Forum Post: RE: regarding AFE 5809 evm with TSW1400

Hi Chandu,

First, I just want to prove that the LPF is working.  I misunderstood and thought you were using the AFE5809 EVM.  Do you still have access the AFE inputs via SMA?  If so, can we set the LPF to 10MHz and use the signal generator to input a sine wave to the AFE at 5,15, and 20MHz .  We should see the fundamental power diminish after 10MHz.  What samplig frequency are you using?

Thanks,
