HP / Agilent 4194A Impedance / Gain-Phase Analyzer
The HP / Agilent 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 HP / Agilent 4194A can
contribute to improving engineering productivity and reducing test cost.
The analyzer is flexible and has a wide measurement capabilities in both
impedance and transmission measurements, plus it is fully programmable
using Auto Sequence Programming (ASP). Desired measurements and
computations, including graphics analysis, can be programmed simply by
storing front panel keystroke operations, allowing you to customize
measurement, computation and analysis functions. The HP / Agilent 4194A
also features high accuracy and error elimination functions to ensure
reliable measurements.
