Chapter 5: Troubleshooting
Primary Trouble Isolation
78
Use the following procedure to test the front-panel LED (light-emitting diode) indicators.
1 Enable the graphical interface.
2 Select Self Test from the Utilities menu.
3 Select LED from the Self Test drop-down list box, then select Start Test.
The LED test screen appears, which shows a symbolic representation of all front panel LED
indicators. See See Figure 5-4.

LED Test Screen
4 Push the Marker A left and right arrow keys to highlight each LED symbol in the test
screen. Verify that the corresponding LEDs on the front panel are the only ones
illuminated.
5 When you are finished, select Close.
If any of the LEDS do not work, see “To check the LEDs” on page 87.
6 If both tests pass, go to step E.
E
Self Calibration
1 Complete a self Calibration by following the procedures. See “Testing Performance” on
page 37.
2 If the calibration test fails, replace the acquisition assembly. If the calibration test passes,
go to step F.
F
The system is operational. Performance test the oscilloscope. See “Testing
Performance” on page 37.
Test by Rows
You can use the Marker B arrow keys to test LEDs by row; however, in the event that two LED indicators
are shorted together, there is a small chance that the test will not reveal the failure.
