Auxilliary outputs of ADF4350

I'm trying to use the RF and Aux outputs as part of a band switching network which removes the harmonic content. Depending on the output frequency, I turn on one or the other but never both. Turning on just the RF output works fine, but when I turn on only the Aux output, I don't get anything from either. Am I missing something?

 

Here are the six register values I'm using at 1499MHz: Regs = 4e08c0, bc01, 4004ac2, 48003, 9990fc, 580005. Note the Main is on and Aux is off.

Here are the six register values I'm using at 1500MHz: Regs = 4e08c0, bc01, 8004ac2, 48003, 99901dc, 580005. Note the Main is off and Aux is on.


The only way I've been able to get the Aux to come on is to leave the main output on also.
