Input PSI Table
The following table contains a list of program-specific information messages that are
extracted from the APEX1000 inputs. All messages extracted from APEX1000 inputs
that are being used by the APEX1000 are displayed (PATs, PMTs, and PITs):

Definition
Level at which the GigE frame buffer will be reset (in milliseconds). This
value is based on the Maximum Input Data Rate. The APEX1000 calculates
this level using the input data rate and the total number of GigE frame
buffers. This limit is calculated to force a reset to prevent a GigE frame buffer
overflow.
Note: A reset of the GigE frame buffers will result in a momentary glitch;
however, this is preferred, instead of a buffer overflow that will cause
glitching until the level drops or the buffer is reset.
In normal operation, it is expected that this level will never be reached or
exceeded. Exceeding this level indicates that the APEX1000 is either
incorrectly configured (incorrect input data rate) and/or the input to the
APEX1000 exceeds the maximum recommended data rate.
Major – Current Buffer Level Fullness has exceeded the Frame Buffer Alarm
Threshold.
Critical – Current Buffer Level has exceeded the Buffer Overflow Level.
