Re: RF out with RF OFF: Clock feed through

This is exactly what I did, I have a connectorized 30 MHz LP filter and I inserted it between the input and the output of the PHSNA. This time it is not a harmonic problem, it is the 180 MHz refclock frequency which is not well filtered out.

Try putting a low pass filter of 30mhz at the output of the dds-60. The amplifier of the dds60 also adds harmonics.
