Things to check

[top]

• It is good to have each pin come to a pin array which has the following:
  • Main pins to clip on or plug into
    • Outermost pin as the signal itself
    • Followed by GND
    • Followed by signal
    • Followed by VDD
  • Socket pins to insert components into
    • GND
    • SIGNAL times 2 (2 rows of signal sockets)
    • VDD
  This array allows for a variety of connections to the signal
• If you are using a socket make sure there is enough clearance around the socket so that the clips or lid can open easily
• Make sure there are enough GND points to clip on to your instruments
• Make sure there are enough jumpers to isolate parts of the circuit so you can selective measure current of desired parts of the circuit.
