UVW-1800 analog component video output low into Decklink Extreme

Question

I have come to realize that my UVW-1800 is feeding into my Decklink Extreme card at 75% of the level it should (based on NTSC bars). I can raise the input level of the Decklink. But I wonder if the ultimate problem is increased noise using this fix. I am about to test the composite output level. I do not have a regular WFM moni so I can't see the level until after I get it in.
Thanks, Chris.

Chris-
You might also look on eBay for a TBC remote. Even using the scopes in the Final Cut capture window will be OK. Analog video is subject to huge variations in levels and chroma. Getting them close to proper at the machine will give you a much more pleasing result than adjusting them after the fact in the digital domain.
The usual order of adjustment for analog machines is to first set the black level, then the white. If you adjust the white much it will affect the blacks, so go back and reset those. Which will affect the whites. so go back to THOSE. Usually about 3 tweaks on each will get both to the proper levels. Then set the chroma amount, and hue (if you are using the composite signal).
Finally on the %75 percent issue. It turns out that in analog video if you add the R,G,and B signals you only get 75%. So if you have full field bars that may be correct. You need SMPTE bars, which have a 100% white box at the bottom of the frame, to correctly set your video level.
