The HP office will arrange for repair or replacement without waiting for claim settle- ment. Meas- ured sample values include 44275a which vary such values because of electromagnetic effects such as the well-known skin effect of a conductor, the general characteristics of ferromagnetic inductor cores, and effects of dielectric materials in capacitors.
Most significant- ly, the A can be of particular help in the experimental assessment of devices in the semiconductor testing field. Test signal level mo nitor: Use contact module for short lead components or the C Test Fixture designed especially for high frequency measurements.
On the other hand, for a high capacitance sample such as an electroly- tic capacitor, the equivalent series resist- ance consisting of lead resistance, electrode resistance, dielectric loss, etc. Useable on all A ranges. When test cables are used in high frequency measurements, the displayed test voltage may have lesser accuracy. The three numeral combinations in the tables indicate the numbers of digits displayed in the respective range and test fre- quency areas.
The typical accuracies at frequen- cies above IMHz given in the table apply when a direct attachment type test fixture is used.
The second method is to connect a capacitor and inductor to the device under test, as shown below.

Accuracies apply under the following measurement conditions for all test parameters: An appropriate offset compensation quantity is automatically calculated everytime a meas- urement is taken. The effective resist- ance increases at resonance even if the in- ductor has ideally no resistance at dc. To construct this terminal architecture, connection of a sample to the instrument requires the use of a test fixture or test leads in a four terminal pair configuration design.
The A Option provides a manuql by battery for maintaining the volatile 4275q in event the instrument loses power.
Typical Impedance Locus of an Inductor Measurement readings of an inductor may thus differ widely depending on the test level and test frequency. What are the major reasons for these changes in sample values?
By using a string variable complete output information from the A OptJOl is stored by the following program: A terminal marked with this symbol must be connected to ground in the manner described in the installation operating manual, and before operating the equipment. An initial function test is automatically performed before measurement begins.
Rack flange kit, for mount- ing in lEC standard rack. When this function is set to AUTO, the Instru- ment automatically selects 42775a priate parallel or series equivalent circuit.
Option Installation 3- 0. The extra display section of the A pro- vides for a display of the test frequency setting, test signal voltage, or current ap- plied to DUT in 3 digits.
The reference value is obtained and memorized from the preceding 42275a. Install connector board assembly Offset adjustment ranges are: Error in ranging operation. Thus, the A is a truly versatile instrument which can re- spond to the diverse measurement requirements in research, circuit design, production test- ing and the QA inspection areas. Actually, a measurement can be taken if a certain magnitude of impedance larger than that of the unknown sample is present between the grounding point of the sample and instrument ground.
