# miri\_sdr(1)

an I/Q recorder for Mirics SDR devices

## 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 \[-f freq\] \[OPTIONS\] \[output file\]**

## OPTIONS

- \-f frequency\_to\_tune\_to \[Hz\]

  - \-m sample format (default: auto)

  - 504: S8 (fastest)

  - 384: S10 +2bits

  - 252: S14

  - \-e USB transfer mode (default: 1)

  - 1: Isochronous (maximum 196.608 Mbit/s)

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

  - \-i IF mode (default: ZERO)

  - 0: ZERO

  - 450000: 450 kHz

  - 1620000: 1620kHz

  - 2048000: 2048kHz

  - \-w BW mode (default: 8MHz)

  - 200000: 200kHz

  - 300000: 300kHz

  - 600000: 600kHz

  - 1536000: 1536kHz

  - 5000000: 5MHz

  - 6000000: 6MHz

  - 7000000: 7MHz

  - 8000000: 8MHz

  - \-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).
