Paper Abstract

HYPRES, Inc. has introduced to the commercial marketplace a Sampling Oscilloscope/Time Domain Reflectometer (TDR) based on Josephson junction technology. The unit offers measurement performance commensurate with the inherent high speed of the Josephson elements, e.g., bandwidths in excess of 70 GHz and rise times on the order of 5 ps. A Josephson {rigger recognizer and delay circuit allows triggering of the sampling oscilloscope from the signal itself, with full view of the trigger point. Input modules offering different sensitivities or TDR capability are quickly interchangeable, and operating temperature is achieved in less than one minute. The technical details of the cooling technique and the chip circuitry will be described in this paper .
