Contact Check E Ective Range; Relation Between C; And Cable Capacitance Cig - Agilent Technologies 4349B Manual

Contact Check E ective Range
Available DUT type: Capacitive DUT only
Contact check e ective range: The DUT's capacitance Cd must meets the following equation.
where, C is the capacitance value obtained by
x
command when the test cable/test xture is connected to the 4349B.
Figure 8-10. Relation Between C
The cable capacitance Cig shows the capacitance between the center condictor and the
inner shield of the triaxial cable. The 16117E's capacitance is about 40 pF/meter. The cable
capacitance is in proportion to the cable length.
The following is the sample program to obtain Cres of each channel. It is necessary to perform
the OPEN correction before reading Cres.
