2 meters, rms
Seventy-two (72) channel receiver: L1 GPS/SBAS C/A, L1 GLONASS CT, Galileo, and BeiDou.
- 40 seconds typical, cold start
- 25 seconds, typical, warm start

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
- 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
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.
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.
- 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.
One Form C (SPDT) fail-safe, 0.3 A at 130 Vdc; configurable to Out-of-Lock, Fault, Alarm, Stabilized, or Programmable Pulse
|Keyboard||Eight keys; select display functions or setup menus|
|RS-232||1200 baud to 230,400 baud; 7 or 8 data bits; 1 or 2 stop bits; even/odd/no parity
AUX OUT can provide programmable pulse function at RS-232 levels
|Connector||Male 9-pin D-subminiature|
