Electrical Length Compensation

The electrical lengths of the test fixtures shown below have been registered in the E4991B in advance. To use these fixtures, you may set the needed electrical length by simply selecting the model number of the fixture to be used. If you use fixtures that are not registered, however, you must enter the electrical length as a numerical value.

Model Number	Electrical Length
16191A	14 mm
16192A	11 mm
16193A	14 mm
16194A	50 mm
16196A	26.2 mm
16196B	26.9 mm
16196C	27.1 mm
16196D	27.3 mm
16197A	14 mm
16198A	N/A
16453A	0 mm
16454A (Fixture size: S)	0 mm
16454A (Fixture size: L)	0 mm

The electrical length compensation is not applied to the 16198A. The 16198A is compensated by the other technique.

The 16453A is automatically selected when the permittivity measurement (Permittivity) is selected as material type (Material Type). The 16454A (fixture size: S) or 16454A (fixture size: L) can be selected when the permeability measurement (Permeability) is selected as material type (Material Type). For selecting the material type, refer to Setting Material Measurement Parameter (Option 002 Only).

Procedure

Press Cal > Accessory > select the fixture model number. To select a test fixture that is not registered, select Arbitrary.
If Arbitrary is selected, press Cal > Accessory Length > enter the fixture length.
