Frequency Distribution Amplifier

Информация

The Model 8140 Frequency Distribution Amplifier receives a standard input frequency and conditions it for distribution to remote points via a coaxial cable distribution network and interface units. The , Model 8140 thus provides a precision frequency reference to up to 25 remote locations, eliminating the need for an expensive precision time-base or reference in the remotely located equipment 10 ,5 -, 1 , or 0.1MHz signals, selectable by pushbuttons on the front panel, are available from the “STANDARD OUTPUT” BNC connector on the front panel. Up to four networks can be connected to BNC connectors on the rear panel, with up to 25 line tap loads distributed among them. The networks are driven by a 10-MHz signal unaffected by the front-panel pushbuttons. Each remote station is fed by a model 8140 T or 8140 TTL Line Tap interface unit. The Line Tap receives both the distributed RF signal and dc power from the coaxial distribution cable. The RF signal is buffered, divided down to the frequency required by the equipment to be driven, filtered, and made available at the BNC output connector. The TTL version is specially designed to drive TTL loads. The Line Tap modules are ordered specifically for the desired output frequency, which may be 10, 5.0, 1.0, 0.5, or 0.1 MHz. If special frequencies, such as 1.544 or 2.048 MHz are required by the customer, the Model 8140 VT VersaTap™ may be used. Contact Customer Service or your Spectracom Sales Representative to discuss these requirements. The standard-configuration Model 8140 requires an input frequency of 10.0 MHz, but one of three options may be installed to permit other input frequencies.
