LED Description
<AI 0..1> AMBER/GREEN (alternating)—The reference
clock source is changing to onboard or
PXIeClk100.
AMBER (solid)—The channel is waiting for a
trigger to start acquiring.
GREEN (solid)—The channel is actively
acquiring a signal.
RED (solid)—An error has been detected on the
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 PXIe_CLK100 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
the channel
■
Internal hardware failed (either due to
soware or hardware failure)
<AO 0..1> AMBER/GREEN (alternating)—The reference
clock source is changing to onboard or
PXIeClk100.
AMBER (solid)—The channel is waiting for a
trigger to start generating.
GREEN (solid)—The channel is actively
generating a signal.
