Calibrating and Adjusting
This chapter provides the self- calibration procedure for the Keysight
Technologies 8000 Series oscilloscope.
Hardware Adjustments
There are no hardware adjustments required for the 8000 Series oscilloscope.
Self Calibration Interval
The firmware calibration is the self cal (self calibration). Self calibration should
be done every year, or every 2,000 hours of operation, whichever comes first.
The self calibration uses signals generated in the oscilloscope to calibrate channel
sensitivity, offsets, and trigger parameters. You should run the self calibration
• yearly, or according to your periodic needs,
• when you adjust or replace the acquisition assembly or acquisition hybrids,
• when you replace the hard drive or any other assembly,
• when the delta temperature is more than
±
5
°
C different than the last
calibration, or
• after performing incoming performance verification and before performing
outgoing performance verification.
The need for self calibration will also depend on the environment in which you
use the oscilloscope.
Calibration Procedures
The procedures start with the next paragraphs. Unless specified elsewhere,
procedures must be followed in the order given. Display checks are optional
and independent of other procedures.
W A R N I N G SHOCK HAZARD!
Read the Safety information at the back of this guide before performing adjustment
procedures. Failure to observe safety precautions may result in electrical shock.
W A R N I N G INJURY CAN RESULT!
Install the fan safety shield (included in the Service Kit) if you remove the oscilloscope
cover. Without this shield, the oscilloscope fan blades are exposed and can cause injury.
