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 ±42V 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.
