this morning, with Vincent Chaumat, we made a beating (phase detection) between the laser 33MHz and the 33MHz coming from the Rigol generator locked by the 10MHz link onto the 500MHz ring generator.

once the laser and the FP-cavity are locked on the RF reference, the 33MHz phase detection is stabilized and confirm the laser/FP-cavity lock on the RF reference.

we plan to make a drift measurement and a jitter measurement to estimate this lock quality.
the 33MHz frequency being quite small, the quality of this estimation will be poor but it can give a "worse case" estimation.
