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.
