使用Agilent 33500B波形发生器返回本地

我有一个Agilent 33500B波形发生器，我通过USB使用VISA连接远程通信（pyvisa发送SCPI命令）。
当我从33500B断开连接时，我想手动或用软件将其恢复到本地模式。
我无法以任何方式工作：1。33500B说“远程仪器。按LOCAL”。
但是，Local按钮是一个标有“System”的键，下面写着“Local”。
我应该按一个换档键吗？
如果是这样，这是什么？
如果没有，为什么按“本地”什么都不做？
2.查看程序员手册，它说将33500B返回到本地，“从远程接口执行IEEE-488 GTL（Go To Local）命令”。
但是，那个命令是什么？
我尝试过像“* GTL”这样的SCPI命令的变体，但没有任何效果。
到目前为止，我唯一的办法是关闭整个系统并重新启动33500B。
但从长远来看，这是一种不可持续的做法。
谢谢。

  I have an Agilent 33500B Waveform Generator that I am remotely communicating with using a VISA connection over USB using Python (pyvisa to send SCPI commands). When I disconnect from the 33500B, I would like to return it to local mode either manually or in software. I cannot get it to work either way:

1. The 33500B says "Instrument in Remote. Press LOCAL." But, the Local button is a key labeled "System" with "Local" written underneath. Is there a shift key I'm supposed to press? If so, which is it? If not, why does pressing "Local" do nothing?

2. Looking at the programmer's manual, it says to return the 33500B to local, "execute the IEEE-488 GTL (Go To Local) command from the remote interface". But, what is that command? I've tried variations on SCPI commands like "*GTL", but nothing is working.

So far, my only recourse has been to shut down my entire system and restart the 33500B. But this is an unsustainable practice in the long run.

Thanks.
