Hello, In tutorial 4 (pocket correlator) the python file poco_adc_amplitudes.py reads the values from the adc_sum_sqN registers and calculates the RMS as:
inputs[input]['unpacked'] = fpga.read_uint(regname) inputs[input]['rms'] = numpy.sqrt(inputs[input]['unpacked']/(2.0**16))/(2**(8-1)) I believe "numpy.sqrt(inputs[input]['unpacked']/(2.0**16))" calculates the RMS, but why is this divided by (2**(8-1))? Is this just a scale factor, and if so, how was it chosen? Thanks, Pam Ford
