问题：
Can VM5000 or VM6000 with option SD be used to test a SCART interface?
答案：
Yes, Option SD enables component analog signal analysis to be performed on RGB channels with composite video input on Channel 4 for triggering. Some sync parameters can be measured on the composite signal used for sync, yet for complete H timing analysis, VM700T is still required.
If warning messages are enabled, the message "back porch reference questionable" will appear. This is normal when you are using a signal like the SCART format that does not contain sync on each channel. In this particular case, you can ignore this message and the VM5000/6000 will make measurements.
