I discovered today that the my tek 2252 scope effectively has a time interval counter that at first glance seems to provide similar resolution to my HP 5370B. The propagation delay function can be used to measure the time interval between signals on ch 1 and ch 2. Looking at 10 Mhz signal from one of my GPSDOs and my new to me Rb oscillator, I'm seeing the change in time interval displayed with a resolution of .01 ns. I fed the same signals via T connectors into my 5370B and the relative readings seem to match fairly closely. The progation delay function will also helpfully display negative and positive values. I wouldn't consider this a replacement for my 5370B but it was a pleasant surprise to find this. I'll have to find or purchase a manual for this scope and see what other features it has. (It does have the ability to accept an external time base, and has a GPIB interface.) Considering I paid less for my 2252 scope than I did for my 5370B I'm fairly pleased with this.
I believe other Tektronix scopes also have similar abilities. I thought someone might be interested in this.
