(Questions) Designing a cheap high speed ADC for analyzing inductors

[Fireflaker]

Hi everyone
I am working on designing a high speed ADC frontend to measure the rising edge slope of the inductor current. Just wondering if there can be a way to do it without needing high speed FPGA.

You can just read out an oscilloscope capture, or a DAQ cature.

Why would you design your own device for what is I assume an experiment? Your requirements aren't special and the one off nature doesn't really justify all the effort.
