The Agilent/Keysight Technologies N9340B Handheld Spectrum Analyzer (HSA), 3 GHz provides you with a reliable, accurate and detailed picture of your communication 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.
When you test, you need fast data capture to help locate and identify elusive, transient interference signals. That is 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.
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.
With more wireless devices on the market requiring greater bandwidth usage, the ability to discriminate between different signals becomes more challenging. It is 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.
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.
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.
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.
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.
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.
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.
The new N9340B adds Spectrum Emission Mask (SEM) as a standard feature. SEM is 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 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.
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.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.
As with all the newest Keysight portable field equipment, operating under challenging bright sunlight or other difficult natural lighting conditions is no problem. The unusual 6.5'' TFT display with resolution of 640 x 480 pixels provides a superior, bright and clear trace for indoor and outdoor use. There is no need to operate in the shade.
The N9340B is installed with back-lit keys for night use. The user can see the keys clearly even in darkness. The user can adjust the brightness of keys and the duration of the key light. It offers the user the ability to easily operate N9340B at night.
The N9340B is installed with a light sensor in the front panel. The light-sensor can be activated to adjust the display brightness to adapt to changing lighting conditions.
Testing in the field often means operating away from main power supplies. Batteries need to have the longest possible operating time before recharging. You'll find an Keysight N9340B analyzer has superior power management, providing an impressive 4-hour battery operating time. It's easy to operate for an entire day in the field. There is an advanced, in-built battery management system. This helps extend the useful battery operating time typically up to four hours. With just one battery and a spare, or a quick recharging from any vehicle using the supplied auto-lighter charger, you are able to operate for an entire day away from a mains power source.
You will find that this Keysight analyzer is tough enough for military applications. Apart from its generally compact and rugged construction, the large rubberized grips wrap around both ends, providing additional robust protection from rough handling. The sealed keypad and screen are moisture resistant and dust proof. Of course, there is a protective carrying case that provides further protection for your analyzer.
