Package Overview

Drivers

The drivers subpackage is the primary focus of Instrumental, and its purpose is to provide relatively high-level ‘drivers’ for interfacing with lab equipment. Currently it supports:

• Drivers
  • Cameras
    • PCO Cameras
    • PCO Pixelfly Cameras
    • Thorlabs TSI Cameras
    • Thorlabs DCx (UC480) Cameras
    • Photometrics Cameras
    • Picam Cameras
  • DAQs
    • NI DAQs
  • Function Generators
    • Tektronix Function Generators
  • Lasers
    • Toptica FemtoFErb 1560 Laser
  • Lock-in Amplifiers
    • SRS Model SR850 Lock-in Amplifier
  • Motion Control
    • Thorlabs Motorized Filter Flip Mount (MFF10X)
    • Thorlabs K10CR1 Rotation Stage
    • T-Cube DC Servo Motor Controller (TDC001)
    • Attocube ECC100 Motion Controller
  • Multimeters
    • HP 34401A Multimeter
  • Power Meters
    • Newport Power Meters
    • Thorlabs Power Meters
  • Scopes
    • Tektronix Oscilloscopes
  • Spectrometers
    • Bristol Spectrum Analyzers
    • Thorlabs CCS Spectrometers
  • Wavemeters
    • Burleigh Wavemeters

It should be pretty easy to write drivers for other VISA-compatible devices by using VisaMixin and Facets. Check out Writing Drivers for more info. Driver submissions are greatly appreciated!

Other Subpackages

There are several other subpackages within Instrumental. These may eventually be moved to their own separate packages.

Plotting

The plotting module provides or aims to provide

• Unit-aware plotting functions as a drop-in replacement for pyplot

• Easy slider-plots

Fitting

The fitting module is a good place for curating ‘standard’ fitting tools for common cases like

• Triple-lorentzian cavity scans

• Ringdown traces (exponential decay)

It should also provide optional unit-awareness.

Tools

The tools module is used for full-fledged scripts and programs that may make use of all of the other modules above. A good example would be a script that pulls a trace from the scope, auto-fits a ringdown curve, and saves both the raw data and fit parameters to files in a well-organized directory structure.
