• 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
Operating personnel must not remove instrument covers. Component
replacement and internal adjustments must be made by qualified maintenance
personnel. Do not replace components with the power cable connected. Under
certain conditions, dangerous voltages may exist even with the power cable
removed. To avoid injuries, always disconnect power and discharge circuits
before touching them.
• DO NOT Service Or Adjust Alone
Do not attempt internal service or adjustment unless another person, capable of
rendering first aid and resuscitation, is present.
• DO NOT Substitute Parts Or Modify Instrument
Because of the danger of introducing additional hazards, do not install
substitute parts or perform unauthorized modifications to the instrument.
Return the instrument to a Agilent Technologies Sales and Service Office for
service and repair to ensure that safety features are maintained.
• Dangerous Procedure Warnings
Warnings, such as the example below, precede potentially dangerous
procedures throughout this manual. Instructions contained in the warnings must
be followed.
WARNING Dangerous voltages, capable of causing death, are presenting this instrument.
Use extreme caution when handling, testing, and adjusting this instrument.

Product Description
Product Description
The 16048A consists of a direct attachment, 4-terminal pair type fixture which is
equipped with four BNC (m) terminated-coaxial test leads. These test leads are
used to attach user-fabricated test fixtures. DC bias levels of up to ±40V can be
applied to the 16048A. Cable length is 1 meter. The 16048A is shown in Figure
1-1.

Compensation for Fixture Residual Impedance Error
Compensation for Fixture Residual Impedance Error
The 16048A has inherent stray capacitance, residual inductance, and residual
resistance that affect the accuracy of measured values. To compensate for, or
negate, these residuals to minimize measurement error, the instrument’s
Open/Short compensation procedure should be performed. The procedure is given
in the instrument’s operating manual.
