Description

GR_PLOT

NAME

gr_plot - display time series of samples from a file

DESCRIPTION

Show data captured using the gnuradio file sink.

usage: gr_plot [-h]

[-d {complex64,float32,uint32,int32,uint16,int16,uint8,int8}] [-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

optional arguments:

-h, --help

-d {complex64,float32,uint32,int32,uint16,int16,uint8,int8}, --data-type
{complex64,float32,uint32,int32,uint16,int16,uint8,int8}

Specify the data type [default=’complex64’]

-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]
