signal simulator, a low- noise preamplifier, and a phase detector with a dynamic range exceeding 100 dB. The efficiency of the spectrometer has been tested by studying the NQR spectrum of 14N nuclei ...
rate of 1 GHz based on mature, digitally-controlled, low- noise mode-locked lasers. Compared to conventional lower repetition rate ($\sim$ 100 MHz ) oscillators, this represents a 100 -fold improvement ...
is described. A cooled low noise Schottky mixer receiver in 72-115 GHz range is employed. The back end system comprises three acousto-optical spectrometers (AOS) with bandwidths of 11 MHz , 100 MHz and 600 MHz ...
inductance detector (KID) with resonant frequency from 100 to 200 MHz . We present a characterization of the detector noise performance down to 10 mK measured in a dark setting. We report a device NEP of $$2.7 ...
