Figure 2-25 DAC Output CHA Spectrum, JMODE 1, Interpolate by 4 at 20GSPSDACA is getting the modulated LFM chirp. A full 20GHz span is shown (two Nyquist zones). The second Nyquist image suppression is provided by DES2XL mode.
Figure 2-26 DAC Output CHB Spectrum, JMODE 1, Interpolate by 4 at 20GSPSDACB is generating a sinlge 3GHz tone by DDS. A full 20GHz span is shown (two Nyquist zones). A second Nyquist image suppression is provided by DES2XL mode.
