Hello,
I'm currently building a GPSDO with a 10MHz output and have a Rev. D ADALM-Pluto.
My question is if there is any advantage in multiplying the 10MHz reference to 40MHz (either through PLL or harmonic multiplier) vs feeding the 10MHz directly and adjusting the frequency in software?
I ask this as there is some info about phase noise performance being better when feeding with 40MHz reference, however I'm not sure if the extra phase noise caused by multiplication wouldn't be greater than Pluto's added noise.
