Bases:
Detector
,NoiseDetector
Represents a quantum noise detector with 2 RF demodulations.
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.
- f1float
First demodulation frequency in Hz
- phase1float
First demodulation phase in degrees
- f2float
Second demodulation frequency in Hz
- phase2float
Second 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.
