Testing BNCs with TDR. how to ?

Tim Phillips <tim@...>

from Tim P (UK)
Could someone explain the procedure for testing the quality of BNC connectors using TDR please ? I have a 7S12 + S6 + S52. Do I need a Tek precision 50 Ohm cable? I have plenty of GR874 h/w, air-lines, power dividers etc.
many thanks
