10 MHz Clock Source Checking

There is a TXCO generating a 10 MHz 3.3 V LVCOMS clock source to the
entire channel board. Please check it referring to the marked point on the
channel board drawing.

FPGA Checking

To check if the FPGA is working properly, please observe the test point marked
with FPGA_LED on the channel board drawing. The LED light blinks at a 2 Hz
rate in normal operation. If it does not light cannot be lighted or blinks at an
incorrect frequency, then the FPGA may be fault.
