Cryogenic Impedance Tuner
The CT-series cryogenic automated tuner is driven by an external controller, which connects to the tuner through included wiring, and is USB-controlled via direct SCPI commands.

Solid-state automated impedance tuner designed for use down to 4K
Perform noise parameters (NP) measurements on unmatched transistor or existing LNA
Evaluate noise and gain circles and determine the best impedance match that meets design requirement
Build matching network that optimizes LNA performance
