What are jumpers P15 and P14 controlling?  They are not discussed in the user guide.

  • Emily,

    This is for providing an external bias to the DUT. Please see the User Guide, pg.21 at the top.

    Thanks, Chuck

    How do you apply an external bias (using the EVM)? Does it replace the internal bias (1.6V)? What is the range of an acceptable external bias?

    Chuck,

    Any update on how to apply an external bias and what the limitations of the bias are?

    Emily, my previous answer was incorrect. This in output used for biasing the analog input if you want to use DC coupling.

    Hi Chuck,

    So is there no way to change the internal bias from 1.6V to something lower?  I am working with a signal that has a Vref of around 1.2V.
