按照你的设置手册,安装软件和usb驱动,好像usb驱动有问题,“12、到"communicate with adapter" 下并且点击 "check vna interface". 你会得到一个
"n2pk vna interface found" 的消息, 并且 "read vna interface" 和 "write vna interface"
按钮会变得可用。”总是错误,显示“attempt to read expected configuration string from
vna usb interface failedattempt to read expected configuration string from
vna usb interface failed”
如何处理,检查硬件管理器,pc上装了cypress ez-usb fx2 (68613)-- eeprom missing.
是正确的吗?
试过删除myvna并重新安装还是一样。
