Designed for bench and system
use, the HP 8566B offers
superior measurement speed,
microwave frequency accuracy,
and sensitivity. Measure
low-level signals up to 22
with narrow resolution
bandwidths. Synthesizer
stability virtually eliminates
long-term drift and residual FM.
The Spectrum Analyzer
That Keeps Getting Better
Frequency range is 100 Hz to
22
with a dc-coupled input.
Preselected external mixers
extend this coverage from 26.5 to
75
Other external mixers
allow measurement to 325
An internal bus and microcom-
puter control make possible
many powerful operating and
data processing features, as well
as flexibility under computer
control. Sixteen Kbytes of user
RAM are available for storing
trace data, instrument states,
and custom downloadable
programs
All displayed
information can be sent directly
to an HP-IB plotter when
sweeptime is greater than or
equal to 20 ms.
Accurate Measurements
Amplitude measurement range
extends from
to -135
with a 90 calibrated display.
Less than 1 x
frequency reference error and
the spectrum analyzer selectivity
allow high frequency accuracy
even when you are measuring
small signals in the presence of
large ones.
Turbo Speed Option
Already
a world leader in
measurement speed, the
HP 8566B can be made even
faster with Option 002, which
nearly doubles the internal
processing speed of the analyzer.
Some measurements can be
made up to 50% faster, and
overall throughput is typically
improved by 5 to 25%. (Sweep
speed is not affected by
Option
The Turbo option is compatible
with all HP 8566B accessories,
and it can be added to any
HP 8566B without affecting
specifications. (An HP 8566A
must first be upgraded to an
HP 8566B.)
Accessories and Options
By adding measurement
accessories and options, the
HP 8566B spectrum analyzer
fits into many applications,
including electromagnetic

broadband signal surveillance,
and component

Commercial and MIL EM1
Receivers
The HP 8566B spectrum analyzer
forms the heart of two powerful and
flexible EM1 receivers. These receivers
are ideal for commercial and military
EM1 compliance testing from 20 Hz
to 40
Test Systems Tailored to
Your Needs
For EM1 troubleshooting and

The HP 8571A receiver is optimized
for military EM1 testing, making both
peak and average detection measurements using impulse bandwidths. The
HP 85728 includes all the features
and capabilities of the HP 85718, but
adds quasi-peak detection and specialized IF bandwidths for commercial
compliance measurements.
Both receivers offer

Accessories That
Enhance Performance
Millimeter Mixers
Preselected Mixers
The HP 11974 series preselected
mixers eliminate the need for
consuming signal identification
routines at millimeter
frequencies. With preselection,
no images or multiples are
generated to confuse measure-
ments. These external mixers
allow you to quickly locate true
signals, and they simplify
software development for
automated measurements.
The HP 11974 series mixers are
available in four bands covering
26.5 to 75
Preselected mixers eliminate images and multiples.
Harmonic Mixers
The HP 11970 series waveguide
mixers are general-purpose
external harmonic mixers. They
offer flat frequency response and
low conversion loss without
requiring external dc bias or
tuning adjustment. The HP 11970
series mixers are offered in six
bands covering 18 to 110

Tracking Sources
Add high dynamic range scalar
measurement capability to the
HP 8566B. The HP 856448 and
856458 portable tracking
sources allow you to use your
spectrum analyzer for measuring
transmission and reflection
characteristics of devices.
You can also characterize
harmonic distortion,
intermodulation distortion,
spurious products, and more.
The tracking sources give the
HP 8566B dynamic range greater
