Hi Ariel,

What kind of interface do you use to measure pico-second resolutions? Are
you talking measurements from only one instrument at a time?

In our work even at 1 Hz levels we encounter issues like time-syncing
different measurements since we interface many different instruments with
one main data acquisition unit. This is mainly due to one instrument sits
under the far edge of a wing the other one is inside the cabin sampling air
from outside. It is usually a good idea to sample fastest the system and
probes permits, in the end they would be easily averaged to a lower
acceptable resolution range.

Your job should be very hard indeed if you are dealing with a couple
different instruments at that high measurement rates.
