Regardless of whether you are manufacturing a wireless mouse, keyboards,
GPS devices, or RF components such as mixers, filters or amplifiers, you need
to measure their RF characteristics to insure they work properly within their
design parameters like frequency bandwidth and output power range. Too little
RF power may decrease the wireless operating distance, while too much power
can drain batteries quickly, reducing operation time and cause excessive heat in
the device.
In today’s competitive world, you need to verify your product’s RF performance
fast and accurately as well as lower your cost of ownership. The affordable
N9320B is designed to help achieve all these goals. So, why not take a closer
look at the N9320B spectrum analyzer?
Boost productivity by decreasing test time
The throughput rate of a test station is generally one of the key factors limiting
the productivity of a manufacturing line. You almost always want to test your
products in the shortest possible time. The sweep time of a spectrum analyzer
is often the most important performance specification contributing to your RF
analysis test time. The N9320B analyzer provides you with 10 ms non-zero span
sweep time, the fastest in its class.
Testing and validating your products with confidence
The N9320B equipped with a new digital IF section tests your product with
improved frequency and amplitude accuracy and stability. It provides essential
information for your products’ performance and characteristics with increased
confidence.

Simplify Common Measurement Tasks
When you find yourself having repeatedly to make the same type of complex
measurement or measurement sequence, it is useful to know that some
shortcuts are available. That's what we have provided for you in the N9320B
spectrum analyzer.
The N9320B spectrum analyzer continues the Keysight tradition that test equipment should be easy to set up and simple to use. Those familiar with other
Keysight spectrum analyzers will find a similar user interface in the N9320B,
allowing for a shorter learning curve and easier operation.
One button auto-tuning allows you to quickly find and accurately analyze the
highest level signal anywhere in the analyzer’s frequency range. Centering this
signal on the screen, the analyzer simultaneously optimizes the frequency span,
resolution and video bandwidths, auto-scales the amplitude, sets a marker on
the signal peak and displays the measurement results.
Power measurements made easy using the one-button
measurement suite
You will find that the one-button power measurement suite shortens routine
test set up time by simplifying the keypad/menu selection.
Selecting these one-button routines directly from the softkey menu also helps
ensure accuracy and repeatability of the test set up and measurement no matter
who presses the button.
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/detector measurement combinations.
Channel power
Precise, rapid integrated channel power with computed power spectral density
utilizing the RMS average detector.
Occupied bandwidth
Selecting the percentage of the signal’s power to be measured places markers
at the upper and lower frequencies of the waveform representing the bandwidth
utilized by that percentage of power.
Adjacent channel power (ACP)
Fast, accurate simultaneous filtered RMS power measurement of a carrier
relative to its leakage in up to six offset bands or channels.

Simplify Common Measurement Tasks (continued)
Bench repair
An effective, professional
bench repair tool
Most bench repair tasks
demand fast, cost effective
test solutions. Being small and
lightweight, the N9320B spectrum analyzer is as functional
and indispensable in low-cost
bench repair applications as it
is for field troubleshooting.
Detecting low signal levels
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 an N9320B spectrum
analyzer will readily handle
these tasks.
Spectrum emission mask (SEM)
The spectrumemission mask (SEM) is a set of complex limit lines forming a
mask for out-of-channel emissions measurement. The SEM is defined relatively
to in-channel power. You can set the parameters of the main channel, out of
channel frequency bands and the limit lines. Included is Pass/Fail testing for the
overall spectrum emission mask and each individual out-of- channel frequency
range.
Of course, you retain the flexibility to tailor each measurement task to your
specific needs when necessary. And you’ll find it easy to distinguish between
signals having large level differences since the N9320B has one of the widest
dynamic ranges for an analyzer in its price range.
High accuracy power measurements
The N9320B now supports high accuracy, USB plug-and-play power measurements as standard when connected to a Keysight U2000 series USB power
sensor. Make true average power measurements for all signal types with wide
dynamic range up to 18 GHz with just the push of a button. The Keysight U2000
series USB power sensors require no external power supplies and with internal
zeroing eliminate the need for external calibration. Without the need for additional boxes, the user can easily set up, calibrate and control the power sensor
via the analyzer’s USB port. Two display modes are available: either the meter or
the chart mode to log power measurements over time.

Simplify Common Measurement Tasks (continued)
EMI filters now available (Option EMF)
One of the criticalsteps for product development in order to sell electronic
products on the commercial market, is theymust pass EMC (Electro Magnetic
Compatibility) requirements. Waiting until the end of the development cycle to
find out whether or not a product passes regulatory agency requirements can be
an expensive gamble. Failing topass can result in costly redesign, delays while
waiting for additional EMC compliance testing and results and apostponement
to your product introduction.
N9320B offers limit line for pass/fail
The detailed metrics provides you with the
complete understanding of the AM signal
Therefore, it is important to perform EMI (Electro Magnetic Interference)
pre-compliance (Electro Magnetic Interference) pre-compliance tests to find
potential EMC problems during the product development phase,where they
can be more easily corrected, and prior to sending your product to a regulatory
agency or EMC test facility for final verification. Pre-compliance measurements
are intended to give you an approximation of the EMI performance of your
products. This can provide you with higher confidence in passing regulatory
agency requirements.
Now, the N9320B provides you with optional CISPR EMI filters (–6 dB), covering
resolution bandwidths 200 Hz, 9 kHz, 120 kHz and 1 MHz for enhancing precompliance measurements. Installing option EMF enables EMI pre-compliance
measurements in CISPR-specified bandwidths and these tests can bemadeusing
the N9320B’s positive peak detector in a simple and fast way.
AM/FM demodulation analysis (Option AMA)
The detailed metrics provides you with
the complete understanding of the FM
signal
When you aremakingmodulation depth or frequency deviation measurements for
AM or FM devices, the N9320B with its optional AM/FM modulation analysis
shows the metrics you need, including carrier power,modulation rate, AM
depth/FM deviation, SINAD and carrier frequency offset. User definable limits
provide Pass/Fail indicators for carrier power, AM modulation index or FM
deviation, and carrier frequency offset. The user can save the waveforms with
metrics for reporting as wellas the set-up parameters for future measurements
or analysis.
Besides the AM/FM demodulation analysis (option AMA), the N9320B provides
AM/FM tune and listen in spectrum analysis mode as a standard function.
ASK/FSK demodulation analysis (Option DMA)
The FSK demodulation metrics with
waveform view
Optional ASK/FSKmodulation analysis is now available. Amplitude Shift Keying
(ASK) is used in RFID and optical systems. Frequency Shift Keying (FSK) is
used inmany applications including cordless phone, paging systems and RFID.
N9320B with option DMA supports four display modes: Symbol, Waveform,
ASK/FSK Error, and Eye Diagram. Included is Pass/Fail testing for carrier
power, ASK modulation depth/FSK frequency deviation. The metrics you need
are shown, including carrier power, ASK/FSK error, ASK depth/FSK frequency
deviation, and ASK index etc. For reports and future measurements the waveform with metrics and setup parameters can be saved.
