• The unity gain is the gain position that the system gain is 1e/ADU. At lower gain settings, the system gain will exceed 1e/ADU and this will cause the sample noise. The QHY168C unity gain setting is 10. For DSO capture, there are two capture methods. One is the traditional long exposure DSO capture, Another is the Lucky imaging method with a ...

  • You're right, it makes sense from ADC point of view, so for gain setting of 10 we have 0.08125*16 = 1.3 e-/ADU, and as you wrote unity gain will be little above 10. When we plot this real ADC gain versus camera gain setting we got this log plot: So the unity gain seems to happen at gain setting between 12 and 13. Cheers. Lucas

    • Unity gain is achieved by applying 100% feedback to a high gain amplifier. There will be phase shift between input and output and oscillation occurs when phase shift equals or exceeds 180 degree at any frequency where the open loop gain is greater than unity (actually always in practice at a range of frequencies.)

    • For me, the best spot is unity gain where 1 electron equated to 1 ADU, so there are no quantization artefacts and you get access to the full well depth. On this camera (and all ZWO cameras I think), this is at a gain of 120. As to the offset, at unity gain (and this works on the ASI183 and the ASI294), an offset of 10 works just fine.

    The idea of “unity gain” is essentially that when passing audio through a piece of gear, if the output level is the same as when the device is not in the signal path, “unity gain” has been achieved — input equals output, level-wise. Basically, you put one volt in, you get one volt out, which is said to equal a gain of one or “unity.” Gain 139 => Offset 21 (Unity) Gain 200 => Offset 50 Gain 300 => Offset 65 For the most part, the optimal gain settings for this camera are 75, 139, and 200, which give you: * Unity gain (139) which is sort of your "balanced" setting and is a good all rounder for the average user looking to keep things simple and easy.FullWell >32ke- QE 78% Readout Noise [email protected] gain [email protected] gain System Gain TBD Unity Gain TBD Frame Rate (on 8bit) 138FPS @ 1936*1216 [email protected]*600 [email protected]*300 ROI Support Yes.

    As far as your characterization of measures I think it preferable to express gain in terms referencing back to the resolution of the ADC for this camera which is 12 bits. Hence the gain at the zero setting would be 0.26*16 or ~4 e-/ADU. So unity gain would be somewhere above a setting of 10.
