class mahos.inst.pd.APDCounter(name, conf, prefix=None)#

BufferedEdgeCounter for counting APD output pulses.

Parameters:

  • counter (str) – The device name for counter (like /Dev1/Ctr0).

  • source (str) – The pin name for counter source (like /Dev1/PFI0).

  • source_dir (bool) – (default: True) Source direction. True (False) for rising (falling) edge.

  • queue_size (int) – (default: 10000) Software buffer (queue) size.

  • corr_x_kcps (np.ndarray) – x-data of correction factor.

  • corr_y (np.ndarray) – y-data of correction factor.

  • dark_cps (float) – (default 0.0) Module dark count rate.

  • dead_time_ns (float) – (default 0.0) Module dead time in ns. If given, correction factor is calculated using this. And then corr_x_kcps and corr_y are ignored.
