28.5.2 Instrument Identification Assignment

Another example application of the CBG module is utilizing the 10 µA ISRC output channels to identify and assign an ID for multiple power supplies in a rack-mounted configuration. Typically, rack mounted power supplies use resistors mounted on a backplane to assign IDs to each power supply in the rack. The 10 µA ISRC pins feed these resistors to generate a voltage that is read by the ADC. The ADC value is translated via software into an identifier for each back plane slot.
