The E4991A is an impedance analyzer from Keysight Agilent. Electrical impedance analyzers enable the measurement and monitoring of the opposition to current in AC, or alternating current, systems. Impedance refers to how the chemical or physical properties interact with voltages and currents, or how well a component passes current. Use an impedance analyzer to test equipment such as capacitors, inductors, and resistors.
Keysight Agilent HP E4991A Features:
Basic accuracy
+/- 0.8 % basic accuracy
Sweep parameters
Frequency: 1 MHz to 3 GHz
Oscillator level: Up to 1 dBm/0.5 Vrms/10 mArms
DC bias level (Option E4991A-001): +/- 40V or +/- 50 mA
More features
Windows-styled user interface
Built-in VBA programming function
Data transfer through LAN interface
Versatile measurement options
Dielectric/magnetic material measurement (Option E4991A-002)
Reliable on-wafer measurement (Option E4991A-010)

The Keysight Agilent HP E4991A RF impedance/material analyzer offers ultimate impedance measurement performance and powerful built in analysis function. It will provide innovations in R&D of components and circuit designers who evaluate components in the range of 3 GHz. The Keysight Agilent HP E4991A uses an RF-IV technique, as opposed to the reflection measurement technique, for more accurate impedance measurement over wide impedance range. Basic impedance accuracy is +/-0.8%. High Q accuracy enables low-loss component analysis. The internal synthesizer sweeps frequency from 1 MHz to 3 GHz with 1 mHz resolution.
