[SI-LIST] Re: The Ground of VNA

Hello, Zhang Kun,

Of course the grounds on the outputs on any instrument would be connected.
If you do not have a ground plane in your DUT, you can only accurately
measure it if you have some sort of virtual ground.


Thanks,

connected. However, I do not know the detail.
