Page 22: 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. These standing waves may cause damage to the signal source or produce inaccurate measurements, and their effects increase as cable length reaches one-fourth of the wavelength for the frequency being measure.
