Dipole test probes and RF test probes are used in various industries: They enable precise, accurately repeatable measurement of resistance as well as RF performance.

Using dipole test probes, 4-wire measurements to accurately determine resistances can be performed. In doing so, the voltage is measured using the inner conductor and the current is measured using the outer conductor.

RF test probes are used to contact plug connectors, mini switches and PCB test points. These are used in the following way:

Plug connectors are used to connect a variety of RF components, such as cables and PCB modules. In the automotive industry, plug connectors such as FAKRA or HSD connectors are used to transmit audio and video signals. U.FL connectors are used in radio modules, among others.

Mini switches are used to test RF signals which are supplied by chip antennas or PCB antennas.

PCB test points alow RF signals to be contacted directly on to the PC board. Depending on the nature of the PC board and application, this is carried out in various ways.

The dipole test probes developed by INGUN are highly suitable for performing 4-wire measurements thanks to their coaxial design. This allows the voltage to be measured directly on the contact surface and the resistance to be determined. Furthermore, it is also possible to perform connection tests on coaxial plug connectors. 
Depending on the application, variable grid sizes, tip styles and dimensions are available.
Dipole test probes are installed using a receptacle. The connection is made using

To optimally fulfill the requirements in radio frequency testing, various versions of the RF test probes are available.
Selection criteria for choosing a suitable RF test probe include the test point to be contacted, the frequency or data rate, the installation area (the space available for probe installation) as well as the ambient conditions.
