Gain control
In the GO-5000-USB, 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-USB and GO-5000C-USB.
digital gain is used for the master gain setting.
For setting the gain,
1. Set analog base 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-USB, blue and red digital gain can be set from x0.45 to x
Master gain setting and its resolution is x0.01/step.
4. In the GO-5000C-USB, analog base gain can be applied to R, G and B channel respectively in
order to cover a wider range of color temperatures.
Note1: If the gain up function is used, it is recommended to use the analog base gain as the
master gain setting. For instance, if +12dB gain up is required, the analog base gain
is set at +12dB and no digital gain is added. This is because the signal-to-noise
performance is better with analog gain applied. However, the AGC function works
only with digital gain.
Additionally, the analog base gain is effective in order to minimize any breaks in
the histogram at higher gain settings. Please note that the analog base gain has
less accuracy due to its variability.
The master gain control uses Digital Gain. All digital gain can be set by x0.01/step. If the digital
gain is set too high, breaks (missing counts) in the histogram may occur.
