7.14 Command GA – Master Gain Level
This function is a global gain adjustment for all channels. There are two ways to adjust gain: one is
“Master Tracking” and the other is “Individual”. Command GM selects a required mode. The gain
setting is done in the analog domain where 1LSB equals 0.01dB.
Master Tracking
Settings:
Master (G): 0 to 802
Individual
Settings:
G: -402 to 1404
Associated functions:
Commands GAR, GAB, GAIR - Gain level red, blue, and NIR.
7.15 Commands GAR, GAB and GAIR – Gain Level Red, Blue and NIR.
In conjunction with the Command GA, this function allows the individual setting of gain for
all channels, or it can be used for fine adjustment after one push white balance is executed.
It is important to note that increasing the gain will lead to an increased noise level and
reduced S/N-Ratio.
Master Tracking
Settings:
-402 to 602(-4dB to +6dB)
Individual
Settings:
-402 to 1404 (-4dB to +14dB)
Associated function:
Command GA – Master gain level
Applicable modes:
All modes
Note: Setting data is stored in camera memory for use at next start up
7.16 Command GM - Gain Mode
Selects gain mode.
Settings:
0=Master Tracking (Factory default)
1=Individual
7.17 Command HPFC – Aperture Control
This command enables Aperture Correction to enhance the edge of the picture. The level is pre-set
in the factory.
Settings:
0= OFF, 1= ON
7.18 Command LR - Line Rate (Scan Rate)
This function is used only when there is not an external trigger pulse (e.g. from an encoder) available.
It allows the user to program the line rate, in order to match the speed of the object being scanned.
In the No-shutter mode, the exposure time is directly proportional to the line rate (T
exp
= 1/line
rate)
Settings:
Full resolution/Binning
4602 to 1201920, in 11.9 ns increments
Sub-sampling/Windowing
2554 to 597376 in 19 ns increments
