@PeDre: that is very kind, thank you, but i am working on Linux.
@2N3055: thank you. But it seems that LeCroy is depending on Windows/Basic and so on.
I didnt manage to get SCPI fully to work on LeCroy (nor LXI). While i can attach the Device and, for example, set an SCPI command, for example *IDN?, it seems that the Lecroy is not fully supporting SCPI because the other commands are not working and the (very) old Error Messages ( at least 5 years old) is given by th LeCroy: WARNING : CURRENT REMOTE CONTROL INTERFACE IS TCPI
This message is given regardless if connected with visa or vxi.
My opinion is that I have no problems connecting all sorts of devices, Rhode & Schwarz, Keysight, Socket, GBIP, etc., etc. because they are supporting simple TCPIP socket connections
