N9322C at a Glance
The Keysight N9322C spectrum analyzer is a portable, swept
spectrum analyzer with afrequency range of 9kHz to
7.0 GHz. It can be widely used in an electronic
manufacturing environment and in functional/final/QA test
systems.
Features
The Keysight N9322C spectrum analyzer primary features
and functions are described below:
• Power Measurement Suite
The built- in one- button power measurement suite offers
channel power, ACP, OBW, and TOI measurements, and
contains a Pass/Fail testing capability with a mask for
out- of- channel emissions measurement.
• Precision Frequency Reference (Option PFR)
The optinal OCXO frequency reference provides the precise
frquency measurement capability.
• Spectrum Monitor (Option MNT)
Provides the capability to analyze the stability of a signal
over time. The analyzer can be used to monitor the signal
capturing performance or intermittent event over extended
periods of time.

Helpful Tips 23
This chapter helps you in preparing the spectrum analyzer for use and
provides the information to start using the spectrum analyzer correctly.

Getting Started
Check the Shipment and Order List
12
Check the Shipment and Order List
After receiving the shipment, first check the shipment and
your order list. Inspect the shipping container and the
cushioning material for signs of stress. Retain the shipping
materials for future use, as you may wish to ship the
analyzer to another location or to Keysight Technologies for
service. Verify that the contents of the shipping container
are complete.
Shipping Problems?
If the shipping materials are damaged or the contents of the
container are incomplete, please contact the nearest Keysight
Technologies office to arrange for repair or replacement. You
will not need to wait for a claim settlement. If you must
return an analyzer to Keysight Technologies, use the original
(or comparable) shipping materials.
Options
Verify if that the shipment includes your ordered options by
checking the option label on the shipping container.
Unless specified otherwise, all options are available when
you order a spectrum analyzer; some options are also
available as kits that you can order and install/activate after
you receive the analyzer. Order kits through your local
Keysight Sales and Service Office.
At the time of analyzer purchase, options can be ordered
using your product number and the number of the option
you are ordering. For example, if you are ordering option
TG7, you would order N9322C- TG7.
If you are ordering an option after the purchase of your
analyzer, you will need to add a K to the product number
and then specify which option you are ordering. For
example, N9322CK- TG7.
