kalibrate

Python wrapper for Kalibrate.

https://travis-ci.org/ashmastaflash/kal-wrapper.svg?branch=master Maintainability Test Coverage

Returns scan data in structured format.

Example usage:

import kalibrate
scanner = kalibrate.Kal("/usr/local/bin/kal")
# Scan a band
band_results = scanner.scan_band("GSM850", gain=45)
# Scan a channel
channel_results = scanner.scan_channel("232", gain=45)

And what you get for scanning a band:

[{'band': 'GSM-850',
'base_freq': 869200000.0,
'channel': '128',
'channel_detect_threshold': '259970.196875',
'device': '0: Generic RTL2832U OEM',
'final_freq': '869175933',
'gain': '45.0',
'mod_freq': 24067.0,
'modifier': '-',
'power': '299318.41',
'sample_rate': '270833.002142'},
{'band': 'GSM-850',
'base_freq': 890000000.0,
'channel': '232',
'channel_detect_threshold': '259970.196875',
'device': '0: Generic RTL2832U OEM',
'final_freq': '890022169',
'gain': '45.0',
'mod_freq': 22169.0,
'modifier': '+',
'power': '780303.16',
'sample_rate': '270833.002142'}]

Channel scan results:

{'device': '0: Generic RTL2832U OEM',
'channel': '232',
'band': 'GSM-850',
'gain': '45.0',
'sample_rate': '270833.002142',
'frequency': '890MHz',
'average_absolute_error': '-33.445',
'measurements':
['29921.37',
'29952.37',
'29900.71'],
'raw_scan_result': 'ORIGINAL FULL SCAN BODY GOES HERE'}

Note: Kalibrate's output for this feature starts numbering with offset 1. This abstraction starts at 0, because that's how Python numbers things. So you'll find your measurement for the first offset labeled "offset 1:" in the original output, and in channel_scan["measurements"][0] in the output of the channel scan. This format is new in version 2 of this library, and is a breaking change from the way v1 presented this information.
