run_test_transfer(chnl: int, func_mux, func_set_daq, func_sens, func_get_daq, func_beep) → dict[source]#

Function for characterizing the transfer function of the Amplifier

Parameters:

  • chnl – Integer number for testing the channel

  • func_mux – Function for defining the testmode of the hardware DUT with defining the channel (chnl)

  • func_set_daq – Function for applying selected voltage/current signal on DAQ with input params (data)

  • func_sens – Function for getting the applied voltage/current (sensing) from DAQ device

  • func_get_daq – Function for sensing the DUT-amplifier output from DAQ

  • func_beep – Function for do a beep in DAQ

Returns:

Dictionary with [‘stim’: input test signal of one repetition, ‘settings’: Settings, ‘rpt’: Test results]
