Schematics (panel a) and photographs (panel b) of the experimental setup. The setup consists of a full Band-9 2SB receiver including an IF hybrid (A), a second down-conversion stage (B), and a digital back-end (C). An extra set of components, (D), is introduced to test the calibration stability with demagnetization and defluxing. This diagram also shows the RF source used for calibration and the components needed for implementing the Kerr method of measuring SRRs (E).
