     display_qt - a Gnu Radio Example gr-qtgui

DESCRIPTION
     Display a GUI using QT of a sine wave in noise.

     Example  program  instantiates  a  GNU  Radio flow graph using a sine wave
     source, a noise source, and gr-qtgui blocks. This new (in version  3.7.10)
     example shows how to build a C++ only QT based application.

usage: gr_plot [-h]

               [-B BLOCK] [-s START] [-R SAMPLE_RATE]
               FILE [FILE ...]

Takes a GNU Radio binary file and displays the samples versus time. You can
set the block size to specify how many points to read in at a time and the
start position in 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 axis, set the sample rate (-R or --sample-rate) to the sample rate used
when capturing the samples.

positional arguments:
  FILE                  Input file with samples

options:
  -h, --help            show this help message and exit
  -d, --data-type {complex64,float32,uint32,int32,uint16,int16,uint8,int8}

  -B, --block BLOCK     Specify the block size [default=1000]
  -s, --start START     Specify where to start in the file [default=0]
  -R, --sample-rate SAMPLE_RATE
                        Set the sampler rate of the data [default=1.0]

root@kali:~# gr_plot_const -h
usage: gr_plot_const [-h] [-B BLOCK] [-s START] [-R SAMPLE_RATE] FILE

Takes a GNU Radio complex binary file and displays the I&Q data versus time
and the constellation plot (I vs. Q). You can set the block size to specify
how many points to read in at a time and the start position in 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 axis, set the sample rate
(-R or --sample-rate) to the sample rate used when capturing the samples.

positional arguments:
  FILE                  Input file with complex samples

                   [-B BLOCK] [-s START] [-R SAMPLE_RATE]
                   FILE

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.

positional arguments:
  FILE                  Input file with samples

options:
  -h, --help            show this help message and exit

root@kali:~# gr_plot_iq -h
usage: gr_plot_iq [-h] [-B BLOCK] [-s START] [-R SAMPLE_RATE] FILE

Takes a GNU Radio complex binary file and displays the I&Q data versus time.
You can set the block size to specify how many points to read in at a time and
the start position in 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 axis, set the sample rate (-R or --sample-rate) to the sample rate
used when capturing the samples.

                   [--psd-size PSD_SIZE] [--spec-size SPEC_SIZE] [-S]
                   FILE

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.

                        different specs.
