MMW-STUDIO mmW and Sub-THz characterization software, offered by Maury Microwave and Vertigo Technologies, is a software suite designed to work with a 4-port VNA using waveguide extender modules and add accurate and repeatable high-resolution power control. The software enables the direct measurement of vector corrected power at the DUT reference plane, as well as control over the power delivered to the DUT. Doing so allows engineers to perform gain compression power sweep measurements over the available level of powers, and to perform S-parameter measurements at any arbitrary power level.
MMW-STUDIO LP is a software add-on, which when used in conjunction with a Vector Modulation Unit (VMU), enables control over the magnitude and phase of the signals delivered to the input and output of the DUT. This enables an engineer to set arbitrary impedances, or perform active load pull measurements, where the magnitude of reflection presented to the DUT is achieved by controlling the reflected a2 wave and fulfilling Γ=a2/b2.
