[time-nuts] Using 5335 frequency counter for timing

[David]

My Racal-Dana 1992 is the same way; its time interval mode is limited
to the 1 nanosecond interpolated resolution of the counter.

Some counters support time interval averaging which will produce much
much higher resolution but often they have a minimum time interval.

If the transmission line to be measured is configured as a shorted
line, then the pulse width can be measured instead to determine the
line length and pulse width averaging is much more commonly supported.

I used a scope to measure the offset and was then thinking the 5335 could do it more accurately, but I was wrong, as it only reports to the nanosecond.  I thought I had seen somewhere where people were getting higher resolution using software along with the 5335, no?
