The small adjustable capacitor in a 10:1 probe is set so that

  • A.the probe resonates with the input capacitance of the instrument
  • B.the probe presents a purely resistive impedance at the highest frequency used
  • C.the attenuation is the same at all frequencies
  • D.the input capacitance of the probe is reduced to zero

Answer: C

The divider must attenuate by ten for direct voltage and for the fastest edges alike, which requires the capacitive division to match the resistive one. A square wave of known shape is displayed and the trimmer set until the top of the wave is flat.
