Other Parts Discussed in Thread: LMX2594EVM, , TICSPRO-SW
I can't get the LMX2572EVM to generate desired output frequencies. (I also have an LMX2594EVM and that works fine).
I know the SPI interface is working as I can disable/enable the output. When I set the board to default settings on the GUI (VCO= 6 GHz, RFOUT_A = 3 GHz) then I do see a carrier at ~ 3.7 GHz. I don't think its locking to the input 100 MHz source (I can see the 100 MHz source on a scope). I can remove the 100 MHz external board and I still get the VCO output at 3.7 GHz. When I change the output channel divider to VCO, I expect to see a 6 GHz output, instead I see nothing.
The frequency I want to generate is 4800 MHz. Changing the output frequency to 4800 MHz gives no change to the output spectrum.
