2210A & 2211A Quartz Frequency Standards

Precise Time and Frequency, Inc. (PTF)

The ptf 2210A Quartz Frequency Standard has been designed to provide a highly stable and spectrally pure frequency reference for applications requiring the ultimate in short term frequency performance.
The instrument contains a double oven controlled stress compensated (SC cut) quartz crystal oscillator (OCXO) to give the ultimate in performance.
Ideal for laboratory or system use, the unit provides good stability performance at lower cost and with improved phase noise.
