ATS9353 User Manual
•
LINK (LED9)
: This LED being ON indicates that a PCIe link has been
negotiated between the board and the motherboard. The exact time at which
this LED turns on is dependent on the motherboard and its BIOS. Typically,
this LED will turn on a few seconds after the FPGA is configured. If the FPGA
LED is on but LINK LED does not turn on, it indicates either: the
motherboard slot is not enabled by the CPU or the BIOS; or there is a
problem in the transceiver power supplies; or one or more of the transceiver
coupling capacitors along the gold-fingers on the secondary side have been
damaged.
•
TRIG (LED10)
: This LED being on indicates that the board has received a
trigger and is capturing post-trigger data. If board is being triggered
repeatedly, this LED will blink or, if the trigger rate is very high, may even
appear as a dimly lit LED
•
MEM (LED11)
: This LED indicates that on-board memory is detected by the
board. When the software driver is loaded at the start of an application, it
forces a full memory test. If the test is completed successfully, this LED is
turned on, otherwise it remains off. If this LED is off, there is a hardware
problem with the ATS9353.
•
BUSY (LED12)
: This LED being on indicates that the board has been armed
for capture. If board is being armed repeatedly, this LED will blink or, if the
re-arm rate is very high, may even appear as a dimly lit LED.
