One problem that comes up again and again in doing measurements is that we need the apparatus to be quieter than the thing we're measuring, ideally by at least a factor of two. Besides quiet, it should be wideband, have an accurately known gain that's flat with frequency, have a clean step response, and generally do its job while keeping itself out of the way. There's a wealth of detail in our app note AN-1 on photoreceiver testing.
