General Radio, Precision 1640-A Slotted Line - 900 LB As the basic tool in coaxial impedance measurements, the slotted line remains unsurpassed; its accuracy is absolute, since its standard impedance is the characteristic impedance of a coaxial line. The inherent accuracy of the slotted line, as well as its stability and broad bandwidth, led to the investigation of the limitations of this instrument for low VSWR measurements.
