Keysight offers multiple options for the N6770 DC power module series.  

Please note, options are model specific.  For example, option 054 for N6773A and N6774A would be N6773A-054 and N6774A-054.

All 054, 760, and 761 options for the N6770 series are grouped and can be navigated from this page. 

Option 054

Option 054 (High-speed Test Extensions) includes an output list and digitized measurement capability. This option is separately orderable for Models N673xB, N674xB, N677xA, and N675xA when installed in N6700 MPS mainframes. All other power modules as well as the N6705 DC Power Analyzer mainframes have an output list and digitized measurement capability built in.

•  Output list: 
•  Maximum number of steps = 512 
•  Maximum dwell time in seconds = 262 
•  Maximum list repetitions = 256 or infinite 
•  Digitized measurement: 
•  Maximum measurement points = 524,288 
•  Maximum sample rate = 97.656 kHz 

Option 760 

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. 

Option 761 

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