6 Troubleshooting
When the above dialog box appears, and clicking Retry can’t enter the main program, only Run Demo is available, then
follow below steps to check:
Check the Power of LA is on or off.
Check the USB connector is inserted into the USB interfaces of PC and LA properly or not.
Check whether other USB device can run normally or not in this USB Port; if yes, then the USB Port has no problem; if
not, the USB Port maybe damaged.
Please try another USB cable.
The operating system maybe in the process of hardware setting, please click Retry again later.
Press the Start button to start the LA. If the LA can’t trigger or sample properly, or can’t stop, or can’t acquire the right
waveform:
1. Please make sure the connecting line of each channel is connected with the object under test properly.
2. Please make sure the ground line of channel is connected with the ground end of the object under test properly.
3. Please make sure the setting of trigger level is in accordance with the signal level of the object under test.
4. Please make sure the sampling frequency is 4 times higher than that of the object under test.
5. Please make sure the trigger setting is proper. The signal of the object under test maybe can’t meet the trigger
condition, please simplify the trigger condition or change the settings.
6. Please make sure the setting of trigger count is not too large.
7. Please make sure the setting of trigger page is not too large.
8. Please check it is sampling from external signal or not. External signal maybe can’t provide enough signal, so try
sampling from the internal signal.
Please make sure the driver is installed.
