2. Troubleshooting
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 Ω 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.
To Check the USB
Procedure
Connect USB cable between controller PC and USB Interface port (USBTMC) on the rear
panel of E5061B. Turn the controller PC on. If the E5061B cannot detect controller PC, the
problem seems in the CPU module. Agilent I/O Library should be installed on PC.
