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

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

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.
