NOTE. Steps 14 though 17 must be performed once for each input channel under test.
15. Push Add Measu
rement on the lower menu.
16. Use Multipurp
ose knob “b” to select the Mean measurement. If needed, use Multip urp ose knob “b” to select
the channel input being tested.
17. Push OK Add Measurement on the side menu, and then Menu Off on the front panel.
18. View the m ean measurement value in the display and enter that mean value as the test result in the test record. (See
page 38, DC Balance Tests.)
NOTE. Trans
late the mean value into d ivisions for use in the test record. To do this, divide the voltage value by the vertical
scale value. (e.g.0.2 V / (1 V / division) = 0.2 divisions)
19. Repeat step 7 and step 18 for each volts/division value listed in the results table.
20. P ush the channel button on the front panel, then change the oscilloscope bandwidth (for example, 20 MHz, 150 MHz, or
Full), an
d repeat step 7, step 18, and step 19.
21. For 1 M co
upling, change the oscilloscope termination to 1 M and repeat steps 5 through 20.
22. Repeat s
teps 3 through 20 for each channel combination listed in the test record and relevant to your model of
oscilloscope (for example, 1, 2, 3,or4).
NOTE. The BNC 50 Ω terminator needs to be moved to next input channel.
23. For 75 coupling, change the oscilloscope termination to 75 and repeat steps 5 through 20.
NOTE.
The BNC 50 Ω terminator needs to be moved to next input channel.
24. Repe
at steps 3 through 20 for each channel combination listed in the test record and relevant to your model of
oscilloscope (for example, 1, 2, 3,or4).
NOTE. The BNC 50 Ω terminator needs to be moved to next input channel.
This completes the procedure.
