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, accu-
rate 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 mini-
mal 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 pream-
plifier 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.
