GR_PLOT_FFT_F(1)						   User Commands						  GR_PLOT_FFT_F(1)

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.

OPTIONS

       -h, --help
	      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]
