Measuring VHF Detector Linearity Using A Quantum-Based Source, CPEM 2024

Data sets for measuring VHF detector linearity using a Josephson Arbitrary Waveform Synthesizer (JAWS). Two instruments are measured: an RF power sensor and a fast ADC. The VHF-JAWS source consists of a chip with 12,810~~Josephson junctions located in a cryocooler and driven to produce quantum-based ac waveforms at frequencies up to 50.05~~MHz and power up to -19dBm. We first confirm that the device is operating correctly by measuring the dc offset quantum-locking range (Fig. 2) and then measure the system output power with an RF power sensor (Fig. 3, bottom) and a high-speed digitizer (Fig. 3, top). After removing an overall scale factor, the ten-nanowatt scale differences between the programmed JAWS values and the measured values (Fig. 3, top and bottom) indicate better than $\pm$0.5$%$ DUT linearity for frequencies in the VHF band.
