The HP 66312A is a single-channel 40W dynamic measurement DC source with GPIB and RS232 connectivity.
It is part of the HP 663xxx series. The same device appears with HP, Agilent and now Keysight branding, following the history of subdivision of the company.
The device uses the same SCPI command set over both the RS232 and GPIB ports. The interface and communications settings to use must be selected from the front panel before remote use.
