9.2 Gain control
In the GO-5000-PGE, the gain control uses Analog Base Gain and Digital Gain.
Analog Base Gain can be set at 0dB, +6dB or +12dB for both GO-5000M-PGE and GO-5000C-PGE. In the
GO-5000C-PGE, R, G and B channels can be adjusted individually or simultaneously.
The digital gain is used for the master gain setting.
For setting the gain,
1. Set analog gain (Select from 0dB, +6dB and +12dB)
2. Set digital gain
The master gain (DigitalAll) for both monochrome and color can be set x1 (0dB) to x16
(+24dB) against the analog base gain. The resolution for gain setting is x0.01/step which is
0.05dB to 0.08dB, depending on the setting value.
3. In the GO-5000C-PGE, blue and red gain can be set from x0.447 to x
4 against the master gain
setting and its resolution is x0.01/step.
4. In the GO-5000C-PGE, analog gain can be applied to R, G and B channel respectively in order
to cover a wider range of color temperatures.
The master gain control uses Digital Gain Control. All digital gain can be set by x0.01/step. If the
digital gain is set too high, gaps in the Histogram may occur.
