I get AD9874 evaluation board with HSC-ADC-EVALCZ and try to get any results
internal FREF=26 MHz
internal Fclk=18 MHz
internal LO=16.58 MHz
I don't see anything on average FFT in Visual Analog.
I checked resistors, cable connection and power. It looks ok. DC voltage on TP1(charge pump) is 1,58 V - is it correct?
Please help me, because I don't know where is a problem and how to fix it.
