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 switching between 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 A/D converters. The filters used on
Matrox Meteor-II /Multi-Channel are 4th order Butterworth filters 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.
You can change the gain value using the MIL-Lite
MdigControl()
command. The
supported gain factors are as follows:
Max
Number of pixels / line (including sync and blanking)
4096*
Number of lines / frame (including sync and blanking)
4096*
Sampling rate (with external clock input, or in line-locking mode)
