phase calibration, traceable to the National Institute
of Standards and Technology (NIST).
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/F comb
generators as precision phase calibration standards. Comb
generators generate frequency harmonics at integer multiples of
an RF input signal.
Generally, comb generators available in the open market today
are made with SRD diodes, U9391C/F comb generators are
based on Agilent InP MMIC technology to ensure superior phase
stability of the combs.

Introduction 1
Agilent U9391C/F Comb Generator Operating and Service Manual 9
The U9391C/F comb generator offers the advantage of wide
bandwidth 10MHz to 26.5GHz/50GHz output and small
minimum tone spacing (10MHz). When driven by low phase
noise sources, this comb generator will operate at frequencies
lower than 10MHz, but performance is not guaranteed. 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. It comes with the option of
a female or male output connector.
U9391C/F modules are solid state devices which provide
excellent phase and amplitude flatness in the combs making
them ideal for use in phase calibration applications. A built- in
frequency divider, selectable via the PNA- X, reduces the noise
of the combs. 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

1 Introduction
for characterizing non- linear devices. This module has a trigger
output which enables synchronization with the pulse’s
repetition frequency. Calibration data stored inside the
U9391C/F can be accessed directly by the PNA- X via the USB
interface to be used in phase calibration.
Key Features of Agilent U9391C/F Comb Generator
•Excellent amplitude and phase flatness enable it to be used
as a precision calibration phase reference standard for the
NVNA
•NIST traceable phase calibration guarantees a reliable
reference to international standards
•Embedded calibration data can be easily accessed via the
plug- and- play USB interface
•The USB interface further facilitates frequency divider
control and calibration data retrieval via the PNA- X.
•Rugged 3.5mm/2.4mm bulk- head connectors guarantee high
repeatability throughout multiple connects and disconnects.
Compatible Agilent Network Analyzer
The U9391C/F are designed to operate with Agilent PNA- X
nonlinear vector network analyzer (NVNA). The U9391C/F
modules are controlled by the PNA- X network analyzer via a
USB connection with options required: 400, 419, 080, 510.
PNA- X network analyzers can be upgraded to perform
non- linear component characterization.
