Documentation for Provided Waveforms for IIO Oscope

Hi,

 

Is there any documentation on the waveforms provided with the IIO Oscope application (e.g. qpsknofilt_30M.txt, qpskwithfilt_30.72M.txt, etc)?

 

In general, are the numbers in the filenames represent the sample rate, bandwidth or symbol rate of the modulated signal?  For example, is the qam16_20M.txt file indicate a 16 QAM signal with a sample rate, bandwidth or symbol rate of 20 MHz? 

 

Also, is there any information on what is payload data for each of these modulated signals that would allow a demodulator to acquire and lock onto it? (PRBS, counter, etc.)?

 

Any feedback would be appreciated.
