Keysight E4991A RF Impedance/Material Analyzer

• 3 GHz impedance direct read-out
• Basic accuracy ±0.8%
• Windows-styled user interface
• Sweep parameters (frequency, ac level, dc bias)
• Built-in VBA programming function
• Various test fixture for components
• Data transfer through the LAN interface

The Keysight 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 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 Ω accuracy enables low-loss component analysis. The internal synthesizer sweeps frequency from 1 MHz to 3 GHz with 1 MHz resolution.
