Service Strategy
Defective probes must be returned to a Teledyne Lecroy service facility for diagnosis and exchange. A
defective probe under warranty will be replaced with a factory refurbished probe. A probe that is not
under warranty can be exchanged for a factory refurbished probe. A modest fee is charged for this
service. A defective probe must be returned in order to receive credit for the probe core.
Troubleshooting
If the probe is not operating properly the problem may be the way in which it is used. Before assuming
the probe is defective, perform the following troubleshooting procedures:
1. Verify the Teledyne Lecroy oscilloscope is running firmware 4.3.0.0 or higher. The firmware
version of your oscilloscope can be verified by selecting Utilities > Utilities Setup > Status tab.
2. Waveform is inverted — Make sure the arrow on the slider is in the direction of the current
flow.
3. If the displayed signal shows a high offset — The probe locking lever may not be fully closed and
locked or the probe may need to be degaussed.
4. Attenuated signals or poor frequency response may be caused by contaminated core surfaces or
the probe locking lever may not be fully closed and locked.
5. No signal — Make sure the slider is closed and locked and that the ProBus connector is fully
engaged.
