8V97003-EVK

User Manual 8V97003 EVB User Manual Evaluation Board The 8V97003 evaluation board is designed for customers to evaluate the functionality and performance of the 8V97003 RF/Microwave Wideband Synthesizer. On the evaluation board, the 8V97003 device can be programmed and configured with Timing Commander, a PC-based GUI that generates output frequency from 187.5MHz to 18GHz with a very low phase noise and RMS phase jitter. This user manual details the setup of the EVB and the programming of the 8V97003 using Timing Commander. Contents 1.
