E5071C命令转储图像语法错误

嗨，我有问题尝试使用PYVISA（SCPI命令）获取VNA E5071C的转储图像下面是我的代码：import visa rm = visa.ResourceManager（）myvna = rm.open_resource（rm.list_resources（）[0
]）打印myvna.write（mmem：stor：imag“”D：picture.png“”“）我尝试了几个实例，如大写，小写，单引号等。前三个命令有效（我正在使用）
shell一次输入一个命令）我知道我正在与正确的设备通话。我可以将文件从VNA（手动转储图像）传输到主机，但出于某种原因我无法接受
VNA的转储图片。请帮助。感谢编辑：rudy022于2015年10月1日5:07 AM编辑：rudy022于2015年10月1日上午5:13

  Hi,

I'm having issues trying to take a dump image of the VNA E5071C using PYVISA (SCPI commands)

Below is my code:

import visa
rm = visa.ResourceManager()
myvna = rm.open_resource(rm.list_resources()[0])
print myvna.write (mmem:stor:imag ""D:picture.png""")

I tried several instances such as upper case, lower case, single quotes, etc.  The first three commands work (I'm using shell to enter one command at a time) and I know I'm talking to the right device.

I can transfer files from the VNA (a dump image taken manually) to the host computer, but for some reason I can't take the dump image of the VNA.  Please help.

Thanks
