Most of the day was spent making BNC cables and checking a program for errors. The steps to make a BNC are:
 
# Cut the length of cable needed.
# Place the end of the cable up against the wire strippers, and rotate the stripper four times.
# Expose the central conducting wire. Then expose the dielectric insulation, removing any straggling wires with a dike.
# Slide the strain suppressor and the short metal cylinder from the BNC connector kit on. Spread out the wires.
# Slide the small metal prong onto the inner conductor wire, cutting off any strands that get in the way. Clamp it tightly on.
# Slide the large metal piece on, and wrap all of the strands around it.
# Pull up the metal piece around the wire strands. Clamp it into place tightly and pull up the strain reliever, covering the connection between the cable and connector.
# Check that a current can pass between the inner wire (prongs) and the out wires (surrounding casing). Ensure that no current can get between the prongs and outer casing on either end. If a current can pass between a prong and the casing, that means that the connection is faulty and needs to be made again, or the cable will short circuit.

BNC Cables

Most of the day was spent making BNC cables and checking a program for errors. The steps to make a BNC are:

  1. Cut the length of cable needed.
  2. Place the end of the cable up against the wire strippers, and rotate the stripper four times.
  3. Expose the central conducting wire. Then expose the dielectric insulation, removing any straggling wires with a dike.
  4. Slide the strain suppressor and the short metal cylinder from the BNC connector kit on. Spread out the wires.
  5. Slide the small metal prong onto the inner conductor wire, cutting off any strands that get in the way. Clamp it tightly on.
  6. Slide the large metal piece on, and wrap all of the strands around it.
  7. Pull up the metal piece around the wire strands. Clamp it into place tightly and pull up the strain reliever, covering the connection between the cable and connector.
  8. Check that a current can pass between the inner wire (prongs) and the out wires (surrounding casing). Ensure that no current can get between the prongs and outer casing on either end. If a current can pass between a prong and the casing, that means that the connection is faulty and needs to be made again, or the cable will short circuit.
