3. Frequency, DC Bias, and Operating Temperature/Humidity

Each of the Agilent accessories has its own specific operating range. Any measurement performed out-

side this range can increase residual errors and can cause problems. Be sure that your measurement

environment fits the accessory’s specific operating range. In the case of humidity, Agilent’s accessories

can operate at a relative humidity of 95% or less at 40°C. (These same requirements apply to most LCR

Meters and Impedance Analyzers.) When the ambient temperature is not approximately 40°C, use an

accessory that has no condensation on its surface.

4. DUT (Device Under Test) Dimensions

The DUT can vary from chip components, axial/radial leads, or ICs to general electrical devices. Select a

test fixture/lead that is suitable for the shape and size of your components or materials.

5. Open & Short Repeatability and Proportional Error

Since a test fixture induces an additional error when measuring, the total measurement error is the sum

of the measurement instrument’s measurement accuracy and the fixture’s additional error. Generally, a

test fixture’s additional error consists of three terms: open repeatability, short repeatability and propor-

tional error. Open and short repeatability exhibit the error factors of the open and short residual imped-

ances which affect the measurements of extremely high and low impedances respectively. Proportional

error exhibits the error factor, which is proportional to the size of the impedance being measured. For

more details on this subject, please see the Appendix.

6. Furnished Accessories

Each test fixture is shipped with a manual and various other accessories needed for measuring. For

example, the 42941A impedance probe kit is furnished with a pin probe, an adapter (BNC-SMB), 3 spare

pins, a carrying case and an operation and service manual.
