The Agilent 4294A is a powerful tool for

design, qualification, quality control,

and production testing of electronic

components. Circuit designers and

developers can also benefit from the

performance/functionality offered.

Moreover, the 4294A’s high measure-

ment performance and capable

functionality delivers a powerful tool

to circuit design and development

as well as materials research and

development (both electronic and

non-electronic materials) environments.

The following are application examples:

Electronic devices

Passive component

• Impedance measurement of two

terminal components such as

capacitors, inductors, ferrite beads,

resistors, transformers, crystal/

ceramic resonators, multi-chip

modules or array/network

components.

Semiconductor components

• C-V characteristic analysis of

varactor diodes.

• Parasitic analysis of a diode, tran-

sistor, or IC package terminal/leads.

• Amplifier input/output impedance

measurement.

Other components

• Impedance evaluation of printed

circuit boards, relays, switches,

cables, batteries, etc.

Materials

Dielectric material

• Permittivity and loss tangent evalu-

ation of plastics, ceramics, printed

circuit boards, and other dielectric

materials.

Magnetic material

• Permeability and loss tangent eval-

uation of ferrite, amorphous, and

other magnetic materials.

Semiconductor material

Permittivity, conductivity, and C-V

characterization of semiconductor

materials.
