Analog Control
8.2 Gain control
In the SP-5000-CXP2, the gain control uses Analog Base Gain and Digital Gain.
Analog Base Gain can be set at 0dB, +6dB or +12dB.
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
0.01%/step which is 0.05dB to 0.08dB, depending on the setting value.
In the SP-5000C-CXP2, blue and red gain can be set from x0.45 to x
5.62 against
the master gain setting and its resolution is x0.01/step.
3. In the SP-5000C-CXP2, Analog Gain can be applied to R, G and B channel
respectively in order to cover wider range of color temperature.
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
is better on analog gain performance. However, the AGC function works only in
digital gain.
Additionally, the analog base gain is effective in order to minimize gaps in the
histogram at higher gain settings. Please note that the analog base gain has less
accuracy due to its variability.
