Hi, We are comparing the output signals coming from X2M200 with X4M03. We are getting absolute baseband amplitude values from X4M03 between -0.5 to 0.5 while the amplitude value for X2M200 module connector MATLAB respiration example code is coming in the range of 0 - 100. I have been looking at the datasheets and understood sweep controls, can this be a difference of DAC min max and pulse+iteration values? If so, can I know the reference settings provided in fw of X2M200? We are typically using what is given in the example code for X4M03: Code: # Set DAC range r.x4driver_set_dac_min(900) r.x4driver_set_dac_max(1150) # Set integration r.x4driver_set_iterations(16) r.x4driver_set_pulses_per_step(26) In such short amplitude, we are experiencing trouble in separating noise from the target. Can you please point us to the right direction? Another statement that I am not able to understand in the matlab example is: Code: [frame, ctr] = radar.GetFrameNormalized(); That is only present in X4M03 code, can this be a problem?
