The voltage before the spark occurred is related to the spark length, which is also the spark gap width. The oscilloscope photo below shows this changing voltage. This method is good for a rough ...

Both oscilloscope channels are protected for overvoltage ... The FPGA samples inputs at 100 MHz. The output voltage can be set, but inputs are 5 V tolerant. According to the developer, you can ...

To determine peak voltage from an oscilloscope trace, the maximum vertical deviation of the trace from the centre line is measured from the screen. This number of divisions is multiplied by the Y ...
