mahos_dq.meas.spodmr.SPODMR#

class mahos_dq.meas.spodmr.SPODMR(gconf: dict, name, context=None)#

Pulse ODMR measurement with Slow detectors.

Default Worker (Pulser) implements Pulse ODMR using a PG as timing source, and SGs as MW sources.

Parameters:

  • target.servers (dict[str, str]) – InstrumentServer targets (instrument name, server full name). Required keys: sg, pg, names in pulser.pd_names, and the key named by pulser.clock_name. Optional keys: fg, additional SG keys in pulser.mw_channels (for example, sg1), and switch keys listed in switch_names.

  • target.tweakers (list[str]) – The Tweaker targets (list of tweaker full name).

  • target.log (str) – The LogBroker target (broker full name).

  • switch_names (list[str]) – Optional switch instrument names to route signal/optical paths.

  • switch_command (str) – Switch command label passed to Switch worker.

  • pub_interval_sec (float) – Maximum interval between periodic status/data publications.

  • debug (bool) – If True, use DebugPulser instead of Pulser.

  • pulser.pd_names (list[str]) – (default: [“pd0”]) PD names in target.servers.

  • pulser.quick_resume (bool) – default value of quick_resume. If True, it skips instrument configurations on resume.

  • pulser.mw_modes (tuple[int]) – mw phase control modes for each channel. 0 is 4-phase control using IQ modulation at SG and a switch. 1 is 2-phase control using external 90-deg splitter and two switches. 2 is arbitral phase control using IQ modulation at SG (Analog output (AWG) is required for PG).

  • pulser.iq_amplitude (float) – (only for mw_mode 2) amplitude of analog IQ signal in V.

  • pulser.pd_trigger (str) – DAQ terminal name for PD trigger.

  • pulser.trigger_width (float) – (default: 1e-6) pulse width for PD trigger

  • pulser.split_fraction (int) – (default: 4) fraction factor (F) to split the free period for MW phase modulation. the period (T) is split into (T // F, T - T // F) and MW phase is switched at T // F. Thus, larger F results in “quicker start” of the phase modulation (depending on hardware, but its response may be a bit slow).

  • pulser.pg_freq (float) – pulse generator frequency (has preset)

  • pulser.reduce_start_divisor (int) – (has preset) the divisor on start of reducing frequency reduce is done first by this value, and then repeated by 10.

  • pulser.minimum_block_length (int) – (has preset) minimum block length in generated blocks

  • pulser.block_base (int) – (has preset) block base granularity of pulse generator.

  • pulser.nest_blockseq (bool) – (has preset, default: False) allow nested BlockSeq.

  • pulser.channel_remap (dict[str | int, str | int]) – mapping to fix default channel names.

  • pulser.clock_name (str) – (default: "clock") Clock source instrument name.

  • pulser.mw_channels (list[str]) – Optional SG channel identifiers for MW outputs.

  • pulser.pd_rate (float) – (default: 500e3) PD sampling rate in Hz.

  • pulser.pd_data_transfer (str) – Optional DAQ transfer mode label.

  • pulser.eos_margin (float) – (default: 0.0) End-of-sequence timing margin in seconds.

  • pulser.buffer_size_coeff (int) – Buffer size coefficient multiplied by num.

  • pulser.accum_window (float) – (default: 1e-3) Accumulation window in seconds.

  • pulser.accum_rep (int) – (default: 10) Number of accumulation repetitions.

  • pulser.drop_rep (int) – (default: 1) Number of initial repetitions to drop.

  • pulser.lockin_rep (int) – (default: 1) Lock-in repetition count.

  • pulser.every (bool) – If True, publish/refresh data for every update chunk.

  • fitter.rabi.c (float) – default value of param “c” (base line) in RabiFitter. You can set the bounds using “c_min” and “c_max” too.

  • fitter.rabi.A (float) – default value of param “A” (amplitude) in RabiFitter. You can set the bounds using “A_min” and “A_max” too.
