Operation
DESCRIPTION
DESCRIPTION
The 16334A Testfixture was designed for use with the following instruments:
4192A LF lmpedance Analyzer
4194A lmpedanoe/Gain-Phase Analyzer
4274A Mu-ti-Frequency LCR Meter
4275A Multi-Frequency LCR Meter
4276A LCZ Meter
4277A LCZ Meter
4278A 1kHz/1MHz Capacitance Meter
The 16334A is a direct attachment, 4-terminal pair type fixture which is equipped with a
tweezer type probe for measurement of leadless components such as chip capacitors.
The tweezer tips are replaceable. The distance between the tweezer tips is continuously
adjustable according to the distance between the DUT terminals. A compensation block is
furnished for compensation to be minimize the effects of residual impedance and the stray
admittance.
The specifications of the 16334A are given in Table 1-2, and the typical characteristics are
shown in Figure 1-2, and listed in Table 1-3.

*1.There are some cases where the actual incremental error exceeds this limit when this fixture is used with an 4192A
or 4275A.
*2.The maximum measurement frequency of the 4277A and 4278A is 1 MHz, so the incremental error is available
only for 1 MHz measurements.

ZERO OFFSET ADJUSTMENT
ZERO OFFSET ADJUSTMENT
The 16334A has inherent residual impedance and stray admittance that affects the accuracy
of the measurements. To compensate for, or negate, these residuals in order to minimize
measurement error, the instrument’s zero offset adjustment procedure should be performed.
The zero offset adjustment procedure is described in the instrument’s manua1. When
performing the zero offset adjustment, use compensation block Agilent PN 16334-60001
(furnished with probe). An illustration showing how to use the compensation block is
shown in Figure 1-3.

OPERATION
OPERATION
Setup and measurement procedure is as follows:
1. Set the instrument’s cable LENGTH to 1m.
2. Connect the 16334A directly to the UNKNOUN terminals of the instrument.
3. Perform the ZERO offset adjustment described in the instrument’s operation manual.
4. Connect the DUT to the 16334A test fixture.
WARNING DO NOT APPLY MORE THAN ±42V OF DC BIAS VOLTAGE TO THE
UNKNOWN TERMINALS. AN ELECTRICAL SHOCK HAZARD WILL EXIST
DURING OPERATION WHEN THE DC BIAS VOLTAGE IS GREATER THAN
±42V DC.

Maintenance
An exploded view of the 16334A (for parts identification) is shown in Figure 2-1. Do not
disassemble any further than shown. Maintenance consists principally of cleaning contacts
and replacing worn or damaged parts. Take special care when cleaning contacts. To order
parts, use the Agilent Technologies part numbers listed in Table 2-12-1. If a faulty part is
located in an assembly that cannot be disassembled, order the next higher assembly or
