N9322C Basic Spectrum Analyzer


Easy on Your Budget Value

Achieve higher productivity on a smaller budget. That’s the challenge you face whether you are fine-tuning a new design, balancing throughput and accuracy on the manufacturing floor, providing maintenance service, or verifying field equipment.

It also necessitates that your choice of equipment provides just the right balance between price and performance. The modestly-priced, general purpose Keysight Technologies, Inc. N9322C basic spectrum analyzer (BSA) delivers.


Tough to Beat Performance, Efficiency, and Simplicity

When it comes to spectrum analyzers, the Keysight N9322C BSA defines a new generation of value-priced, general purpose instruments for the 9 kHz to 7 GHz frequency range. Features like proven testing efficiency, best-in-class usability, and the flexibility to adapt to new requirements are just a few of the reasons using the N9322C means you can rely on results.

Count on Performance

As market forces necessitate “cost down“ programs, compromising quality is not an option and reliability is paramount. Whether your application is consumer electronics R&D, manufacturing bench repair, RF-related education, or spectrum management projects, you need an affordable spectrum analyzer that is equipped with the essential functionality and the required performance.

Best-in-class RF performance translates to precision for every measurement task with the Keysight N9322C spectrum analyzer. With an annual aging rate up to ± 0.1 ppm, frequency drift is minimal so measurement accuracy is finely tuned. The typical displayed average noise level of up to –152 dBm makes identifying low-level signals quick and easy. Total absolute amplitude accuracy up to ± 0.6 dB ensures you can trust power measurement results.

The N9322C has redefined the meaning of “ease-of-use” for a basic spectrum analyzer. User-definable softkeys mean up to seven of the engineer’s most frequently used measurements setups are readily accessible. That makes switching between tasks more efficient and that helps improve higher throughput rates.

The optional task planner capability automates testing using pre-defined setup routines.


Rich features for budget-driven applications

Whether your application is consumer electronics R&D, manufacturing, bench repair, or RF-related education or spectrum management projects, you need a spectrum analyzer that provides essential functionality and required performance at an affordable price. The N9322C BSA is designed to be the right answer for you.


General purpose R&D

If the pressure to deliver new products on a tight schedule rests with you, you recognize the importance of achieving faster verification without compromising the reliability of test results. The N9322C has the essential capability you need to look into your design so you can quickly overcome development obstacles. Add to that measurement repeatability you can trust and you have an affordable resource to help you reach those time-to-market and on-schedule-delivery goals—and that peace of mind can be invaluable.

RF education

Every year a new crop of students rely on you to teach them the basic principles of spectrum analysis and you realize the most effective way for them to learn is with hands-on lab work. The constraint is often the number of available analyzers. Your solution is the N9322C. It has the basic functions students need to learn, at a price that allows you to get more spectrum analyzers than you thought possible.


Spectrum monitoring

The rapid release of new mobile devices is placing unprecedented demand on spectrum availability. Glitches in the system mean lost revenue and unhappy customers. You need the ability to detect low-level RF signals while simultaneously resolving closely spaced frequencies. You can depend on the N9322C. Included in its capability is its spectrum monitoring feature that allows you to record and playback captured traces, so you can quickly identify interfering signals arising from unwanted or unexpected transmissions.


Consumer electronics manufacturing

Maintaining the production line and ensuring dependable operation is part of your domain, and the demands are numerous. Topping the list are typically goals aimed at lowering product costs and shortening the production process. One method to reach these expectations is to shorten test times, without compromising product quality. The N9322C is your solution. With “just right” functionality it gives you the performance, reliability, and efficiency you need—at an attractively frugal price.


Bench repair

Repairing handsets (such as mobile phones) demands fast, cost effective test solutions. The N9322C is a functional and indispensable in low-cost bench repair applications—and for general purpose RF development and verification test. Detecting low-level signals while simultaneously resolving closely spaced frequencies is a fundamental requirement for RF testing. Employing one of the best combinations of sensitivity and narrow resolution bandwidths (RBW) ensures that the N9322C BSA readily handles these tasks.


Power measurements made easy

One of the most fundamental measurements performed by spectrum analyzers is the frequency domain measurement of RF power. However, detailed analysis of a signal often requires standards-defined spectral masks or more complex power, bandwidth, and detector measurement combinations.

With its one-button PowerSuite the N9322C makes it easy to measure channel power, occupied bandwidth (OBW), adjacent channel power ratio (ACPR), spectrum emission mask (SEM).

The channel scanner (Option SCN) enables the N9322C BSA to simultaneously scan a maximum of 20 different channels, calculate each channel’s power, and display the results in a bar or time chart.

Option SCN supports three scan modes:

  • Top N
  • Bottom N
  • List

Depending on the number of channels, the N9322C display toggles between horizontal and vertical views, making it easier to read results. A one-button logging function saves results in a .csv file.


ASK/FSK demodulation analysis

The ASK/FSK modulation has been widely adopted in low power, low data rate RF communications, because it ties low cost, high performance wireless connectivity with long battery life. Today, ASK/FSK modulation technology is embedded in a variety of products and systems, ranging from personal consumer electronics, automotive electronics, RFID and automatic meter reading, to giant industrial devices.

The N9322C with Option DMA offers a cost-effective ASK/FSK demodulation analysis solution for you.

It supports four display modes: symbol, waveform, ASK/FSK error, and eye diagram.

The demodulation metrics include carrier power, ASK modulation depth, ASK modulation depth, FSK frequency deviation, ASK/FSK error, ASK index, and more.
