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 flashes at the
rate of 1Hz in normal case, if it cannot be lighted or twinkles at incorrect
frequency, then the FPGA may be at fault.
Connector Checking
Table 5-5 Connectors of the Channel Board
Table 5-5 explains the function of all the connectors on the channel board. It is
important to ensure that all the connections are tight.
