spektralwerk-scpi-client 0.3.1

Spektralwerk SCPI communication library

spektralwerk_scpi_client

spektralwerk_scpi_client is a Python library for communicating with Spektralwerk NIR spectrometers via their SCPI interface.

The library supports all available configuration settings as well as the retrieval of spectral data.

The API supports two ways of obtaining spectra:

• single spectrum mode: returns a single spectrum upon request. Intended for use cases like exploratory spectroscopy in the lab or requests triggered by the trigger in interface
• streaming streaming mode: returns a continuous stream of spectral information. Intended for process analytics, in-line spectrometry in production and other situations demanding very high sample rates.

Supported Devices

• Spektralwerk Core
  • set/get exposure time
  • set/get average number
  • set/get offset voltage
  • set/get light and dark reference spectrum
  • get pixel count and wavelengths array of the spectrometer
  • get single raw spectrum and averaged raw spectrum

Requirements

• Python3
• hatch for development (e.g. pipx install hatch)

Usage

spektralwerk-scpi-client is available via PyPI. To install spektralwerk-scpi-client use pip:
