Caracteristicas
The N9340A＊s RBW is the narrowest in its class. The narrow 3 dB 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 N9340A has the ability to resolve close adjacent signals with unequal amplitudes.
Moreover, the narrow RBW means that the spectrum analyzer introduces minimal noise itself, helping to further reduce noise levels and improve DANL.
- Frequency range: 100 kHz to 3 GHz
- RBW: 30 Hz to 1 MHz in 1-3-10 sequence
- VBW: 3 Hz to 1 MHz
- SSB Phase noise: 每 87 dBc at 30 kHz offset
- DANL: (10 MHz < fc ≒ 1.5 GHz)
- 每124 dBm
- 每144 dBm with preamp
- Sweep speed
- 10 ms to 1000 s, span 1 kHz
- < 120 ms at full span
- Amplitude accuracy: ㊣1.5 dB
Regardless of whether you are handling military communications, a Wireless Service Provide (WSP), or involved with spectrum management you need to avoid intermittent communication.
The N9340A provides you with a reliable, accurate and detailed picture of the spectrum over which you are working.
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 N9340A spectrum analyzer has a truly fast sweep time. It requires less time to measure across the bandwidth, to obtain more reliable test results 每 and helps 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 narrower resolution bandwidth (RBW) means your signal measurements are more reliable and you will have more confidence in your test results. The N9340A＊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.
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 N9340A analyzer proves its worth. The N9340A has one of the best sensitivity and selectivity specifications. The DANL is 每124 dBm with preamplifier off, or 每144 dBm with preamplifier (30 Hz RBW, 10 MHz < fc ≒ 1.5 GHz).
The phase noise is 每87 dBc at 30 kHz offset.
An optional preamplifier with 20 dB gain further improves analyzer sensitivity.
Speed at your fingertips
Spectrum bandwidth is a finite resource, therefore spectrum 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.
An important application of spectrum 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.
It is possible, these interfering signals could restrict critical communications of civil aviation and emergency services, which could potentially jeopardize lives.
