Model 1083B GPS Satellite-Controlled Frequency Standard
Model 1083B GPS Satellite-Controlled Frequency Standard
Model 1083B Frequency Standard/Comparator delivers performance comparable to atomic frequency standards, but at a fraction of the price.
Get atomic frequency references at a fraction of the cost, using Model 1083B GPS Satellite-Controlled Frequency Standard/Comparator.
Suitable for use as the frequency reference for counters and signal generators, or for multiplication to microwave frequencies, Model 1083B features standard outputs of 1 Mhz, 5 Mhz and 10 Mhz with outstanding spectral purity and long-term stability. When used in conjunction the Model 1073A Distribution Amplifier, up to 12 additional 1 PPS outputs are available.
A frequency measurement option allows the 1083B to measure the deviation and Allan Variance of a 1 MHz, 5 MHz, or 10 MHz signal and the deviation of a 1 PPS signal. As with all Arbiter GPS based clocks, the 1083B includes a GPS Data Backup Battery improving acquisition time and supplying constant power to the real-time click and RAM in the GPS receiver module.
- Atomic frequency performance at low cost
- Produces traceable standard frequencies at 1 MHz, 5 MHz and 10MHz
- 1 PPS output provided for time standard applications
- Supports up to eight outputs
- Compatible with Model 1073A Distribution Amplifier for more outputs.
Receiver Characteristics
Timing Accuracy
| Accuracy Note | Specifications apply at the 1 PPS output, in the presence of Selective Availability (SA), as of date of publication. |
| Accuracy UTC/USNO | ±150 ns peak |
| Typical | < 40 ns rms, over 24 hours |
Position Accuracy
10 meters, rms, 90% confidence.
Satellite Tracking
Twelve (12) channel, C/A code (1575.42 MHz). Receiver simultaneously tracks up to twelve satellites. Results from all tracked satellites are averaged in Position-Hold Mode or, with Position-Hold Mode off, using least-squares estimation.
Acquisition
- 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
- The GPS Data Backup Battery is included in the Model 1083B. This feature improves acquisition time by supplying constant power to the real-time clock and RAM in the GPS receiver module.
