Solving General Problems with the Oscilloscope
This section describes how to solve general problems that you may encounter
while using the Keysight 6000L Series Oscilloscopes to make measurements.
After troubleshooting the oscilloscope, if you need to replace parts, refer to the
“Replaceable Parts” chapter.
On 6000L Series oscilloscopes, connect an XGA display to the display port on the

oscilloscope. If you do not have the user’s guide, you can download it from
