NAME¶

gr_plot_const - constellation plot of I&Q data using GNU Radio

SYNOPSIS¶

gr_plot_const: [options] input_filename

DESCRIPTION¶

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.

OPTIONS¶

-h, --help

-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]
