Performance

The video timing parameters (including those for progressive
scan) supported by the Matrox Meteor-II /Multi-Channel board

are as follows:

Note that the maximum number of pixels per line that MIL
supports is:

Input channels

The Matrox Meteor-II /Multi-Channel has six independent
analog channels. These channels can support input from two
RGB or six monochrome cameras where the channels can be
selected with the MIL-Lite MdigChannel() command.

Low-pass filter

The input low-pass filtering stage is used to limit high
frequency noise and aliasing effects at the input of the triple
A/D converter. The filter used on Matrox Meteor-II
/Multi-Channel is a 4th order Butterworth filter with a cutoff
frequency of 10 MHz.

Gain

Matrox Meteor-II /Multi-Channel has adjustable gains. This
allows you to optimize the video input signal range.
