Hello, I want to set the quantization step size as following:
LL 0.000030517 (1/2^15)
1HL, 1LH, 1HH 0.000030517
2HL, 2LH, 2HH 0.000015259
...
What the QFACT and STEPSIZES should be? Is it work as IEEE 754? Thank you!

Hello,
We have a utility to help you get the step sizes and visual weighting-- it's not intuitive from the way the hardware/firmware was designed. Tool and documentation attached.
Also realize that these controls have only very subtle impacts on the image, it won't be very obvious.

Thank you very much, Daved!
