Overview
- class finesse.detectors.quantum_noise_detector.QuantumNoiseDetectorDemod1(name, node, f, phase, nsr=False, sources=None, exclude_sources=None)[source]¶
Bases:
Detector
,NoiseDetector
Represents a quantum noise detector with 1 RF demodulation.
It calculates the amplitude spectral density of the photocurrent noise of a photodiode output demodulated at the signal frequency.
- Parameters
- namestr
Name of newly created quantum noise detector.
- node
Node
Node to read output from.
- ffloat
Demodulation frequency in Hz
- phasefloat
Demodulation phase in degrees
- nsrbool, optional
If true, calculate the noise-to-signal ratio rather than the absolute noise value.
- sourceslist of
Connector
, optional If given, only detect quantum noise contributions from these components.
