Where applicable, data is provided for the unit and modulation having the worst-case emissions. The KDS and TXC brands of TCXOs were evaluated. The worst-case TCXO was the TXC which is documented in this report. For radiated emissions, the EUT was evaluated in all 3 orthogonal orientations X, Y, and Z-planes. The results presented in this document represented the worse-case orientation, which was the X-plane. The EUT was tested standalone, and a power supply was used to power the EUT. The client provided a PC and optical probe to configure the EUT. Model: SONIXIQV2FCC ID: SDBSONIXIQV2 IC: 2220A-SONIXIQV2 Report: RD72158415.100 TÜV SÜD America Inc.
