Frequency standard

Novatech Instruments has announced the model 2975AX disciplined quartz frequency standard that can generate a synthesized output of any frequency from 100 Hz to 20 MHz with a resolution of 1 µHz. The output is internally locked to an oven-enclosed quartz crystal time base that enables a stability of ±5 × 10^–11 per day when disciplined to a 1 pulse/s source, with daily aging better than ±1 × 10^–10 during holdover. The synthesized output frequency is automatically saved in EEPROM, so after a power interruption, the output remains the same. The 2975AX uses an auto-adaptive algorithm that tracks the 1 pps from a GPS receiver or smart antenna and provides outputs of 5 and 10 MHz. The front-panel display allows users to set the output and also indicates the 1-pps tracking status. Novatech Instruments Inc, P. O. Box 55997, Seattle, WA 98155-0997, http://www.novatech-instr.com
