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.

SYNOPSIS

       mirisdr [-f freq] [OPTIONS] [output file]

          2:      Bulk (maximum 333Mbit/s, depends on controller type)

       -i IF mode (default: ZERO)

          0:       ZERO

       -s samplerate (default: 2048000 Hz)

       -d device_index (default: 0)

       -T device_type device variant (default: 0)

          0:       Default

          1:       SDRPlay

       -g gain (default: 0 for auto)

       -b output_block_size (default: 16 * 16384)

       -S force sync output (default: async)

       filename
               (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).
