Agilent Technologies 1690, 1680 manual To test the logic analyzer probe cables

Chapter 5: Troubleshooting

General Troubleshooting

LED #1 (closest to the red LED) - the on-board processor is properly initialized and running, attempting to load the IEEE 1394 link layer configuration

LED #2 - the IEEE 1394 link layer is loaded and configured

LED #3 - the IEEE 1394 is loaded, properly configured, and is running

A blinking green LED signifies a failure of one of the above steps. In this case, the acquisition board must be replaced.

When the IEEE 1394 port on the acquisition board is configured and initialized, the agLogicSvc service running on the Windows XP Professional operating system senses the acquisition board. The agLogicSvc service then loads configuration code into the interface FPGA on the acquisition board. When the FPGA is configured, the red LED is turned off. The acquisition board is then properly configured and initialized both to communicate with the system processor and to acquire data.

To test the logic analyzer probe cables

This test allows you to functionally verify the probe cable and probe tip assembly of any of the logic analyzer pods. Only one probe cable can be tested at a time. Repeat this test for each probe cable to be tested.
