I'm going to use the Vector Analyzer model E5062A to measure the input impedance of an RFID tag. According to the measurement method proposed by Pavel V. Nikitin (Nikitin, P.V.; Rao, K.V.S.; Martinez, R.; Lam, S.F.; , "Sensitivity and Impedance Measurements of UHF RFID Chips," IEEE Transactions on Microwave Theory and Techniques, vol.57, no.5, pp.1297-1302, May 2009), the tag is connected to the VNA and the output power must be set to a certain level. Please show me how to do this. Thank you for your support.
