Function
Hosts the main output oscillator, producing the microstepper output frequency. The output frequency is used as a reference frequency for the DDS-board, and as input for the PICDIV-board. Takes phase-detector input from the MIXER-board.

OCXO testing, February 2019
This image shows phase-noise/ADEV results from a prototype OCXO-board with an ON300 100MHz OCXO divided by /10 to 10MHz.
The ADEV of this OCXO seems to turn around at 1..2e-11 between 10ms and 100ms.
