Hi You can do a lot better than 5 ns these days if you want to spend some money.
Some low(er) cost alternatives: 5335 counter running GPIB. The counter should be below $150 and it should get you to 1 ns or so. 5334 counter also running GPIB. A bit smaller / cheaper - should be around 2 ns. Both are staple items on the auction sites. You would still need a GPIB adapter and a PC to collect the data and do the analysis. Sounds like you have the PC. The USB adapters aren’t very expensive.
