All PS SYSMON sensor channels and the internal PL SYSMON channels use a unipolar sampling circuit. The PL SYSMON external sensor channels can use unipolar or bipolar mode, selectable on a per channel basis. Operational details of the sampling circuit are discussed in the UltraScale Architecture System Monitor User Guide (UG580) [Ref 6]. PS SYSMON uses only unipolar mode. PL SYSMON uses unipolar mode on its internal sensor channels, and unipolar or bipolar mode on its external sensor channels.
