Step 2. Turn the instrument on.
Step 3. Move the mouse and verify that the mouse pointer move smoothly. If it
doesn’t move smoothly, check first whether a foreign substance (dust, lint,
etc.) is in the track ball hole of the mouse or not.
Step 4. Verify that the mouse buttons work normally. If any button doesn't work or
the mouse pointer doesn't move, a failure in the mouse or the A50 CPU
Module is suspected.
To Check the Video output
Procedure
Step 1. Connect an external VGA color monitor to the Video output port on the
E5061B rear panel.
Step 2. Turn the external monitor on.
Step 3. Verify that the monitor screen view is the same as the display on the LCD. If
the monitor screen view is abnormal, a failure seems in the CPU module.
To Check the External Trigger Input
Procedure
Step 1. Press key to initialize the E5061B.
Step 2. Press key.
Step 3. Click Trigger Source and, then, External in the menu bar to set the trigger
mode to "External".
Step 4. Connect a BNC Short or 50 termination to the Ext Trig connector on the
rear panel and disconnect it. Thereby a measurement trigger should be
generated and a measurement result (trace) should be refreshed.
Step 5. If no trigger occurs, a failure in the DSP board is suspected.
To Check the GPIB
Procedure
Perform the E5061B performance test program. If the controller cannot detect
the E5061B, the problem seems in the CPU module.
