Know your spectrum

Regardless of whether you are handling military communications, a Wireless Service

Provider (WSP), or involved with spectrum management you need to avoid impaired communication. The N9340B provides you with a reliable, accurate and detailed picture of your communication spectrum.

Optimize your test time versus accuracy

When you test, you need fast data capture to help locate and identify elusive, transient interference signals. That’s why every N9340B spectrum analyzer has a truly fast sweep time. It requires less time to measure across the spectrum, to obtain more reliable test results and to help you achieve more for the same investment of time and money.

Gain confidence in your test results

Spurious signals and noise are of great concern to all network users. A superior combination of low displayed average noise level (DANL) and single sideband (SSB) phase noise coupled with a narrow resolution bandwidth (RBW) means your signal measurements are more reliable and you will have more confidence in your test results. The

N9340B’s low DANL and SSB phase noise helps you detect very low-level signals (spurs or noise) which are close to the carrier. You will avoid missing these difficult-to-identify signals, which would otherwise lead to an insufficient or even incorrect understanding of the spectrum.

The N9340B’s RBW is the narrowest in its class. The narrow 30 Hz bandwidth of the analyzer ensures that it is even easier to identify, resolve, and measure two signals that are close together. Additionally, with a resolution filter shape-factor of less than 5, the

N9340B has the ability to resolve closely spaced signals with unequal amplitudes.

Moreover, the narrow RBW means that the spectrum analyzer introduces minimal noise itself, helping to further reduce DANL and improve sensitivity.

Superior sensitivity

With more wireless devices on the market requiring greater bandwidth usage, the ability to discriminate between different signals becomes more challenging. It’s under such demanding conditions that the superior performance of an N9340B analyzer proves its worth. The N9340B has one of the best sensitivity and selectivity specifications. The

DANL is –124 dBm, or –144 dBm with the optional preamplifier (30 Hz RBW, 10 MHz < fc

≤ 1.5 GHz). The optional preamplifier adds 20 dB gain for improved analyzer sensitivity.

Speed at your fingertips

The RF spectrum is a finite resource, therefore its usage requires management. Most regulatory authorities responsible for administering frequency allocation require service suppliers and network operators to perform routine monitoring of signal power and transmission frequency stability.

N9340B is now equipped with powerful features to address field applications using a handheld spectrum analyzer. An analysis is identifying interfering signals. These often arise from illegal transmissions, and may cause impairment of services for authorized users, often resulting in financial loss. These interfering signals could possibly restrict critical communications of civil aviation and emergency services, which could jeopardize public safety.

Spectrogram

Now you can take advantage of the spectrogram display to view the behavior of varying signal parameters over time. The N9340B includes spectrogramas a standard feature.

The scrolling three-dimensional display is noted for its ability to track the frequency and power behavior over the time, particularly intermittent signals. The user can use spectrogramto analyze the stability of a signal over the time, or to identify intermittent interference signals in communications systems.

There are two markers for the user to identify power versus frequency and time. Also the time interval between two consecutive colored rows can be adjusted.When amarker is put on the spectrogram, the N9340B can display the trace for the time of the selected marker.

The spectrogramdata and screenshots can be saved and recalled for later analysis or reporting.

N9340B applications for field test

– Aerospace and defence:

Radio and radar test, interference analysis, on-site repair

– Wireless service providers:

Interference analysis, on-site repair

– TV and broadcasting: Interference analysis, channel power check

– Spectrum management authority:

Spectrum monitoring

The spectrogram gives the three-dimensional display of power, frequency and time.


Extended spectrogrammonitoring (Option INM)

Option INM extends the N9340B spectrogram capability further with the ability to continuously monitor and save spectrogram data over time not only to the analyzer’s internal memory or a USB flash drive, but also directly to a PC. With option INM users can save more than 1,500 continuous frames of data depending on the size of the USB flash drive or PC memory.

Option INM also supports an Automatic Save function. The N9340B can save the spectrogram at a user specific time or at a set interval of frame. All the small files with the same prefix can be combined into one file using N9340 PC Software, making analysis easier.

The user can choose among the 3 display modes: spectrogram only, spectrum trace only or the combination of a spectrogram and a spectrum trace in one screen. Limit lines with pass/fail functionality is also available in this measurement. The N9340B will identify the failed frame of spectrogram data with a red mark. The Pass/Fail test can also provide alerts. Users may use marker to find the previous/next frame failed data to quickly find the offending event or interference. The spectrogram data may be played back for review on either the analyzer’s display or on a PC utilizing N9340B PC Software.

With the option INM, the Keysight N9340B spectrum analyzer can provide unattended monitoring of communication systems capturing performance or intermittent events like interference over extended periods of time – days rather than hours. The option INMcan provide additional value for the wireless network communication system managers, hospital administrators, etc. as well as police and homeland security by recording spectrogram measurement results over time.

The N9340B INM shows spectrogram and spectrum trace on the same screen.


IBOC measurements (Option IBC)

Option IBC equips the N9340B with in-band on-channel (IBOC) measurement capability through a dedicated measurement personality and selected hardware improvements.

IBOC technology is a method of transmitting digital and analog radio broadcast signals

(AM and FM) simultaneously on the same frequency. This HD Radio™ version of hybrid digital/analog technology is the only one approved by the FCC for U.S. radio broadcast stations.

The IBC option adds enhanced SSB phase noise for IBOC AM measurements and a noise cancellation process for improved IBOC FM measurement margins. IBOC-AMcovers

530 kHz to 1.7 MHz and IBOC-FMcovers the 87.5 MHz to 108 MHz frequencies.

