LQ-050CL277.12 Command EI – Interlocked R, G, B & NIR ExposureWhen this function enabled (interlocked), exposure time for all four channels is selectedby setting the green channel and the red, blue and NIR channels will track.To obtain white balance, adjust red and blue channels, PER and PEB. It is thereafterpossible to adjust overall exposure time by using the command PEG. The red and bluechannels will track the green channel proportionally, thus maintaining white balancesettings.Settings: 0= OFF (independent R, G,B and NIR settings)1= R, B and NIR channel interlocked with GSetting range: 50ns to {Line rate ― 52clk(1.3μs)} (Individual R,G,B & NIR) in25ns(1 clock) stepAssociated functions: Commands PER, PEG, PEB and PEIR – Programmable ExposureApplicable modes: Shutter-Select mode only (Internal and external)Note: The LQ-050CL has a priority for the line rate setting. If the exposure is use aroundthe longest exposure speed which is nearly equal to the trigger cycle, please note thefollowings.1. Shutter select mode in the internal triggerThe maximum shutter speed is the setting line rate minus 52clk(1.3μs).2. Shutter select mode in the external triggerThe maximum shutter speed is the provided trigger cycle minus 60 clocks (1.5μs) .7.13 Command GA – Master Gain LevelThis function is a global gain adjustment for all channels. There are two ways to adjustgain, one is “Master Tracking” and the other is “Individual”. Command GM selectsa required mode. The gain setting is done in the analog domain where 1LSBequals 0.03dB.Master Mode: Master(G): -123 to 429(-3dB to +12dB)Individual Mode: G: -363 to 660 (-9dB to +18dB)Associated functions: Commands GAR, GAB, GAIR - Gain level red, blue, and NIR.Note: The adjustment range is available under 7800K light. If light with a colortemperature other than 7800K is used, the adjustable range might be limited.7.14 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 forall 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 andreduced S/N-Ratio. 1LSB equals 0.03dB.Master Mode: -231 to 231 (-6dB to +6dB)Individual Mode: -363 to 660 (-9dB to +18dB)Associated function: Command GA – Master gain levelApplicable modes: All modesNote Setting data is stored in camera memory for use at next start up The adjustment range is available under 7800K light. If light with a colortemperature other than 7800K is used, the adjustable range might be limited.
