The response characteristics of a two‐stage CuSO4solution ‘‘tube’’ resistive divider placed in another CuSO4solution ‘‘tube’’ in a concentric cylindrical configuration for measuring high‐voltage nanosecond pulses have been studied. The test results showed that it was capable of maintaining pulse rise time less than 10 ns, and the hold‐off voltage for pulses with rise times less than 10 ns was 600 kV.
