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 sensitiv-

ity and selectivity specifications. The

DANL is –124 dBm with preamplifier

off, or –144 dBm with preamplifier

(30 Hz RBW, 10 MHz < fc

≤

1.5 GHz).

The phase noise is –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 regula-

tory authorities responsible for

administering frequency allocation

require service suppliers and network

operators to perform routine monitor-

ing 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.

Some sources of interference are

more intermittent than regular

transmissions. Such spurious signals

can be hard to eliminate because it is

difficult to identify and isolate them.

With an impressively fast sweep – a

minimum non-zero-span sweep time

of 10 ms – an Agilent N9340A

handheld spectrum analyzer increases

the probability of you detecting and

capturing spurious or transient

signals.
