About the Matrix Test Signal
The Matrix test signal is supplied on the accessory signal source disks included with this product. There is a Matrix signal for
Options SD and HD and a Matrix signal for Option VGA. The Matrix signal incorporates all analog video signal requirements
into different line numbers within one test pattern
fi eld. Using a single test pattern eliminates the need to change test
signals when doing different measurements. All you need to do is specify line numbers on which measurements are taken.
Use the setup
fi le (.vmset) that matches the format of the Matrix test signal you are using; this provides appropriate line
numbers as default settings for each measurement type. See the VM Series Video Measurement System User Manual for
a full description of the fi les on the signal source disks.
