NAME

       rtl_power: - wideband spectrum monitor utility

DESCRIPTION

       Uses  a  re-purposed  DVB-T receiver as a software defined radio to receive signals in I/Q
       data form. Written for and incorporated in the osmocom rtl-sdr project.

USAGE

       rtl_power, a simple FFT logger for RTL2832 based DVB-T receivers

       This tool gathers signal data over a very wide area of the frequency  spectrum,  and  then
       that data can be used to find active areas of the spectrum.

       Use:    rtl_power -f freq_range [-options] [filename]

       -f lower:upper:bin_size [Hz]

              (bin size is a maximum, smaller more convenient bins

       will be used.
              valid range 1Hz - 2.8MHz)

              [-i integration_interval (default: 10 seconds)]

              (buggy if a full sweep takes longer than the interval)

              [-1  enables  single-shot mode (default: off)] [-e exit_timer (default: off/0)] [-d
              device_index (default: 0)]  [-g  tuner_gain  (default:  automatic)]  [-p  ppm_error
              (default: 0)] filename (a '-' dumps samples to stdout)

              (omitting the filename also uses stdout)

   Experimental options:
              [-w window (default: rectangle)]

              (hamming, blackman, blackman-harris, hann-poisson, bartlett, youssef)

              [-c crop_percent (default: 0%, recommended: 20%-50%)]

              (discards  data  at  the  edges,  100% discards everything) (has no effect for bins
              larger than 1MHz)

              [-F fir_size (default: disabled)]

              (enables low-leakage downsample filter,

       fir_size can be 0 or 9.
              0 has bad roll off,

              try with '-c 50%')

              [-P enables peak hold (default: off)] [-D enable direct  sampling  (default:  off)]
              [-O enable offset tuning (default: off)]

   CSV FFT output columns:
              date, time, Hz low, Hz high, Hz step, samples, dbm, dbm, ...

EXAMPLES

              rtl_power -f 88M:108M:125k fm_stations.csv

              (creates 160 bins across the FM band,

              individual stations should be visible)

              rtl_power -f 100M:1G:1M -i 5m -1 survey.csv

              (a five minute low res scan of nearly everything)

              rtl_power -f ... -i 15m -1 log.csv

              (integrate for 15 minutes and exit afterwards)

              rtl_power -f ... -e 1h | gzip > log.csv.gz

              (collect data for one hour and compress it on the fly)
