The HP/Agilent 4291B RF impedance/material analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials. The HP/Agilent 4291B uses a direct current-voltage measurement technique, opposing the reflection measurement technique, for more accurate impedance measurement over wide impedance range. 

4291A/B

• Basic accuracy of 0.8%
• Internal generator sweeps from 1 MHz to 1.8 GHz with 1 mHz resolution
• Gain-Phase measurements include amplitude, phase, and group delay
• Impedance measurements include |Z|, |Y|, phase, R, X, G, B, Lp, Ls, Cp, Cs, D, Q, deviation, and deviation %
• DC bias to ±35 V
• GPIB

4291 A/B

• 1 MHz to 1.8 GHz
• Independent parameter selection in 2 channels
• Direct read-out permittivity, permeability (option)
• Versatile analysis (temperature, cole-cole plot, relaxation time)
• Sweep parameters (frequency, ac level, dc bias, temperature)
