• Fully programmable

The 4194A impedance/gain-phase analyzer is an integrated solution for efficient measurement and analysis or go/no-go testing of components and circuits. Detailed impedance and transmission characteristics, including secondary parameter derivations, can be simply and quickly evaluated or tested. The 4194A can contribute to improving engineering productivity and reducing test cost. The analyzer is flexible and has wide measurement capabilities in both impedance and transmission measurements, It is also fully programmable using Auto Sequence Programming (ASP). Desired measurements and computations, including graphics analysis,can be programmed simply by storing fron-panel keystroe operations, allowing you to customize measurements,computation, and analysis functions. The 4194A also features high-accuracy and error elimination functions to ensure reliable measurements.
