I tested OCXO 128.3333M with +12V power, the power cable length is 1.5m. I soldered a 100uF Tan Cap to 12V trace of OCXO power. And I tested the spur at 140K is -84dBc. The seller test result is almost same as me. The seller tested with a special fixture.
My question is:
1. How to reduce the spur? Any other ideas?
2. Any special power supply circuits need for the OCXO to reject any spur?
