General Safety Considerations
Warning
Warning
Caution
Before this instrument is switched on, make sure it has been
properly grounded through the protective conductor of the ac
power cable to a socket outlet provided with protective earth
contact.
Any interruption of the protective (grounding) conductor, inside
or outside the instrument, or disconnection of the protective
earth terminal can result in personal injury.
There are many points in the instrument which can, if contacted,
cause personal injury. Be extremely careful.
Any adjustments or service procedures that require operation
of the instrument with protective covers removed should be
performed only by trained service personnel.
Before this instrument is switched on, make sure its primary power
circuitry has been adapted to the voltage of the ac power source.
Failure to set the ac power input to the correct voltage could cause
damage to the instrument when the ac power cable is plugged in.

Introduction
Warning
This HP 8566B Tests and Adjustments Manual contains two main
sections: Performance Tests and Adjustments Procedures. This
chapter lists the required test equipment for both sections. The
performance tests provided should be performed for the following
reasons:
w
If the test equipment for the Operation Verification Program is not
available.
w
If the instrument does not pass all of the Operation Verification
tests.
n
For complete verification of specifications not covered by the
Operation Verification program.
The adjustment procedures should be performed for the following
reasons:
w
If the results of a performance test are not within the specifications.
w
After the replacement of a part or component that affects electrical
performance.
The adjustment procedures require access to the interior of the
instrument and therefore should only be performed by qualified
service personnel. There are voltages at many points in the
instrument which can, if contacted, cause personal injury. Be
extremely careful. Adjustments should be performed only by
trained service personnel.
Power is still applied to this instrument with the LINE switch in
STANDBY. There is no OFF position on the LINE switch. Before
removing or installing any assembly or printed circuit board,
remove the power cord from the rear of both instruments and
wait for the MAINS indicators (red
Capacitors inside the instrument may still be charged even if the
instrument has been disconnected from its source of power. Use a
non-metallic tuning tool whenever possible.
LEDs)
to go completely out.

Covered
This manual contains procedures for testing and adjusting HP
8566B spectrum analyzers, including those with Option 400 (400 Hz
operation), Option 462 (impulse bandwidths and 6 dB bandwidths),
and Option 857 installed. The procedures in this manual can also
be used to adjust HP 8566A spectrum analyzers that have been
converted into HP 8566B spectrum analyzers through the installation
of an HP 8566AB Retrofit Kit (formerly HP 8566A+OlK Retrofit Kit).
Operation Verification
Option 462
Instruments
A high confidence level in the instrument’s operation can be achieved
by running only the Operation Verification Program, since it tests
most of the instrument’s specifications. It is recommended that the
Operation Verification Program be used for incoming inspection and
after repairs, since it requires much less time and test equipment.
A description of the program can be found in the Installation and
Verification manual.
Option 462 instruments require that the performance tests and
adjustment procedures listed below be performed instead of their
standard versions included in chapters two and three. Information on
Option 462 versions is located in Chapter 4, Option 462.

Introduction
Verifkation
Specifications
of
The procedures in this section test the instrument’s electrical
performance using the Specifications in the Installation and
Verification Manual as the performance standards. None of the
tests require access to the interior of the instrument. The manual
Performance Tests provided in this section should be performed only
if semi-automatic test equipment (for Operation Verification) is not
available or the Performance Test is not in the Operation Verification
Program. (Refer to the Installation and Verification Manual for
information on Operation Verification.)
When a complete verification of specifications is required, proceed as
follows:
1. Run the Operation Verification Program.
2. The Operation Verification Program verifies compliance with
specifications of all tests it performs. The tests not performed by
the Operation Verification Program must be done manually and are
as follows:
n
Sweep Time Accuracy (including Fast Sweep Time Accuracy)
n
Noise Sidebands
n
Harmonic and Intermodulation Distortion
n
Image, Multiple, and Out-of-Band Responses
n Frequency Reference Error
n
Center Frequency Readout Accuracy
If the results of a performance test are marginally within
specification, go to the Adjustments section of this manual and
perform the related adjustments procedures. When an adjustment is
directly related to a performance test, the adjustment procedure is
referenced under RELATED ADJUSTMENT in the performance test.

Description
Equipment
Procedure
A synthesized signal source that is phase-locked to a known frequency
standard is used to input a signal to the analyzer. The frequency
readout of the analyzer is compared to the actual input frequency
for several different frequency settings over the analyzer’s range.
The signal source is phase-locked to a standard known to be as
accurate as the analyzer’s internal frequency reference to minimize
the “frequency reference error X center frequency” term of the
specifications.

Note
The spectrum analyzer CENTER FREQUENCY readout may fall
outside of the specified limits if the internal frequency reference
of the analyzer has not been calibrated within the past year.
To
eliminate the “frequency reference error X center frequency” error,
the analyzer’s 10 MHz Frequency Reference Output (on the rear
panel) may be substituted for the frequency standard.
