The Model 3750 Signal Distribution Unit serves as a buffer between a source of time or other digital or analog signals and a user, providing both signal amplification and isolation. The unit is available in either 1.75, 3.5, 5.25 or 7 inch high rack mount chassis. In the 3.5, 5.25 and 7 inch high versions all modules are front loading and available behind a hinged front panel door. In the 1.75 inch high chassis the modules are available beneath a hinged top cover. · · · · · · time@datachroninc.comwww.datachroninc.com Fax: (714) 491-8213(714) 491-8500 Anaheim, CA 928051333 South Lewis Street product description. The list is expanded as new modules are developed. be drawn from an extensive library of available cards. A list of available cards is provided at the end of this its 3.5 and 5.25 inch high form and up to 30 buffer modules in its 7 inch high configuration. These modules can .75 inch high configuration; up to 15 buffer modules inThe Model 3750 houses up to 4 buffer modules in its 1 SIGNAL DISTRIBUTION UNIT MODEL 3750 four (4), fifteen (15) or thirty (30) of the cards listed inOne copy of an operation and maintenance manual is furnished with column two depending upon the unit’s chassis height. The standard BNC connectors. In this configuration the three input signals are bussed to each of the card connectors. Most of the card types accept three inputs and include plug jumpers to select which of the inputs will be buffered and output. This approach permits the user to easily Distribution Unit. Separate specification sheets are available for each Other card types contain two or more buffers. When these cards are For high frequency applications (1MHz and above), all internal wiring is coaxial. For low frequency applications, twisted pairs are The Model 3750 is equipped with an integral power supply which operates from an AC input of either 105-125 or 210-250 volts AC, 47-440Hz, 1 amp maximum. Unregulated power is bussed to each card where power regulation is performed. This eliminates power voltage variation in distribution and also evenly distributes heat The Model 3750 is housed in a rack mountable chassis with The chassis is black anodized. The front panel is black anodized or painted black with white lettering. Other colors are available.
