AD9988 EVM result

Hi folks,

I find the specification and relevant document, it doesn't mention about EVM measurement .

Could you help to provide the EVM measurement result , the condition of measurement is 1024QAM@7.2GHz


  • Hi, please see the prelim results collected on single AD9082 board. AD9988/AD9082 are same product family. please refer to the Datasheet/UG to understand the difference.

    1 ADC- DAC Loopback EVM

    ►Single Channel Loopback EVM

    • Using IEEE 802.11ax waveform with 80MHz instantaneous BW, QAM 1024 symbols
    • Wide capture bandwidth enables waveform frequency shifting to avoid spurs

    Complex mode EVM is expected to be 3dB lower than the single channel EVM
