Setting Measurement Conditions

Set Measurement Parameter

The measurement mode (Impedance/Magnetic/Dielectric measurement) and the display

trace type (Scalar/Complex trace) determine the parameters available. The following

section explains how to set the measurement parameters.

Measurement Mode

Selection

When material measurement is performed by using the E4991A with option 002 (Material

Measurement), use the following GPIB command to set the measurement mode to

magnetic measurement or dielectric measurement. The E4991A without Option 002 sets

the measurement mode to impedance.

Parameters for Material Measurement

Before dielectric material measurement can be performed, the following GPIB command

must be used to set the thickness of the device under test.

• CALC:FORM:PAR:DIE on page 300

Before magnetic material measurement can be performed, the following GPIB command

must be used to set the sizes (inner and outer diameters and height) of the device under test.

Display Trace

The E4991A allows the user to display up to five traces. Use the following GPIB command

to display a trace.

• DISP:TRAC{1-5} on page 356

Of the five traces, Traces 1-3 are for scalar traces and Traces 4 -5 are for complex traces.
