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 sine wave outputs of 1 Mhz, 5 Mhz and 10 Mhz with outstanding spectral purity and long-term stability.

The base price includes three sine wave (any combination of 1 MHz, 5 MHz, or 10 MHz) and one 1 PPS square wave. Optionally, up to five additional sine wave outputs are available in any combination of 1 MHz, 5 MHz, and 10 MHz.

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 clock and RAM in the GPS receiver module.

  • Atomic frequency performance at low cost
  • Produces traceable standard frequencies at 1 MHz, 5 MHz and 10 MHz
  • 1 PPS output provided for time standard applications
  • Supports up to eight 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
