please check each possible solution listed below it. If the issue is not resolved, please
contact your dealer or Teledyne LeCroy directly.
1.
The screen remains dark after power on

2.
After the signal is sampled, there is no corresponding waveform displayed

3.
The voltage amplitude measured is higher or lower than the actual value (the
error usually occurs in use of the probe)
Verify that the attenuation coefficient setting of the channel in use matches with the
attenuation ratio of the probe.
4.
A waveform is displayed but is not stable

Check if the power is correctly connected.
Check if the power switch is faulty.
Check whether the fuse is burned out. If the fuse is defective please replace with
a fuse of the same size and ratings. If you have questions, please contact
Teledyne LeCroy support.
Restart the instrument after completing the steps listed above.
If these steps do not solve the problem, please contact Teledyne LeCroy.
Check to make certain the probe is not faulty.
Check to make certain the probe is correctly connected to the BNC input
connector.
Verify that the probe is correctly connected to the item-under-test.
Verify that there is signal generated from the item-under-test.
Resample the signal.
Check the trigger source: check whether the 'Source' in menu of 'TRIG' is the
actual operating channel.
Check to see if the waveform is similar to what is expected. Make certain that the
time base is in the expected range. It is common to not see a signal if the time
base is set to sweep too fast.
Check the trigger type: 'Edge' trigger suits to general signals and 'Video' trigger
suits to video signals. The correct trigger type setting can be important in
obtaining a stable display.
Change the setting of trigger hold-off.
