A Basic measuring setup, of signal generator bridge and detector wide band detector often used with single-frequency generator, but a narrow band detector (receiver) must be used if the signal source IS wide band. such as noise generator or a swept fre- quency oscillator B) Basic four arm bridge. usually designed for equality of the upper and lower arms The standard arms may be a center tapped trans- former or two resistors. or may be more complex. The series adjustable arm type S good for dipoles below resonance as shown for the series RC unknown element. Parallel arms may also be used as in the GR RF ...
