I am a German student. My task is to conduct a characterization of a photodiode (KPEIMC-UDCOM by Kyosemi.) The photodiode will be illuminated by 850-1550 nm laser diodes. It would be good (but not absolutely necessary) if I could do frequency measurements up to 20 MHz.
I'd like to measure the I-V curve, spectral sensitivity, rise/fall time, signal-to-noise ratio etc.
To get a measurable output, I'd like to use a transimpedance amplifier. But that is not what this question is about. My problem is more about the measurement of the voltage and the processing of the data.
I'm not sure whether to use just an oscilloscope, a microcontroller (Arduino?) or something else to get the data and get them plotted.
As I have not much of a background in this topic, it would be nice if you could share some insight on how you would acquire the data for the characteristics I am supposed to investigate.
