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...

Mnemonic DATEN
Description Data Enable Low Input. This port controls the 8-bit parallel data latch and shift register. A Logic 0-to-1 transition transfers the latched data to the attenuator core (updates the gain) and simultaneously inhibits serial data transfer into the register. A 1-to-0 transition inhibits the data latch (holds the previous gain state) and simultaneously enables the register for serial data load. Serial Data Input. This digital input allows for an 8-bit serial (gain) word to be loaded into the internal register with the MSB (Most Significant Bit) first. Clock Input. The clock port controls the serial attenuator data transfer rate to the 8-bit masterslave register. A Logic 0-to-1 transition latches the data bit and a 1-to-0 transfers the data bit to the slave. This requires the input serial data word to be valid at or before this clock transition. Common External Ground Reference.

Common Positive External Supply Voltage. A 0.1 F capacitor must decouple each pin. Logic �0� powers down the part. Logic �1� powers up the part. Low Power Sleep Mode. In the Sleep mode, the AD8323�s supply current is reduced to 4 mA. A Logic �0� powers down the part (High Z OUT State) and a Logic �1� powers up the part. Negative Output Signal. Positive Output Signal. Internal Bypass. This pin must be externally ac-coupled (0.1 F cap). Noninverting Input. DC-biased to approximately V CC /2. For single-ended inverting operation, use a 0.1 F decoupling capacitor and a 39.2 resistor between V and ground. IN+ Inverting Input. DC-biased to approximately V CC /2. Should be ac-coupled with a 0.1 F capacitor.
