channel or board. Possible errors include the
following:
■
The board is overheated
■
The power supply is not at the proper
voltage
■
A clocking error occurred (PLL fell out
of lock or PXIeClk100 was not present
when using the external timebase)
■
An external overvoltage or overcurrent
was detected
[1]
■
An overload was detected
■
A streaming underflow was detected on
