equipment. In addition it violates safety standards of design, manufacture, and intended use
of the instrument.
The Agilent Technologies assumes no liability for the customer’s failure to comply with
these requirements.
• Ground The Instrument
To avoid electric shock hazard, the instrument chassis and cabinet must be connected to
a safety earth ground by the supplied power cable with earth blade.
• DO NOT Operate In An Explosive Atmosphere
Do not operate the instrument in the presence of flammable gasses or fumes. Operation
of any electrical instrument in such an environment constitutes a definite safety hazard.
• Keep Away From Live Circuits

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.
