Incoming Inspection
Warning
Toavoid hazardous electrical shock, do not turn on the HP 4284A
when there are signs of shipping damage to any portion of the outer
enclosure (for example, covers, panel, or display)
Inspect the shipping container for damage. If the shipping container
or cushioning material is damaged, it should b e kept until the
contents of the shipmenthave been checked for completeness and
the HP 4284A has b een checked mechanically and electrically. The
contents of the shipment should b e as listed in Table 1-1. If the
contents are incomplete, if there is mechanical damage or defect, or if
the analyzer do es not pass the p ower-on selftests, notify the nearest
Hewlett-Packard oce. If the shipping container is damaged, or the
cushioning material shows signs of unusual stress, notify the carrier
as well as the Hewlett-Packard oce. Keep the shipping materials for
the carrier's inspection.

Introduction
Product Introduction
This Chapter provides the information you will need to know b efore
operating the Hewlett-Packard Model 4284A Precision LCR Meter.
Before using the HP 4284A, read through this Chapter so you can
quickly and eciently learn the HP 4284A's operation.
The HP 4284A is a general purpose LCR meter for incoming
inspection of components, quality control, and laboratory use. The
HP 4284A is used for evaluating LCR components, materials, and
semiconductor devices over a wide range of frequencies (20 Hz to
1 MHz) and test signal levels (5 mV to 2 V
With Option 001 the HP 4284A's test signal lev

The HP 4284A oers C-D measurements with a basic accuracy of
6
0.05% (C),60.0005 (D) at all test frequencies with six digit
resolution (the dissipation factor resolution is 0.000001) on ev
ery
range.
With its built-in comparator, the HP 4284A can output
comparison/decision results for sorting comp onents into a maximum
of ten bins. By using the handler interface and scanner interface
options, the HP 4284A can easily b e com
bined with a component
handler, a scanner, and a system controller to fully automate
component testing, sorting, and quality control data processing.
).
The HP 4284A's new list sweep function p ermits entry of up to ten
frequencies, test signal levels, or bias level points to be automatically
measured.
The HP-IB interface is a standard interface on the HP 4284A
and can b e used to build an automatic test system to completely
characterize new components and materials, and to fully automatic
production line testing.
The HP 4284A with Option 002 can apply a 0 to 20A (Maxim um
40A : When two HP 42841As are paralleled.) DC current bias to
the DUT (Device Under Test). So, high current biased imp edance
measurement of coils or transformers can be performed easy, fast and
safe.

Description
The HP 4284A has eight measurement ranges: 10, 100, 300, 1
k, 3 k, 10 k, 30 k, and 100 k. When Option 001 is installed,
the HP 4284A has nine measurement ranges: 1, 10, 100, 300,
1 k, 3 k, 10 k, 30 k, and 100 k. The measurement range is
selected according to the DUT's impedance even if measurement
parameter is capacitance or inductance.
Figure 3-3 shows the display range and eective measuring range for
jZj
each measurement range while in the impedance mode (
, R, X).
For example, 50 k DUT impedance can be measured using from
the 100 to the 30 k range, but the HP 4284A's measurement
accuracy specication is only met by using the 30 k range. If this
DUT is measured by the 100 k range,
Figure 3-3. Effective Measuring Range for Each Measurement Range

will be displayed.
Figure 3-4 and Figure 3-5 show the eective measuring range of each
measurement range, in which the HP 4284A's measurement accuracy
meets its specication. When the measurement range is set manually,
the optimum measurement range should be selected by matching
the DUT's imp edance to the eective measuring range shown in
Figure 3-4 and Figure 3-5. When the measuremen

according to the impedance of each DUT.

On this page, only the Integration Time in the above items can be

The HP 4284A uses an integrating A/D converter in the internal
circuits to convert the analog signal to a digital signal. The
Integration Time is the time required to perform an A/D con

Generally, a longer conversion time will result in more stable and
accurate measurement results. SHORT, MEDIUM, or LONG

Description
The HP 4284A's built-in comparator can sort devices into a
maximum of ten bins (BIN 1 to BIN 9 and the OUT OF BINS bin)
using a maximum of nine pairs of primary limits and one pair of
secondary parameter limits. Also, a device whose primary parameter
is within limits, but whose secondary parameter measurement result
is not within limits can be sorted into an AUXiliary BIN. The
comparator function is especially useful when using the HP 4284A
with a component handler (handler interface option is installed).
These limit settings for bin sorting are only set on the

You can enter a comment using the numeric entry keys (

(period)) on the comment line eld. This comment line is
405to495,4-5
stored to the internal non-volatile memory or to the external memory
card with the HP 4284A control settings. Also this comment line is
loaded from the internal non-volatile memory or from the external
memory card with the control settings. A comment can be up to 30
characters long.
When you wanttoenter the ASCII characters on the comment line,
only the
DISPlay:LINE
HP-IB command must b e sent via HP-IB.

Description
The HP 4284A has four trigger mo des: INT
ernal, EXTernal,
MANual, and BUS.
When the trigger mode is set to INT trigger mode, the HP 4284A
continuously repeats measurements on any display page under
4

.
When the trigger mode is set to MAN trigger mode, the HP 4284A
performs a single measurementonany display page under

When the trigger mode is set to EXT trigger mode, the HP 4284A

every time a p ositive going TTL pulse is applied to
the EXT TRIGGER connector on the rear panel. External triggering
can be also b e achieved by momentarily switching the center
conductor of the EXT TRIGGER connector to chassis ground (center
conductor circuit contains a pull-up resistor). Figure 4-3 shows the
required TTL pulse.
