The HP 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 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, 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 4194A features a wide test frequency range - 100 Hz to 40 MHz for impedance measurements (10 kHz to 100 MHz when using the HP 41941A/ B Impedance Probe Kit) and 10 Hz to 100 MHz for gain-phase measurements. Realistic device characteristics can be analyzed under actual operating conditions by varying the test frequency, test signal level, and dc bias. The HP 4194's high degree of measurement accuracy- 0.17% for impedance measurements (1.5% when using the HP 41941A/ B) with an amplitude ratio of 0.1 dB - ensures that you'll improve the quality of your test devices. Options. Opt 350: 50 Ohm System. Opt 375: 75 Ohm System. Opt 001: High Stability Frequency Reference.
