Example measurement of sham hause wiring by DTF function

The point of 1.44m corresponds to the distance between MA430 and the distributer 1. Similarly, the points of 2.89m, 3.96m and 5.52m correspond to the distributer 2,3 and 4. The point of 6.29m in tarminated corresponds to the end 2, the level is low.
Some traditional TDR instruments can detect only end points as reflectin points, and they are no good at resolution of distance, and are not quick at the response of measurments. Compared with them, On the other hand, MSA438TG+DTF(MA430) ac hieves the high resolution and the quick response. Our DTF instrument can from 1m to 800m cable for 50 Ω, so it corresponds the wiring （10 to 100m）, and the trunk line (200to800m) in a genenal hous and an apartment.
