Operating Hints
Some knowledge of operating the oscilloscope is helpful; however, these 
procedures are written so that little experience is necessary. The following two 
hints will speed progress of the testing.
Clear Display
When using many averages, it often takes awhile for a waveform display to 
stabilize after a change. When a control on the oscilloscope is changed, averaging 
automatically restarts. When just the input signal is changed, the oscilloscope 
must average new data with the old so it takes longer for the waveform to 
stabilize.
Press the Clear Display key while changing input signals. The oscilloscope will 
restart averaging and give a quick indication of the result of the signal change.
Averaging
Averaging is used to assure a stable signal for measurements. It is not necessary 
to wait for complete stability of the signal (averaging complete), as long as the 
measurement is well within the limits of the test.
Specifications
The specifications that apply to a particular test are given with the test 
procedure. For complete specifications and characteristics see the oscilloscope’s 
datasheet. The datasheet can be viewed by directing your web browser to 
www.keysight.com and performing a search for the oscilloscope’s model number. 
The datasheet will be in the “Library.”
Performance Test Procedures
Performance test procedures start with the next paragraph. Procedures may be 
done individually and in any order.
Fluke MET/CAL Procedures
Fluke MET/CAL procedures are available for the 8000 Series oscilloscopes.
The MET/CAL badge with "PROCEDURES AVAILABLE" signifies that Fluke has 
created Warranted MET/CAL procedures to verify the performance of this 
instrument using MET/CAL metrology software.  These procedures can be 
obtained from Fluke.  Please see http://www.fluke.com and search for MET/CAL 
for more information.
Let the oscilloscope Warm Up Before Testing
Allow the oscilloscope to warm up for at least 30 minutes prior to beginning performance tests. Failure to 
allow warm-up may cause the oscilloscope to fail tests.
