describe

The integrated current-voltage (IV) and CV measurements give you confidence in the capacitance voltage (CV) measurements

The Keysight B1520A multi-frequency capacitance measuring unit (MFCMU) in the Keysight B1500A series is backed by years of LCR instrumentation technology and knowledge. It will further extend the precision capacitance measurement capabilities of the Keysight B1500A semiconductor device analyzer. Keysight B1500A integrates MFCMU and power/measurement unit (SMU) functions to perform basic IV measurements and a variety of capacitance measurements such as CV, c-t, c-f, and quasi-static CV (qs-cv) and is therefore a comprehensive IV and CV measurement solution. For semiconductors, carbon nanotubes (CNT), carbon nanowires (CNW), active/passive components, materials, and any electrical device requiring precise IV and CV measurements, B1520A, combined with the analytical and data management capabilities of EasyEXPERT software, is well suited for IV and CV characterization of these devices.
