I always find this confusing. for the 1600, RN is listed as 1.2e @30dB gain.
I assume this doesn't mean 'Gain setting 30' because according to the graphs in the manual, the gain units are in units of 0.1dB. So dividing by 10 can I assume that 300 Gain is 30dB and the magical point at which read noise is referenced to 1.2e?
As mentioned, it varies by gain, but I'm not sure how to calculate it for *other gains. I'd rather calculate it exactly rather than read values off those hokey little graphs but I don't know how.
