NoiseTech Microwave Ltd. IG0160C Impedance Generator

NoiseTech Microwave’s 0.1MHz to 6GHz impedance generator (P/N IG0160C) is specifically designed for “cold” noise-parameter measurements.


The IG0160C is an impedance tuner which, at each frequency point within its bandwidth, can be switched through four impedance states. At each frequency, one state will be in each of four impedance regions.

The device is controlled by a USB connection to a host computer and can be switched using a simple terminal console connection, or using Matlab or LabVIEW.

Noise parameter measurements are based on the cold noise parameter measurement procedure. The connection, control and cold noise measurement procedure is described in the accompanying documentation.
