The mould is small white, ask you a great god, and the amplifying circuit as shown in the figure below, how do I measure the output impedance?
Please everyone a great god grant instruction
(Ps: the input of 0-3.3 V square wave pulse, pulse width 500 ns, pulse interval of 10 ms; Light output is high voltage narrow pulse - 400 - v)

CodePudding user response:

Output impedance=open circuit voltage/short circuit current

CodePudding user response:

Amplifier circuit is this?