Option IBC has built-in FCC and NRSC (National Radio Systems Committee) spectral emission masks for quick compliance measurements with visual and audible pass/fail indicators.

N9340B IBC also supports a one-button auto-tune function that greatly simplifies the otherwise complex user setup required to capture and measure IBOC signals of interest. The auto-tune function will automatically set the frequency span, RBW, Average and Detector types, etc. It only takes seconds for the auto-tune function to display the correct measurement results.

The included Channel list feature enables users to easily create and recall setup and measurement parameters for single or multiple broadcast frequencies and channels. The user no longer needs to spend time remembering numerous channel setups but can simply load the desired channel from the list to start a measurement. The Channel list can be loaded, copied and deleted.

N9340B is the industry’s first handheld spectrum analyzer with a dedicated IBOC measurement mode. The option IBC is not available as an upgrade and must be ordered at the time of instrument purchase.

One-button measurement

The Keysight N9340B supports one-button measurements of occupied bandwidth, channel power and adjacent channel power ratio. This virtually eliminates set-up time in the field.

Occupied bandwidth (OBW)

An occupied bandwidth measurement integrates the power of the displayed spectrum and puts one pair of vertical lines at the frequencies between which the interested signal is contained.

An N9340B spectrum analyzer supports two ways to measure the occupied bandwidth, in percentage or in dBc.

The occupied bandwidth measured in percentage.

The occupied bandwidth measured in dBc.


Channel power

Use channel power to measure both power and power spectral density in a user-specified channel bandwidth. One pair of vertical lines on the display indicates the edges of the channel bandwidth.

It is quick and easy to set center frequency integration bandwidth, and channel bandwidth.

Adjacent channel power ratio (ACPR)

Wireless service providers need to minimize the interference caused by power leaking into adjacent transmit channels. Adjacent channel power ratio measurements help to check for signal leakage and the identification and control of sources of interference.

Center frequency, main channel bandwidth, adjacent channel bandwidth, and channel space can eadily be set.


Spectrum emission mask (SEM)

The new N9340B adds Spectrum Emission Mask (SEM) as a standard feature. SEMis a mask for out-of-channel emissions measurement. The SEMis defined relative to in-channel power.

The user 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. The N9340B will trigger the failure indicator once any measurement result violates the mask.

Also displayed are the main channel power and the power level metrics relative to in-channel power for each out-of-channel frequency range. The user can save the spectrum scan, the mask, the data or screenshot for later analysis and reporting.

The spectrum emission mask shows the main channel power and the power level vectors relative to in-channel power for each out-of-channel frequency range.


AM/FM modulation analysis (Option AMA)

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 in 4 cases: higher than carrier power, larger than AM modulation index or FM deviation, lower than AM modulation index or

FM deviation, or larger than carrier frequency offset. The user can save the waveforms with metrics for reporting as well as the set-up parameters for future measurements or analysis.

The detailed metrics offer you the complete understanding of the AM.

The detailed metrics offer you the complete understanding of the FM.


ASK/FSK modulation analysis (Option DMA)

Optional ASK/FSK modulation analysis is now available. Amplitude Shift Keying (ASK) is used in RFID and optical systems. Frequency Shift Keying (FSK) is used in many applications including cordless phone, paging system and RFID.

N9340B with option DMA supports 4 display modes: Symbol, Waveform, ASK/FSK Error, and Eye Diagram. Included is Pass/Fail testing of higher than carrier power, higher than

ASK modulation depth/FSK frequency deviation, lower than ASK modulation depth/FSK frequency deviation and higher than 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.

The Eye Diagram of ASK also shows the metrics with detailed parameters.

The Waveform of FSK also shows the metrics with detailed parameters.


High accuracy power measurement

The N9340B now supports high-accuracy, USB plug-and-play power measurements as standard when connected to an 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 USB 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 meter/sensor via the analyzer’s USB port. The N9340B can collect, display and save the power meter results.

The analyzer also provides Pass/Fail testing with user set upper and lower limits and a Pass/Fail indicator. Test results are shown in dBm and W when making absolute measurements and in dB and percentage when measurements are relative. Two display modes are available: Meter or the Chart mode to log power measurements over time.

N9340B supports Meter and Chart mode to display the results of power measurements.

N9340B supports U2000 series USB power sensors for high accuracy power measurement.


Field strength measurement

Electric field strength measurements are frequently required for field testing of transmitter and antenna coverage. Field strength measurements are now a standard function in the N9340B. Calibrated field strength measurements are easy to make once the antenna factors are loaded into the analyzer via the provided PC software based antenna template. Either field strength (in dBμV/m, dBmV/m, or V/m) or power flux density (in dBm/m or W/m) can be displayed. With the amplitude offset function, the user can correct gain or loss. And finally together with the user-definable multi-limit line function, the N9340B offers the user quick and convenient field strength measurements and analysis.

The field strength measurement automatically takes into the account of the antenna factor. The antenna table is definable by the standard N9340B PC software.


Channel table

For the users who prefer to tune the spectrum analyzer according to channel numbers rather than center frequency, you will find the new Channel Table feature easy-to-use.

The Channel Table includes the major wireless communication standards, such as AMPS,

GSM/EDGE/GPRS, CDMA, CDMA2000 etc. The Channel Table can also be edited by the user with the included N9340 PC Software. The revised Channel Table can be downloaded to the analyzer via a PC USB cable or a USB memory stick.

The channel table offers the ability to tune N9340B according to channel numbers.

The channel table is editable by N9340B PC software.


A standard soft carrying case provides further protection for your analyzer.
