Abstract

1364956 Determining transmission line frequency characteristic SIEMENS A G 18 Sept 1972 [17 Sept 1971] 43103/72 Heading G1U A swept frequency of constant amplitude from a source 2, 3, Fig.1, is applied to a transmission line AB under test, the voltage of the signal emitted by the line is sampled and its amplitude digitized 6, at particular times in the sweep under control of a counter 13, gates 14, 17, ..., 18, and an oscillator 11 triggered by a sync pulse from the source 2 immediately prior to the sweep, and the resulting digitised values are transmitted, via an appropriate coupling device 7, to arecorder, such as a tape punch 8.
