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.
