When you connect the scope, you should se a clear "eye pattern" signal, like the one above.
When you increase laser power, the amplitude (height) of the pattern will increase. Do not adjust too high, or the pattern will "clip" at the top and bottom.
You will have to test with several different discs/media as all media have different reflectivity. Therefore, if you calibrate the laser so it will be just below clipping with cd-r media, it might "clip" when using originals.
We recommend you take readings from a brand new PS2 to get reference levels. Normal values are 800mV peak to peak with DVD media and 640mV peak to peak with CD media.
