HVD3102 and HVD3106 High-Voltage Differential Probes
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 attentuation can be found by using the XStream Browser. Choose
File > Exit to show the oscilloscope desktop, then double-click the XStream Browser icon. In
the locator field, enter the path "app.Acquisition.C1.InputB.HVD310x" (where x is your probe
model number). The value is shown next to PrAttenuation.
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 attentuation in the XStream Browser, as it will now be a
different value than in step 12.
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%.
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.
