The HP 4291A test station connects to your HP 4291A RF
Analyzer so you can extend your test point away from the analyzer without
losing accuracy.
HP / Agilent 4291A RF Impedance / Material Analyzer
The HP / Agilent 4291A 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 4291A uses a direct current
voltage measurement technique, opposing 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. An internal synthesizer sweeps frequency from 1 MHz to 1.8 GHz with 1
mHz resolution. A 1.8m error-less cable connects the analyzer to a test station
so you can extend your test point away from the analyzer without losing
accuracy. Advanced calibration and error compensation function eliminate
measurement error factors in fixtures and assure high accuracy and repeatability
at DUT/MUT.
The HP / Agilent 4291A also provides automatic level control and monitor of
test signals by using IBASIC programming function; devices can be measured under
a constant voltage or current. Measure bias-dependent impedance characteristics
with optional dc bias (up to 40 V and 100 mA). At the push of a button, the
built-in Equivalent Circuit Analysis Function automatically calculates the
circuit constant values of five circuit models.
The HP / Agilent 4291A has two measurement channels; each channel can be set
to measure a single (e.g. 2) or dual (e.g. Z-theta) impedance parameter. The
color CRT with split-display can show both active traces and memory traces
(stored in RAM). A built-in floppy disk drive stores programs and test data in
either LIF or MS-DOS format.
Agilent 4291A Features:
- Basic accuracy ±.08%

- Four component test fixtures (DUT size: 0.5mm to 20 mm)
- Independent parameter selection in 2 channels
- Direct read-out permittivity
- Two material fixtures (operating temperature: -55°C to + 200°C)
- Versatile anaylsis (temperature, cole-cole plot, relaxation time)
- Swept parameters (frequency, ac level, dc bias, temperature
