Efforts are underway to develop a low cost DMTD apparatus with demonstrated stability measurements of 1E-13 in 1s. It seems that existing TI counters can reach this goal in 10s. (using MDEV estimate or 100+s. using ADEV estimate). The question is; does the MDEV tool provide an appropriate measure of stability in this time range, or is the ADEV estimate a more correct answer?
The TI performance I'm referring to is the 20-25 ps, single shot TI, typical for theHP5370A/B, the SR620 or the CNT81/91. I have data from my CNT81showing MDEV < 1E-13 in 10s. and I believe the other counters behave similarly. I would appreciate any comments or observations on this topic. My motivation is to discover the simplest scheme for making stability measurements at this performance level; this is NOT even close to the state-of-the-art, but can still be useful.
