Microchip Model 5071B Cesium Primary Frequency Reference Standard

The Microchip 5071B Primary Time and Frequency Standard is a replacement for the 5071A that matches the form, fit and functions of its predecessor. All connections and commands remain unchanged. We updated the 5071B’s internal electronics with modern circuitry, including our microprocessors (MPUs), to ensure continuity of supply for all components into the next decade and achieve RoHS compliance. We tested the 5071B over 18 months against an extensive set of qualifications to confirm that this device meets or exceeds all performance specifications.

Key Features:

• Frequency Accuracy up to ±5e-13
• Long Term Stability up to 1e-14
• 4 x Frequency Outputs
• 3 x 1PPS Inputs
