Checking Probe Attenuation In Xstream Browser - Teledyne Lecroy HVD3000 Series Operator's Manual

get the error in percent:
NOTE: The actual probe attenuation can be found by using the XStream Browser. 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 attentuation in the XStream Browser, as it will now be a
different value than in step 12. Click the Refresh button in XStream browser 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%.
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.

Checking Probe Attenuation in XStream Browser

Probe attenuation and other values can be found by using the XStream Browser application
that is installed with the oscilloscope firmware.
1. Choose File > Minimize to show the oscilloscope desktop, then double-click the XStream
Browser icon.
2. From the browser menu bar, choose File > Connect to Local Instrument.
3. Navigate to LeCroy.XStreamDSO > Acquisition > C1 > InputB > HVDxxxx (where xxxx is
your probe model number). The value is shown next to PrAttenuation.
4. Close XStream browser and touch the oscilloscope icon (bottom right of desktop) to
return to the oscilloscope software.
NOTE: These steps are tailored to the Performance Verification procedure. You can find any
value at any time by changing the path to reflect the probe's actual input channel and row (Cx >
Input A|B).
