Abstract
The transmission of a repeater section consisting of 4 miles of coaxial cable and a repeater including equalizing networks was measured in the laboratory. The measuring circuit was switched between the unknown and a short reference strap at a rapid rate. This reduced the effects of level drifts in the measuring oscillator amplifier and detector to a point where an accuracy of ±0.001 decibel over a range of ±0.05 decibel was obtained. The measurements were automatically recorded in pen and ink over a frequency range of 0.1 to 8.3 megacycles.
