Model 1202B/C GNSS Synchronized Clock - 1

ARBITER SYSTEMS Time and Frequency Specifications subject to change. Enhanced Performance and Security The Arbiter Systems®, Inc. Model 1202B/C GNSS Synchronized Clock is a multi-satellite system (GPS/ GLONASS/Galileo/BeiDou) timing source for precision applications. Arbiter Systems' next-generation substation clock provides enhanced performance and security (EPS) while supporting the standard outputs and popular options of our existing clocks. EPS benefits include multi-system timing sources, standard holdover oscillator, multiple levels of user security, secure communications, and anti-spoofing technology. The Model 1202B/C is compatible with Arbiter Systems' earlier clock models, supporting the same legacy options and outputs, while enabling the transition to a more secure device. The Model 1202 is available in two versions. The Model 1202B has eight status LEDs, an LCD setup/ status back-lit display, and a keyboard. The Model 1202C adds a large (20 mm or 0.8 in) LED time display. Both versions have 72 receiver channels, capable of tracking all visible GNSS satellites simultaneously, providing optimum performance. The Model 1202B/C has 100 ns worst-case accuracy to meet the requirements of a broad range of applications from relay synchronization to synchrophasor timing. The standard holdover oscillator maintains 1 ms/24 h accuracy when not tracking satellites. In addition to enhanced performance, Arbiter Systems' new EPS technology provides six levels of user security selectable from Level 0 security (none) to Level 5 security (front panel display, keyboard, and legacy serial commands disabled). Spoofing concerns are a thing of the past with patent pending anti-spoofing algorithms, multi-system satellite tracking, and holdover oscillators that limit the time error to the holdover oscillator specification. If spoofing is suspected/detected, the user is alerted by the ALARM indicator. Six BNC outputs (3 programmable high-drive and 3 jumper configurable) provide IRIG-B unmodulated, 1 PPS, and Programmable Pulse, Modulated IRIG-B outputs along with an Event Input. The three high drive outputs are independently set to any of the programmable pulse modes and provide ±125 mA of drive current. The three configurable outputs are selectable for 5 V CMOS bus drivers (± 75 mA drive capability); 4 Vpp, 20 ohms source impedance (IRIG-B modulated only) drivers; or an event timer channel with 100 ns resolution. The event function may be driven by the start bit of a received character on the serial port or an external 5 V CMOS/TTL signal on one of the bNc connectors. The Model 1202B/C comes standard with one DB-9 communication port and the option to add a second port. An RS-422/485 transmit only driver is standard on the main communication port. Two SPDT (form C) fail-safe relays are also included and are configurable to Out-of-Lock, Fault, Alarm, Stabilized, or Programmable Pulse. The Model 1202B/C accepts one or two power supplies in a redundant configuration. Standard power options include a universal 100 Vac to 240 Vac/100 Vdc to 350 Vdc or 24 Vdc to 48 Vdc supplies with secure terminal strip inlets and surge-withstand capability. The surge-withstand network is designed to meet aNsI/IEEE C37.90-1 and IEC 61000-4 specifications. Available options include Four Additional Configurable Outputs; High Drive IRIG-B Outputs; Power System Time, Frequency, and Phase Monitor; NTP/PTP Server.
