Troubleshooting
Table 12 Equipment Required to Troubleshoot the Oscilloscope
To check out the oscilloscope
1 Disconnect any external cables from the front panel.
2 Disconnect the power cord, then remove the cabinet following the instructions
on page 73 for Keysight 6000L Series models.
3 Connect the power cord to the rear of the oscilloscope, then to a suitable ac
voltage source.
The oscilloscope power supply automatically adjusts for input line voltages in
the range of 100 to 240 VAC. Ensure that you have the correct line cord. The
power cord provided is matched to the country of origin.

CAUTION
USE AN EXTERNAL FAN TO AVOID OVERHEATING COMPONENTS !
When you remove the oscilloscope cover and main shield, use an external fan to provide continuous air
flow over the heat sinks. Air flow over the heat sinks is reduced when the cover and main shield are
removed, which leads to higher than normal operating temperatures. Have the fan blow air across the
system board where the heat sinks are located. Otherwise, damage to the components can occur.
WARNING
HAZARDOUS VOLTAGES EXIST — HIGH VOLTAGE IS PRESENT ON DSO6000L SERIES POWER SUPPLY
HEAT SINKS !
The power supply heat sinks of the 6000L Series oscilloscopes are at a high potential. This presents an
electric shock hazard. Protect yourself from electric shock by keeping this area covered or by not coming
in contact with the heat sinks when the power cord is attached to the oscilloscope!
CAUTION
Use only the power cord that came with the oscilloscope
The power cord provided is matched to the country of origin of the order.
