For components with voltage and current dependency, such as RF inductors or ceramic capacitors, the DC bias function (Option E4991A-001) supplies DC voltage (±40 V) and current bias (±50 mA) across the device. You can easily observe your device behavior under various DC bias conditions without using an external DC bias source.
The Agilent 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 percent. High Q accuracy enables low-loss component analysis.
The internal synthesizer sweeps frequency from 1 MHz to 3 GHz with 1 mHz resolution.
Options 001 DC B1AS, 002 material measurement firmware, 010 probe station connection, 1D5 high stability frequency reference.
