Measurement testing uses the cascaded LMX1204 reference design in conjunction with the AFE7950 EVM. The clock source is the Wenzel Oscillator pre-multiplied to 1474.56 MHz. The AFE7950 is programmed to for a 5898.24-MHz sample clock. The numerically controlled oscillator in the AFE7950 is set to 3500 MHz. The digital baseband signal is nearly 10 MHz. The DAC data rate is 491.52 MSPS; the ADC data rate is 245.76 MSPS. Figure 3-2 illustrates the measurement setup.
