I have been put in charge of trying to find out how to control our Agilent Power Supplies with Python Scripts. We have models 6812b and N6705b. I have no idea where to start. So, I thought I would start here. Any advise/help would be greatly appricated.

Hi

The N6705B is pretty straight forward.
Put it on the lan
open a socket, :5025
Send SCPI text strings
Read values back.

I'd show code but I only know Tcl :)

  If anyone else reading this thread has any python examples I would very, very much like to see it/them.

    Here is a python example of opening a socket session (port 5025) and sending the basic *IDN? command.

      Hi
      
      Do you actually need the DLLs to talk tcp over the socket?
      In TCL I just open the socket and send the SCPI text !

        If you are using TCPIP sockets to send commands (port 5025), and your environment can talk to TCPIP sockets (TCL and Python both can), then you don't need any external libraries.
        
        However, if you want to use some other connectivity bus, like USB or GPIB, then you will need VISA which is part of the Agilent IO Libraries Suite. You would also need VISA if you were going to use the VXI-11 or HiSLIP protocol layers on LAN. These protocols give you nice features like Device Clear, Service Requests (SRQ), and GPIB emulation.
        
        If your control tasks are simple, then TCPIP sockets should work just fine.
