  • Rigol 1054Z

    Finally received the scope I ordered a week ago. Now it's learning time. It scans my signal generator well but the main reason I bought it was to accurately measure metal detector transmit frequencies. Then use to experiment and continue learning.

    Now what would be the best receiving antenna to attach to my scope probe?

    Seems like a few years ago I used the 5" DD coil that came with my Fisher F75.
    And at that time, I made a small coil, and it worked fine but didn't have a good scope back then.

    Just wind up a small (1-2 inch) coil with 10-20 turns of wire, preferably small gauge (24awg or smaller). Connect it to an oscope probe, you may need a ~1k damping resistor if it rings. This will give you the derivative of the TX field, and will be the same waveform as the TX voltage driving the coil.

      Large coil is 1 1/4" diameter with 20 turns. Measures 0.01 mH and 0.4 ohms.
      Smaller coil is 13/16 diameter with 25 turns. Measures 0.01 mH and 0.3 ohms.
      Used cat 5 solid core wire. Not sure the gauge.

        Any coil you have, with approximately 100 t, any wire diameter.

          Think I'll try one of my mono coils from the White's TDI SL.
          Thanks all.
