|Accuracy Note||Specifications apply at the 1 PPS output, in the presence of Selective Availability (SA), as of date of publication.|
|Accuracy UTC/USNO||± 250 ns peak; < ± 100 ns typical (SA off)|
Twelve (12) channel, C/A code (1575.42 MHz). Receiver simultaneously tracks up to twelve satellites.
- 150 seconds typical, cold start
- 15 minutes, 90 % confidence, cold start
- 40 seconds, with almanac less than 1 month old
- 15 seconds, with ephemeris less than 4 hours old
Four, each with BNC and 5 mm pluggable terminal strip in parallel.
Jumper selectable to high-drive 5 Vdc (250 mA at > 4 V) selectable to:
- IRIG-B00x level-shift,1 PPS orProgrammable Pulse A or B
- IRIG-B12x modulated
- 300 volt MOSFET output.
The MOSFET output is selectable to the same functions as the high drive 5 Vdc output. The MOSFET output is not electrically isolated from instrument common.
Event A Input:
One opto-isolated event capture input with 100 ns resolution, BNC connector jumper-configurable to 5 Vdc to 12 Vdc, 24 Vdc to 48 Vdc and 120 Vdc to 240 Vdc nominal input. Event input is also jumper-configurable to COM 1 and COM 2 RXD line.
Programmable Pulse Output
Two programmable pulse outputs, PPA and PPB. PPA is available (by a jumper connection) on outputs 1, 2 and COM 1 pin 4 (RS-232) and pins 8 and 9 (RS-485). PPB is available (by a jumper connection) on outputs 3, 4 and COM 2 pin 4 (RS-232) and pins 8 and 9 (RS-485).
- Every 1 second to 60,000 seconds, starts top of the minute
- Hourly at a specified offset
- Daily at a specified time of day
- One shot at a specified time of year
- 1 PPS to 1000 PPS squarewave (PPB only)
- Aux IRIG Mode (PPB only)
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, 0.3A at 130 Vdc; jumper selectable to Fault, Unlocked, or Programmable Pulse A (PPA) functions. Fail-safe means the relay indicates ”fault” or ”unlocked” condition with power off.
