原廠英文說明
The 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 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.
The E4991A provides the total dielectric/magnetic material measurement solutions in wide frequency range (1 MHz to 1 GHz). The E4991A-010, Probe Station Connection Kit, enables us to easily connect the Agilent E4991A to a RF probe system from Cascade Microtech for making on-wafer impedance measurements. The temperature characteristic test kit, the E4991A-007, is a new solution of temperature characteristic measurement for components and materials.
This option provides highly accurate temperature characteristic analysis capability within the wide temperature range from - 55C to + 150C with a powerful temperature drift compensation function.
