I purchased evaluation board of adf4108
I am using the internal VCO and without changing anything
I connected 240MHz as reference signal (0dBm) to the board
I connected spectrum analyzer on VCO/2
VCO terminal wan not terminated nor any other port
I confegured the software correctly
the measured power of signal is -20dBm only on the VCO/2
is this normal? is there any thing I should do? or it is now burned?
is terminating VCO port is important?
Is it correct to use VCO/2 as an output port?
Thank you very much in advance
