herosdevices.hardware.menlo.dds¶

HERO driver for a DDS-based RF output of a Menlo Systems frequency comb.

Module Contents¶

class herosdevices.hardware.menlo.dds.DDS(ofc: herosdevices.hardware.menlo.ofc.OFC, funclayer_identifier: str, observables: dict[str, dict[str, str]] | None = None)[source]¶

Bases: herosdevices.hardware.menlo.functional_layer.FunctionalLayerModule, herosdevices.interfaces.atomiq.RFSource

Driver for a DDS-based RF output of a Menlo Systems frequency comb.

Wraps one functionalLayer.<funclayer_identifier>Settings sub-tree of an already-running OFC.

This covers only the bare DDS output. For a module that additionally has a closed feedback loop locking the DDS to a reference (a beat-note PLL), use LaserLock instead.

Polls DEFAULT_OBSERVABLES for observable_data with live reads from the OFC, superseding the RFSource interface’s own cached-value observable.

Parameters:

ofc – The OFC HERO this DDS output belongs to.
funclayer_identifier – Identifier of the module’s functional-layer settings object, e.g. “cw1112_1” for the sub-tree at functionalLayer.cw1112_1Settings. Use ofc.explore(“functionalLayer”) to find the identifier for a given module.
observables – Additional observables to poll, merged on top of DEFAULT_OBSERVABLES, see FunctionalLayerModule.

amp_max: float = 1.0¶

amp_min: float = 0.0¶

freq_max: float = 100000000.0¶

freq_min: float = 0.0¶

DEFAULT_OBSERVABLES: dict[str, dict[str, str]]¶

property output_enabled: bool¶: Whether the DDS output is enabled.

ofc¶

base_path¶

observables¶

get(relative_path: str) → Any¶

Read the current value of a node relative to this module’s settings object.

Use this for module properties not already exposed as a named attribute. See explore() to find the available relative paths, e.g. ofc.explore(module.base_path, depth=2).

Parameters:: relative_path – Dotted path relative to base_path.
Returns:: The current value of the node.

set(relative_path: str, value: Any) → None¶

Set the value of a node relative to this module’s settings object.

Parameters:

relative_path – Dotted path relative to base_path, see get().
value – Value to set.

frequency: float = 1000000.0¶
