使用Lxi TCP端口5025设置学习字符串

我有一个DSO3034A，我想用一个简单的tcp套接字和Scpi-raw远程控制它。
我实际上可以毫无问题地执行scpi命令，我甚至可以使用“：SYST：SET？”来请求学习字符串。
但问题是我似乎无法将其设置回来。
在文档中提到我应该用“：SYST：SET”将其发回，然后在数据之后。
我尝试过的一个例子：SYST：SET＃800083042 expandMode 0，“ground”wfmAntialiasing ....更多数据......看起来很简单，但直到现在我都没有成功。
有人可以帮我这个，说我做错了什么？
我使用TcpClient和c＃来处理套接字通信。
谢谢，彼得

  I have a DSO3034A an I want to remote control it using a simple tcp socket and Scpi-raw.

I can actually do execute scpi commands without a problem, I can even requests the learn string using ":SYST:SET?".

But the problem is I don't seem to be able to set it back. In the documentation it is mentioned that I should send it back with ":SYST:SET " and after that following the data.

One of the examples I tried :

:SYST:SET  #800083042    expandMode 0,"ground"   wfmAntialiasing
....  
more data
....


It seemed straight forward but I have no success with it until now.

Can someone help me with this, say me what I do wrong ?

I use TcpClient with c# to handle the socket communication.

Thank,
Peter
