2210A & 2211A QUARTZ FREQUENCY STANDARDS

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.
A range of options are available to enhance the functionality of the unit including disciplining from an external reference for improved long term stability, multiple frequency outputs and a DC power supply.
Refer to the Configuration Options table for complete list.
