Figure 17. DCD Shelf, Isolation Module, and TimeSource 3100 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.
