VGA Interface Testing with the VM5000

Many devices depend on high performance color displays, including personal computers, video
gaming appliances, and home theaters. Even with digital display interfaces such as DVI, analog
RGB persists due to the large number of analog-only displays and the flexibility and reliability of
the analog interconnect. Frequently a 15-pin RGBHV analog interface is used. Developed originally
for VGA PC graphics cards, this physical interface is capable of very high performance. But
impairments can and do occur because of failures or poor design. Verifying proper RGBHV
interface operation can help ensure that displays work predictably and deliver top-quality results.
