Thanks a lot for your comment Bruce, I need to feel a bit deeper the ins and outs of the methods so I guess I will anyway implement both methods on an evaluation PCB and characterize each method. This will bring to me some actual data to compare. I will share the results of course. The plan

Actually I'm working in the RF department of a big lab, designing RF electronics mainly in microwaves range. I'm luckilly having some tools around to play with and a lot of components like mixers/amplifiers/couplers/splitters/attenuators, ... almost whatever the frequency is up to several tens

Dear all, I'm trying to measure Alan Deviations using Timelab and some frequency counters. The device under test is a GPSDO using a TCXO as référence I've an HP58503B GPSDO which feeds my counters. I've tried an HP5342A, 0-18 GHz, 1 Hz resolution and a Philipps PM6654C, 0.01Hz resolution.
