The 8563E is Agilent's 26.5 GHz spectrum analyzer. A spectrum analyzer measures the spectral power of known and unknown signals. It collects information such as the amplitude of the input signal relative to its frequency. As a frequency analyzer, the primary use of a spectrum analyzer is to record and analyze the spectral components of electrical input signals and other signals.

Additional features:

Continuous sweep from 30 Hz to 26.5 GHz

Fast digital resolution bandwidths of 1, 3, 10, 30, and 100 Hz

Standard measurements for adjacent channel power, channel power, carrier power, percent occupied bandwidth, and time-gated measurements

Precision timebase and 1 Hz counter resolution

MIL-T-28800 ruggedness

Measurement characteristics for digital radio and phase noise measurements

Internal mixing: 30 Hz to 26.5 GHz

External mixing: 18 GHz to 325 GHz

The Agilent 8563E portable microwave spectrum analyzer provides the measurement capabilities and performance previously found in larger, more expensive benchtop analyzers. This analyzer has a standard frequency range of 9 kHz to 26.5 GHz (preselected from 2.75 GHz to 26.5 GHz), with an optional low-end frequency coverage of 30 Hz.
