After applying an external voltage to the board, I was able to get the GUI to write the gains and corner frequencies to the board. Yet, when I connect a signal to INP1_SE and an oscilloscope to OPM1_SE, I am not seeing any output. The signal we are applying is a 5mV P-P square wave at 1 MHz. I have all of the gains set as low as possible and the corner frequency set to 2MHz on the board. I am not sure why I am not seeing any output from the board though.
