10K Compensated Sapphire Oscillator
Frequency Standards Laboratory


The 10K CSO is a new short-term frequency standard now under development at JPL in support of the Cassini Ka-band Experiment. This standard is designed to achieve the highest possible short-term stability while allowing long-term operation by use of a cryocooler instead of liquid helium.
