9. Using the insulated banana couplers, connect the positive lead (red) of the probe
under test to the positive output of the BNC-to-banana plug adapter and the
negative lead (black) to the negative or return output.
10. Set the oscilloscope scale factor to:
20 V/Div for HVD310x, HVD310xA, HVD3206, and HVD3206A
•
50 V/Div for HVD3605 and HVD3605A
•
11. Record the DMM reading to 0.01 mV resolution in the Test Record.
12. Multiply the measured output voltage recorded in step 11 by the actual probe
attenuation factor, then divide this number by the function generator output voltage
(probe input voltage) recorded in step 5. Subtract 1 from this number and multiply
the result by 100 to get the error in percent:
NOTE: The actual probe attenuation can be found by using the XStreamBrowser.
Follow the procedure below.
13. Record the answer to two significant places (± x.xx%) on line 13 in the Test Record.
14. Verify that the error ≤ 1.00%.
15. Decrease the oscilloscope scale factor to 5 V/Div.
16. Record the DMM reading to 0.01 mV resolution in the Test Record.
17. Multiply the measured output voltage recorded in step 16 by the actual probe
attenuation factor, then divide this number by the function generator output voltage
(probe input voltage) recorded in step 5. Subtract 1 from this number and multiply
the result by 100 to get the error in percent.
NOTE: Recheck the actual probe attenuation in the XStreamBrowser, as it will now
be a different value than in step 12. Click the Refresh button in XStreamBrowser if
the previous session is still open.
18. Record the answer to two significant places (±x.xx%) on line 18 in the Test Record.
19. Verify that the error is ≤ 1.00%.
20. This completes the Performance Verification Procedure. Complete and file the Test
Record as required to support your internal calibration procedure. If the criteria in
steps 14 or 19 are not met,
