Video Generator with NI Switch modules?

[AVer]

Can anyone out there tell me if it is possible to use any of NI switch modules to switch a composite video signal from the Video Generator board or any other composite or S-video source?"

Dear Sir,

Thank you for using the NI Developer Zone.

The video generator board when generating video signals uses a update rate of 20 MHz to generate the video signal. Because of that probably the video signal will have a sinal bandwidth much lower than 20 MHz.

The SCXI-1127 and SCXI-1129 switch can handle signals with bandwidth of 10 MHz or lower. If the signal that is being generated by the video generator has a frequency bandwidth bellow 10 Mhz there will be very little or no loss of integrity when passing through the relays.
