You can change the gain value using the MIL-Lite MdigControl() command. The supported gain factors are as follows:

Input video signal	Total input video	Required	MIL
amplitude	signal amplitude	gain
(excluding sync)	(including sync)	setting
0.0 V up to 0.5 V	0.0 - 0.7 Vpp	4	M_GAIN3
0.5 V up to 0.7 V	0.7 - 1.0 Vpp	2.8 (default)	M_GAIN2
0.7 V up to 1.0 V	1.0 - 1.4 Vpp	2	M_GAIN1
1.0 V up to 1.5 V	1.4 - 2.1 Vpp	1.3	M_GAIN0
1.5 V up to 2.0 V	2.1 - 2.9 Vpp	1	M_GAIN4

Triple A/D converter

A triple A/D converter with external reference generation and sync slicing is used for component RGB digitization. The converter can be operated at up to 30 MSPS.

In addition, the converter’s black and white reference levels can be adjusted individually. The black and white reference levels can be adjusted between 0.6 V to 1.6 V and 1.6 V to 2.6 V respectively, in increments of 10.23 mV (98 distinct adjustments).

Use the MIL-Lite MdigReference() command to set the black and white reference levels.

PSG

The Programmable Synchronization Generator (PSG) is responsible for managing all timing and synchronization signals.

Phase-locked loop

The high-performance, low-jitter phase-locked loop (PLL) uses frequency synthesis techniques to generate the clock signal, when necessary.

The PLL can use the following sources as a reference:
