ADP30x Probe
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 1000 and
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:

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 100 and
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.

18. Record the answer to two significant places (±x.xx%) on line 18 in the Test
Record.
19. Verify that the error is ≤ 2.00%.
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, contact your local Teledyne LeCroy service
center.
