Chapter 3 Installing the TimeSource 3100
Making Cable Connections
DCD Shelf without Isolation Module
If an isolation module is not required, use two 50 ohm coax cables to make the
connections to the DCD Shelf. Cables must not exceed 15 meters, and must be
purchased separately or are to be user-supplied.
Source Other than DCD Shelf
If an isolator kit is not required, connect an RG-59/U coaxial cable from a 5 MHz or
10 MHz remote oscillator to the connector labeled REM OSC A. Connect another
RG-59/U coaxial cable from a remote oscillator of the same frequency to the
connector labeled REM OSC B. Both remote oscillators must be the same
frequency, and a minimum of Stratum 2 (rubidium oscillator) quality. See Figure 13.
for the connector locations.
Installing a Module for Additional E1 or Analog Outputs
Connect the optional eight E1 or analog outputs with the wire-wrap or BNC output
module. See Figure 3-8 for the connector location, and Figure 3-13 for the
connections.
