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.
