Agilent N9340B Handheld Spectrum Analyzer

Agilent N9340B Spectrum Analyzer

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 shapefactor 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.
