Re: SMA caps for sampling heads


Hi Reginald,

How did you find out the operating hours and power up figures? I have an 11403A and there is nothing in the Utility Menus that would give me that kind of information.

Just a wild guess but given your figures the 11801 was running an average of 22 hours each time it was powered up. Could it have been in some kind of installation where they used the scope on a daily basis, but always shut it off at the end of the day?

To make another even wilder guess, if it was used all day long and into the night before being turned off each time then it would make sense to assume it was used for 22 hours per day on average for 2,000 days average. That comes out to about 500 days that it was used. That would equate to about 2 years that it was in use like this.

This is nothing more than wild speculation on my part. I must be momentarily bored. More likely I am avoiding something unpleasant I have to do.

A termination would present the same issue of wear. I'm not going to
be monitoring a data link 24x7, so I'll be connecting and disconnecting
more often. My 11801 had 44,000 operating hours but was only powered
up 2000 times.
