NAME

       gr_plot_psd_f - plot power spectral density using GNU Radio

SYNOPSIS

       gr_plot_psd_f: [options] input_filename

DESCRIPTION

       Takes  a  GNU  Radio binary file (with specified data type using --data-type) and displays
       the I&Q data versus time as well as the power spectral  density  (PSD)  plot.  The  y-axis
       values  are  plotted assuming volts as the amplitude of the I&Q streams and converted into
       dBm in the frequency domain (the  1/N  power  adjustment  out  of  the  FFT  is  performed
       internally).  The script plots a certain block of data at a time, specified on the command
       line as -B or --block. The start position in the file can  be  set  by  specifying  -s  or
       --start and defaults to 0 (the start of the file). By default, the system assumes a sample
       rate of 1, so in time, each sample is plotted versus the sample number. To set a true time
       and frequency axis, set the sample rate (-R or --sample-rate) to the sample rate used when
       capturing the samples. Finally, the size of the FFT to use for  the  PSD  and  spectrogram
       plots  can  be  set  independently  with  --psd-size  and  --spec-size,  respectively. The
       spectrogram plot does not display by default and is turned on with -S or --enable-spec.

              show this help message and exit

       -B BLOCK, --block=BLOCK
              Specify the block size [default=8192]

       -s START, --start=START
              Specify where to start in the file [default=0]

       -R SAMPLE_RATE, --sample-rate=SAMPLE_RATE
              Set the sampler rate of the data [default=1.0]

       --psd-size=PSD_SIZE
              Set the size of the PSD FFT [default=1024]

       --spec-size=SPEC_SIZE

       -S, --enable-spec
              Turn on plotting the spectrogram [default=False]
