    5. OTHERS 5-1. BNC Cable Considerations Accuracy of radio frequency measurements can be affected by connections between signal source and counter. Main considerations are standing waves and shunt cable capacitance. Standing wave is usually present due to reflections when a transmission line is not terminated in its characteristic impedance.

  • Page 22: Line Frequency Measurements

    5-3. Line Frequency Measurements Use of the attenuator, low pass filter, and/or x10 probe is advisable when measuring line frequency because the high amplitude signal and noise can cause wrong counting. WARNING USE CAUTION IN MEASURING THE LINE FREQUENCY OF AN AC OUTLET. USING THE PROBE TIP ONLY, MEASURE BOTH SIDES OF THE LINE.
