Jumper wire

1Build four test connectors using BNC connectors and 6-by-2 sections of Berg strip:

a Solder a jumper wire to all pins on one side of the Berg strip.

b Solder a jumper wire to all pins on the other side of the Berg strip.

c Solder two resistors to the Berg strip, one at each end between the end pins.

d Solder the center of the BNC connector to the center pin of one row on the Berg strip.

e Solder the ground tab of the BNC connector to the center pin of the other row on the Berg strip.
