“…'» 2 The results were informative, showing that a differential preamplifier is superior to a preamplifier with a sin,;le-ended input. The rf generator used in these earlier measurements (a vacuum-tester coil) produced an rf spectrum, however, which was not suited to a characterization of rejection as a function of frequency.…”

Radio-frequency signals simulating electrical interference ranging irom 50 kHz to 50 MHz were applied to the shields of tiie input .able system (two solidshielded, mneral-i.isulated c.ibles i>6 ro long) of a wide-band ('-60 MHz) differential preamplifier to determine the comon-raode rejection. Results show that differences in electrical properties and shielding characteristics of the two input coaxial cables along with end effects produced by an unbalanced sensor severely degrade the rejection capability of the differential preamplifier. At 1 MHz, the common-mode rejection without input cables is •>< -70 dB; this is reduced to % -10 dB when measured with the rf signal applied to the surface of the Input cable shields. Measurements of the shielding characteristics of the input cables showed resonances at test frequencies
