I think this is an implementation issue at GWI, but wondered if anyone had any ideas or previous experience? I suspect this is all due to me not understanding the difference between VISA, VXI, LXI etc., but I have been working happily with PyMeasure in a way that seems to work OK, until I hit this problem.
I have several instruments that all seem to work quite happily, but not this one (GW Instek MFG-2230-M). I think it will only accept VISA connections, so a connection string something like:
“TCPIP :: 172.16.28.144 :: 1026 :: SOCKET”
.. which is rejected by the vxi11 library as a malformed string, and presumably it would need to parse the socket number as well, rather than performing the vxi protocol (or whatever it is) to establish a socket.
If I try a connection string like: “TCPIP :: 172.16.28.144 :: INSTR”, this is accepted by the vx11 library, but I just get a "connection refused" error when I try to send a message.
