Chapter 4: Troubleshooting

Power Supply Troubleshooting

The second set of LEDs is located to the left of the first set and slightly lower, below

the J12002 connector (see Figure 4- 6).

Figure 4-6 Second set of LEDs

The following table shows each LED in this second set, the type of fault it indicates,

and what to do if that LED indicator is illuminated. When identifying which acquisition

assembly to replace, remember that the acquisition assembly nearest the bottom of the

oscilloscope is for channel 1. The one above it is for channel 2. The next higher is for

channel 3, and the top acquisition assembly is for channel 4.
