Submodules

pyccapt.control.drs.drs module

Python wrapper around the DRS digitizer board library.

Vendor / origin

The DRS evaluation board, the DRS.dll / libDRS shared library, and the underlying DRS4 ASIC are products of the Paul Scherrer Institute (PSI), Switzerland. The native source code under pyccapt/control/drs/source/drs5_lib/ is PSI’s; it is included here so PyCCAPT can be built on machines without a separate DRS SDK install. See source/drs5_lib/ for PSI’s licence (the DRS software is distributed under the GNU General Public License v3 with the additional permission that linking against PSI’s drivers does not constitute a derivative work).

This Python wrapper is local pyccapt code that calls into PSI’s library via ctypes.

class pyccapt.control.drs.drs.DRS(trigger, test, delay, sample_frequency)[source]

Bases: object

This class sets up the parameters for the DRS group and allows users to read experiment DRS values.

Constructor function which initializes function parameters.

Parameters:

  • trigger (int) – Trigger type. 0 for internal trigger, 1 for external trigger.

  • test (int) – Test mode. 0 for normal mode, 1 for test mode (connect 100 MHz clock to all channels).

  • delay (int) – Trigger delay in nanoseconds.

  • sample_frequency (float) – Sample frequency at which the data is being captured.

  • log (bool) – Enable logging.

  • log_path (str) – Path for logging.
