mahos.inst.tdc.TimeTagger#

class mahos.inst.tdc.TimeTagger(name, conf, prefix=None)#

Swabian Instruments Time Tagger.

Parameters:

  • base_configs (dict[str, str]) – Mapping from base config name to channels and levels definitions. Used in configure_histogram() etc.

  • raw_events_dir (str) – (default: user home) The directory to save RawEvents data.

  • ext_ref_clock (int) – (default: 0) channel to use as external reference clock. Because it uses “software clock” of Time Tagger, clock must be supplied to one of input channel, not “CLK IN” connector. Putting 0 disables the software clock feature.

  • ext_ref_clock_level (float) – (default: 0.0) threshold level in volts for ext_ref_clock channel.

  • ext_ref_clock_freq (float) – (default: 10e6) frequency of ext_ref_clock.

  • remove_ttbin (bool) – (default: True) Remove raw events (.ttbin) file after load.

  • serial (str) – (default: “”) Serial string to discriminate multiple TimeTaggers. Blank is fine if only one TimeTagger is connected.
