vesna-spectrumsensor 1.0.7

Introduction

This Python module abstracts the serial line protocol used by the VESNA spectrum sensor application and provides a high-level object-oriented Python interface.

Installation

To install system-wide from the package index, run:

$ pip install vesna-spectrumsensor

To install system-wide from source, run:

$ pip install .

To run provided unit tests, run:

$ tox

Usage

The minimal application using this module looks like the following:

# instantiate the SpectrumSensor class using the path
# to the serial device.
spectrumsensor = SpectrumSensor("/dev/ttyUSB0")

# query the attached hardware for supported configurations.
config_list = spectrumsensor.get_config_list()

# get required frequency sweep configuration.
sweep_config = config_list.get_sweep_config(...)

# define callback function that does something with
# measurements.
def callback(sweep_config, sweep):
   ...

# start spectrum sensing
spectrumsensor.run(sweep_config, callback)

Please refer to docstring documentation for details.

The package also installs vesna_rftest script that performs a series of automated hardware tests using a USBTMC attached RF signal generator. Run “vesna_rftest –help” to get a list of available options.
