Glitch Voltage config for having a 3,3 high voltage through SMA connector

Hi everyone,

I’m doing voltage glitching but when I have watch out my glitch waveform with an external scope, I have seen my glitch signal high voltage is 2,4 V and my glitch signal low voltage is almost 1 V.

It seems I have done a mistake on my UFO CW308 board.

Actually, I use CW-Lite and CW308, my CW308 is supplied thanks to my CW-Lite.

Could you explain me the exact configurations for having a 3,3 V high voltage glitch ?

Thank you and have a nice day !
