1 Factory Calibration

Set the beta IP for easy access.

beta=192.168.1.101

1.1 Step 1: Check range of the input signal

Set gain with:

ssh root@beta "./set_gain 1

Take an overexposed image and check the levels:

ssh root@beta "./cmv_snap3 -2 -b -r -e 100ms" > snap.raw12
raw2dng snap.raw12 --totally-raw
octave
   octave:1> a = read_raw('snap.DNG')
   octave:2> prctile(a(:), [0.1 1 50 99 99.9])

Lower numbers should be around 50...300 (certainly not zero). Higher numbers should be around 4000, but not 4095.

Repeat for gains 2, 3, 4.
