The specifications of a differential voltage probe is given in the attached image. I'm confused with some of the specifications. Kindly advise the following:
[1] What does "Common Mode Voltage DC + pk AC: 6500V" mean?
I'm interested to learn how can we achieve such design (e.g. 6500V, DC-50MHz). I found several difference amplifiers, e.g. INA117 and AD629, but their bandwidths are only 200kHz and 500kHz, respectively, and they are designed to use in application with the presence of common-mode signals up to ±270VDC only.
