Hi, FvM,
The rising is about 1ns, so it's truly that the signal can reach 3G.
In many electric power standard, for such sensor, the detected freq band is 300M-1.5G. The sensor uses antenna to detect the discharge inside the high-voltage box. So the impedance for my sensor is 50 ohms.
But they can detect 1pC min, that is about 10uV.
Yes, the final design should give PRPS chart and PRPD chart. That is some phase, freq, amplitude, etc., chart.
I guess I need to do sth like a spectrum analysis, right?
Best,
Tony Liu

PS:
The discharge pulse emerge TEM wave, which osc in the power cable, from one insulated point to the other. Then its duration maybe more than 10uS.
And the sensor using antenna to detect it from some windows in the power cable.
That is two systems.
Best,
