EUT Description / Note:
The EUT, Specialized Reprogrammable Hardware,A-U250-P64G &A-U250-
A64G uses a 156.2MHz oscillator and the PCIe 100Mhz clocks. TheA-U250-
A64G was tested as the worst case for emission testing. See the EUT Technical
Description and Block Diagram for further details.

EUT Support Program
The EUT and all support equipment were exercised in all operating modes for
determination of worse case emission under typical operations.The system is
continuously running with the XBB Demo program as observed on the host PC
monitor. Data reported for conducted and radiated emissions reflects worse
case conditions.
EUT Modifications for Compliance
There were no modifications performed on the EUT. The test results state the
emission and immunity level of the EUT in the condition as it was received
July 13, 2018.
