Introduction
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.
Warning
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
LEDs)
to go completely out.
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.
