Setting modulation frequency to 0 is a hacky way of displaying DC voltages. It doesn't work perfectly for 2 reasons:

  • Demodulation is not actually turned off, scaling down the acquired DC voltage. This can be seen by changing scopegen_adc_a_sel": self.csr.signal("fast_a_out_i") to "scopegen_adc_a_sel": self.csr.signal("fast_a_x")
  • RedPitaya's ADC calibration factors are not considered. Not sure whether they are properly documented or whether we have to analyze their FPGA code for that
