Best Choice For LF/HF
Testing
Precise Ceramic Capacitor
Measurements
1 kHz and 1 MHz are the primary
testing frequencies for ceramic
materials and capacitors. The
HP 4284A can test at these
frequencies while maintaining an
excellent accuracy and 6 digits of
resolution.
Make Production Test Easier
The HP 4284A and HP 4285A
reduce testing costs by providing
accurate high throughput test
platform. The built-in comparator,
cable compensation and I/O
interfaces permit system
integration. Operation setup
errors can be reduced by storing
and recalling instrument states
from memory cards or internal
memory.
Power Supply's Components
Performance Evaluation
Production Testing
Direct Q measurements with
the HP 42851A Precision
Q Adapter
Ceramic Capacitor Evaluation
Semiconductor Testing
The HP 4284A and HP 4285A
allow you to evaluate the C-V
characteristics of semiconductors
at multiple frequencies. Small ac
test signal levels and an accurate
DC Bias can be applied so that
you can evaluate the C-V
characteristics.
Dielectric Evaluation
The HP 4284A and HP 4285A
provides the accuracy, resolution,
high test signal and bias levels
required for material
measurements. Using the
HP 16451B Dielectric Test Fixture
provides you with accurate
dielectric and dissipation factor
(loss tangent) measurements.
Designing advanced switching
power supplies require the use of
inductors and transformers that
operate in high frequencies. For
low frequencies, the HP 4284A,
the HP 42841A and the
HP 42842A/B all combine to form
a 40 Adc bias test system. For
high frequencies, use the
HP 4285A, the HP 42841A, and the
HP 42842C to achieve up to
10 Adc biasing measurements at
30 MHz.
The HP 4285A and HP 42851A
provide you with excellent Q
accuracy at the resonant
frequency. Tuning Operation,
calculation of the measured
values, and compensation are fully
automated, thus improving
measurement efficiency and
reliability.

High Accuracy with wide
Impedance Range
The HP 4286A RF LCR Meter
offers accurate and reliable
measurements. This will allow
you to evaluate your components
and improve circuit design. The
HP 4286A employs a RF I-V
measurement technique, as
opposed to the reflection
measurement technique, yielding
an accurate impedance
measurement that extends way
beyond 50Ω.
Precise RF Inductor
Measurements
The expanding wireless
communication market is rapidly
increasing the use of RF
inductors. The HP 4286A provides
you with an accurate impedance
measurement capability for RF
inductors, especially for nH
values. Q measurement accuracy
has been improved due to HP's
advanced calibration technique ;
typical Q accuracy is 6% @ 100
MHz (Q=100). You can reduce the
design uncertainty by measuring
your devices true impedance
values at operating conditions.
Ease-of-Use
The HP 4286A can be easily used
by pressing the front panel keys.

Option (1C2), the HP 4286A
allows you to customize
measurement, test sequences,
process control, and perform data
analysis. A number of new APC-7
SMD test fixtures can be
connected with the HP 4286A; you
don't need to build your own
fixture.
HP 4286A Applicable Fixtures
RF Inductor for Testing
Simplified Handler Integration
The HP 4286A is designed to test
RF components in a production
line. The 1m/3m selectable test
head cable can be easily
connected closely to the handler
DUT (device under test) contacts
without additional error. The
built-in comparator function, a
HP-IB interface and a Handler
interface are available for
integration with a component
handler.
Reliable and High Throughput
Testing in Production Line
The HP 4286A allows you to
reduce test time and improve
testing efficiency and reliability.
The measurement time is 15
milliseconds. Using the working
standard set option (004) with the
calibration/compensation
functions minimizes the fixture
parasitic residuals, allowing you
to test the actual component
characteristics.
