NAME

miri_sdr - an I/Q recorder for Mirics SDR devices

DESCRIPTION

Software for the Mirics MSi2500 + MSi001 SDR platform

In-Phase and Quadrature Phase data can faithfully represent all of the information in a band of frequencies centered on a carrier signal frequency.

USAGE

This program captures information from a band of frequencies and outputs the data in a form useful to other software radio programs.

(a '-' dumps samples to stdout)

EXAMPLES

Example: To tune to 392.0 MHz, and set the sample-rate to 1.8 MS/s, use:

./mirisdr /tmp/capture.bin -s 1.8e6 -f 392e6

to record samples to a file or to forward the data to a fifo.

If the device can't be opened, make sure you have the appropriate rights to access the device (install udev-rules from the repository, or run it as root).
