Figure 5From: Local oscillator port integrated resonator for Rydberg atom-based electric field measurement enhancement(a) Measured SNR versus EIT specturm shift under 100 KHz detuned frequency. (b) Measured SNR versus detuned frequency of LO signal under 2.6 MHz EIT specturm shift. (c) The SNR as a function of S11 relative to a fixed LO and antenna power. (d) Results from the Rydberg-atom superheterodyne, plots of the beat-note intensity of the spectrum analyzer as functions of signal generatorBack to article page
