Table 5. Access LED
Color
Indications
Off
The module is not yet functional or the module has detected a problem with a power
rail.
Amber The module is being accessed.
Green The module is ready to be programmed.
Table 6. Active LED
Color
Indications
Off
Module is not armed, triggered, or acquiring a waveform.
Amber The module is armed and waiting for a Reference (Stop) Trigger.
Green The module has received a Reference (Stop) Trigger. Also indicates that the module
is acquiring a waveform.
Red
The module has detected an error. The LED remains red until the error condition is
removed. The following scenarios are examples of potential errors:
•
Detected an unlocked condition on a previously locked PLL. A PLL that is
unlocked while in reset does not show an error.
•
Unable to detect the external sample clock.
•
Detected an overheating or overpowering error.
Note
Certain driver interactions may cause the Active LED to flash red.
An error condition does not exist unless the Active LED remains red.
