Please help me with eval board ADF411x!
I have purchased this board and I want to generate frequency from 2GHz to 3 GHz so I bought IC PLL 4113, VCO (CVCO55BE 1600 3200 from Crystek) and SDP-S board. I also installed Analog Devices N-interger PLL (ver 7.7.4) successfully. When i connect device to PC and set output frequency to 2 GHz, the software says that values have been written to device but the result showed on Spectrum analyzer is different (1,6 GHz), i try to set other output frequency of 2,5 GHz Spectrum analyzer indicates the same one (1,6GHz), nothing changes. And i seems that PLL does not lock because the lock detect Led does not emit. Please help me!
