NIST Requirements Vector Signal Generator & Signal Analyzer

I. Background/ Scope This acquisition is requested in support of the project “Atom-Based Metrology” in Atom-scale device group (Nanoscale Device Characterization division) who are currently capable of fabricating Phosphorus donor-based quantum devices (single electron and single atom transistors) at the atomically precise scale in silicon using hydrogen resist based STM lithography. The vector signal generator is being procured to demonstrate coherent spin manipulation in quantum device consists of a single donor atom tunnel coupled to a single electron transistor island in a parallel configuration at cryogenic temperatures. To meet this mission, this acquisition is for a vector signal generator for performing various experiments such as electron spin resonance, Rabi Oscillations, and spin coherence measurements, etc.

The signal analyzer is to measure these quantum devices using high frequency (> 40 GHz) signals in cryogenic environment. These measurement demands to create various form of amplitude, phase, I/Q modulated signals. For routine characterization of high frequency signal in frequency and time domain is current requirement, which requires a signal analyzer.
