Code for the ROACH CUKIDS readout and analysis.

This code is provided in the hope that it may be useful to others, but is still very much a work in progress.

Using the ROACH code requires the FPGA designs available here:

• Simulink .slx files (public): https://github.com/ColumbiaCMB/kid_readout_fpga
• Compiled .bof files (private): https://github.com/ColumbiaCMB/kid_readout_fpga_bof

• apps/ Scripts, mostly for acquiring and analyzing data
• docs/ Documentation
• kid_readout/ All library code
  • interactive.py Import * from this for interactive use
  • analysis/ Resonator fitting, timeseries analysis, experiment info (in resources/)
  • equipment/ Scripts and library code for lab equipment
  • measurement/ Code for organizing collected data and writing it to disk
  • roach/ Communicate with ROACH 1 and 2 boards
  • settings/ Local variables and settings
  • utils/ Miscellany, mostly deprecated
• ppc/ ROACH PPC code

From the directory where this package was cloned, first create an environment named kid_readout with all dependencies: conda env create -f environment.yml

Activate the kid_readout environment: $ source activate kid_readout

At this point, all of the non-hardware tests should pass: $ nosetests -v

All dependencies should be installed, so it should be possible to install the package in development mode: $ pip install --no-deps -e .

This is a hack to stop the corr package from importing lots of things we don't use, one of which raises an error: $ echo "" > $CONDA_PREFIX/lib/python2.7/site-packages/corr/__init__.py At this point, all the hardware tests should pass if the corresponding readout hardware is connected:

$ cd kid_readout/roach/tests
$ nosetests -v test_roach2_heterodyne_loopback.py
