RF-and dipole test probes are used in various industries: They enable a precise, accurately repeatable measurement of RF performance, as well as resistance.
RF test probes
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.
RF test probes are used to contact plug connectors, mini switches and PCB test points. These are used in the following way:
Dipole test probes
- 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 are structures upon which RF signals can 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 either a connector or by soldering on the receptacle.
