• CPU/FPGA sensor—Digitally reports the die junction temperature of the Xilinx Zynq
SoC.
• Primary System sensor—Digitally reports the temperature on the Xilinx Zynq SoC side
of the circuit card assembly. This value is a conservative approximation of the local
ambient temperature on that side of the circuit card assembly.
• Secondary System sensor—Digitally reports the temperature on the secondary side of the
circuit card assembly. This value is a conservative approximation of the local ambient
temperature on that side of the circuit card assembly.
In addition to being useful for system validation, digitally reported temperatures also provide
feedback about system health and can be used as triggers or set points.
NI recommends that you monitor the digitally reported temperatures on deployed systems,
especially if the temperatures approach the maximum thermal specifications during system
validation testing. Monitoring allows individual systems to identify adverse thermal changes
caused by differences in environmental, operating, or process conditions.

measurements, visit ni.com/info and enter the Info Code sbriosensors.
