我在通过 python 与 Siglent SDG1032 函数生成器通信时遇到了很多麻烦。

这是我使用的代码：

import pyvisa as visa

resources = visa.ResourceManager('@py')
print(resources.list_resources())
probe = resources.open_resource("USB0::62700::4355::SDG1XCBD4R4332::0::INSTR")
print(probe.ask("*IDN?"))

但我得到一个错误代码，它是：

usb.core.USBError: [Errno None] b'libusb0-dll:err [set_configuration] could not set config 1: win error: Falscher Parameter.\r\n'

“Falscher Parameter”是德语错误参数；）

任何人都可以帮忙吗？

提前致谢！

编辑：也许您想查看整个错误代码
