I want to measure current pulses from a photodiode that are 5 ns wide and occur every 13Hz .
The current pulses can range from microamps to nanoamps.
I need an amplifier that should be easy to connect , budget around 100-300$ and also detect these short pulses,
I selected ADN2822, after some discussions.
My question is-
a. if the bandwidth is in GHz , will that be good enough to measure a nanosecond pulse.
b. Any other/better suggestions?
