Chapter 1 Overview
Functional Description
Time Inputs
The SyncServer S6x0 can use GNSS, NTP, and IRIG as external input references
(depending on model and configuration). The NTP signals use the RJ45 (1 - 4)
connectors on the rear panel. The GNSS reference uses a BNC connector on the
rear panel. The IRIG signal uses a BNC connector (J1) on the optional Timing I/O
module on the rear panel, as described in Table 1-1.
Frequency Inputs
The SyncServer S6x0 can use either 1PPS, 10 MPPS, 10 MHz, 5 MHz, or 1 MHz as
external frequency input references. The 1PPS/10 MPPS use the J1 BNC and the
10 / 5 / 1 MHz signals use a BNC connector (J2) on the Timing I/O module on the
rear panel, as described in Table 1-1.
Frequency and Timing Outputs
The SyncServer S6x0 can provide NTP,10 / 5 / 1 MHz, 1PPS, IRIG, or TOD output
signals. The NTP signals use the RJ45 (1 - 4) connectors on the rear panel. The
serial TOD output connects to a DB9 connector (DATA/SERIAL) on the rear panel.
The IRIG, PPS, 10 MPPS, and 10 / 5 / 1 MHz signals use BNC connectors (J3 - J8)
on the Timing I/O module on the rear panel. A 1PPS output is also available using a
BNC connector (1PPS) on the rear panel.
