I've been wondering about this.
Some SMA connectors are rated for 200 to 500 screw/unscrew cycles only, if rated at all. 500 is for Amphenol's $60/piece type. (wow.... expensive!) I've seen 200 for common ones. I personally have damaged threads few times with far, far, less. As I understand it, it was originally designed for internal component connection, not an external interface. Yet, I've seen images of NIST lab using them for latter. I wonder about this from time to time. I do not like BNC as I can see readings change just pushing on the connector lightly.
Has anyone in DMTD world or really anyone had their measurement error because of this? I used N connector for this reason. I can see myself doing 10 ocxo tests at a time and easily exceeding this rather low rating.
Corby:
I've just aligned my second best 11801 for 10MHz + 10Hz duty. I can't wait to get the new TIC! I've suspended my effort to use my other counters for now. I feel like chasing an ever moving target.
Ed:
It is odd that I'm always having wrapping problems and you don't have it or rarely. As I understand it, most counters around year 2000 and before has this dead-time issue. What kind of counters do you have? I used TICC, 53132A and 5335A.
