Paul, the Adret 4110 is great for frequency difference measurements and adjustments.
For serious ADEV measurements, it's just too noisy on low tau's and has too much temperature drift / long term phase instability on high tau's. See the attched noise floor test. I have a 4110 with a paper op and service manual. parts of it are in French only.
