The Series 2000 Antenna Tuning Indicator is a tool which simplifies the resonance tuning of the antenna (Section 2.2) and the adjustment of the RXSS- (Section 2.3) synchronization level for wireless read cycle synchronization. It indicates exactly what to do during the antenna tuning procedure. In addition to that, the output of the RF Module field strength detector is indicated (RXSS-level) for EMI control.
