This is a good quality scan of the Operation & Maintenance (Service) Manual for the PAL version of this high-band broadcast umatic, BVU-800P
All schematics and lineup procedures appear to be included in this one manual AFAICT.
The file size is just over 113 MB which gives an idea of the quality and number of pages.
All of the schematics, which contain some fairly small print, are easily readable when you zoom into the page.

Good quality, all schematics of few of models. There is also short form of user manual and regulation manual.

Perfect copy of the service manual. you can enlarge every page, and it comes up
with all details.

It´s very very nice manual with all, what i need. Original in good quality. Very fast business. Very much thanks...
CHAPTER 2
3. Calibration When scanning a document of even density, the image signal corresponding to each pixel may be uneven due to the following reasons: * Uneven light intensity of the scanning lamp * Variation in the sensitivity of the light phototransistors * A slight output from the light phototransistors with no light Calibration corrects these variations with the following three steps: Offset Calibration Coarse-gain Calibration Programmable Gain Amplifier (PGA). 1) Offset Calibration Normalize the output data from each pixel at the value of 0 or near 0 by using data aquired with no light. 2) Coarse-Gain Calibration Finds the optimum gain setting to have the output voltage from all pixels within in the adjustment range of Programmable Gain Amplifier. 3) Programmable Gain Amplifier (PGA) Calculates a gain coefficient to make output constant by correcting the output difference among pixels.
4. Filter Processing Changing the resolution and the scaling tends to reduce the image quality. To prevent this, the filter processing needs to be performed according to the resolution. The filter processing includes interpolation processing and averaging.
