Keysight offers several options for the N6760 DC power module series.

Please note, options are model specific.  For example, option 2UA for an N6761A and N6762A would be N6761A-2UA and N6762A-2UA.

All options for the N6760 series are grouped together and can be navigated to from this page. 

This option enables a 200 microampere measurement range and also includes the option 761 relay capability.

Please note, this is only available for the N6761A and N6762A.

With option 760, Output Disconnect/Polarity Reversal Relays, mechanical relays switch the leads on both the plus and the minus side of the power supply, including the sense leads, resulting in a voltage polarity reversal at the DUT. In addition to polarity reversal, option 760 provides the same output disconnect function as option 761. 

With option 761, Output Disconnect Relays, an emergency condition or turning the DC output off causes mechanical relays disconnect both the plus and minus side of the power supply, including the sense leads.
