Model 1201B/C delivers better than 100 ns accuracy and includes the most highly sought after features in a precision time clock as standard plus many enhancements.

Three terminal strip outputs are jumper selectable to unmodulated IRIG-B, modulated IRIG-B, 1 PPS, programmable pulse, or event input. The 1201 is capable of driving multiple loads in parallel.

Like other Arbiter clock models, various options are available to add features such as NTP/PTP (Network Time Protocol/Precision Time Protocol [IEEE 1588]) support, four additional configurable outputs, high drive IRIG-B outputs, power system time, frequency, and Phase Monitor functions, one Form C (SPDT) fail-safe, LOCKED relay that is compatible with 129 Vdc digital fault recorder inputs; plus many more.

Model 1201B/C is available with two front panel configurations (see photos and Key Features tab). Each product includes the GNSS antenna and cable, a terminal power strip, and a rack mount kit, all backed by a Five Year Limited Warranty to the original owner/purchaser.

Optional: OCXO, 10 s/day

I/O Configuration

Output Connectors

Three standard pluggable terminal strip connectors with jumper-selectable signals:
Port 1: IRIG-B unmodulated, 1 PPS, Programmable Pulse or Event Input
Port 2: IRIG-B modulated, 1 PPS, IRIG-B unmodulated, Programmable Pulse or Event Input
Port 3: IRIG-B unmodulated, 1 PPS, Programmable Pulse or Event Input

Output characteristics:

  • 5 V CMOS bus drivers with 10 ohms source impedance and 75 mA drive capability.
  • 4 Vpp, 20 ohms source impedance (IRIG- B modulated only)
  • 400 V, 220 mA, 1 W power dissipation open-drain FET drivers

Output Signals

One IRIG-B channel that controls both the unmodulated and modulated outputs. Configurable to Local or UTC time with C37.118.1 on or off, settings independent from Programmable Pulse IRIG-B output.

Event Inputs

One event timer channel with 100 ns resolution is standard. This function may be driven by the start bit of a received character on the serial port, or an external 5 V CMOS/TTL signal at one of the terminal strip connectors (jumper-selectable).

Programmable Pulse Output

One programmable pulse output (by a jumper connection) that may be output on a terminal strip connector or the AUX OUT pin on either COM port.
Six modes:

  • IRIG-B unmodulated (UTC/Local, C37.118.1 On/Off. Settings are independent from main IRIG-B signal.)
  • Every 1 second to 60,000 seconds, starts top of the second
  • Hourly at a specified offset
  • Daily at a specified time of day
  • One shot at a specified time of year
  • Slow Code (UTC/LCL)

Pulse duration is programmable from 0.01 seconds to 600 seconds, except in one-shot mode, where the output is Low prior to the specified time and High thereafter.

Relay Contacts

One Form C (SPDT) fail-safe, 0.3 A at 130 Vdc; configurable to Out-of-Lock, Fault, Alarm, Stabilized, or Programmable Pulse
