I tried reading the 5335 over GPIB. In the case where I am measuring frequency I get the expected number of digits. In the case where I am measuring A->B, I only get nanoseconds (e.g 3E-9; or 4E-9). On my scopes, I was able to measure the delta at 3.28 nanoseconds with both scopes close within .01 nanoseconds. I was measuring the delta between 1M and 11.5” of RG316 cable. With a published velocity factor of .695 and 3.28E-9 seconds difference, the delta came out to 27” vs the measured 27.87”. Of course the RG316 VF wasn’t accurate to the number of digits needed to get any closer. I was demonstrating the precision of the equipment I was using to my son who is becoming somewhat of a mad scientist like his father.
