• One coil connected to a RF generator and another coil connected to an oscilloscope couple inductively when close.  When separated, the inductive signal fades but the RF signal remains fairly constant.
  • The coils are on separate carts, so the generator cart can be moved away while the oscilloscope cart remains stationary.
  • The oscilloscope can be connected to the classroom projector for better visibility.
        (use 100 MHz oscilloscope, and 80 MHz generator set for 10 Vp-p sine wave at 9 MHz)
