    Hi Erik,

    A few things that can impact distortion.

    1. Running the test mode waveform on all channels at once will increase distortion due to coupling
    2. Poor magnetic performance

    Please have the test mode active on only the channel under test.

    Please share your magnetics/schematics if possible.

    And use the following app note for the distortion test settings: www.ti.com/.../snla239a.pdf

    Best Regards,
