RF DAC - RFSoC

Jump to solution

Hi,

We have configured the DAC to accept I/Q data of required frequency and tried the two options available in RFDC IP Block:

1.IQ to REAL 

2.IQ to IQ

At the output of Spectrum analyzer in both the cases ,Required frequency along with Image frequency(fs-required freq) were observed ,Please suggest measures to eliminate image frequency at the output of DAC.

Board Used is ZCU111.

Hi @nmurthy 

Image frequencies will be present as you are monitoring the direct DAC output.

At the receiver end (ADC) you need to have proper frequency planning to eliminate the image frequencies.
