Attached, please find the file.
This is a photo of a HMC764 evaluation board that has been set for frequency of 7437.5 Mhz in fractional mode. There are two spurious very close to the interest frequency. How can I get rid of these spurious signals at your evaluation board?
The second attached photo shows the output when I am using a 125Mhz external crystal oscillator which its specifications are similar to internal crystal clock. There are lower spurious but higher noise floor.
