Cryogenic Variable-Temperature Noise Source
Measurement Infrastructure
The Cryogenic Variable-Temperature Noise Source is a diagnostic tool that adds a controlled amount of noise to an input line, making it possible to calibrate the intrinsic noise of a device under test.
The Cryogenic Variable-Temperature Noise Source is used to calibrate the intrinsic noise of a device under test, such as a microwave amplifier.
When installed on the Cold Plate, the noise source can be operated at temperatures between 0.1 K < T < 5 K without causing significant heating in the experimental space. Importantly, this dynamic range enables the user to calibrate the noise added by both quantum-limited parametric microwave amplifiers and HEMT amplifiers.
