NAME

       gr_plot_fft_f - plot complex binary data using GNU Radio

SYNOPSIS

       gr_plot_fft_f: [options] input_filename

DESCRIPTION

       Takes a GNU Radio complex binary file and displays the I&Q data versus time as well as the
       frequency domain (FFT) 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. This value defaults to
       1000. 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.

              show this help message and exit

       -B BLOCK, --block=BLOCK
              Specify the block size [default=1000]

       -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]
