1 Troubleshooting
To Check the GPIB
Procedure
Perform the Keysight E4991B Performance Test program. If the
controller cannot detect the Keysight E4991B, the problem seems
to be in the A80 CPU module.
To Check the USB
Procedure
Connect a USB cable between controller PC and USB Interface
port (USBTMC) on the rear panel of the Keysight E4991B. Turn the
controller PC on. If the Keysight E4991B cannot detect the
controller PC, the problems seems to be in the CPU module.
Keysight I/O Library should be installed on the PC.
