HFS test probes

HFS Radio-frequency Test Probes

Radio-frequency Test Probes are mainly used for measuring high-frequency signals (up to 6 GHz.). These Test Probes are designed co-axially, i.e. the measurement signals flow via the inner conductor and  the outer conductor is used for the shielding of the signals. For the connection to the Test System the applicable co-axial cables are available.

Application Examples:

  • Sensitive measurement tasks with high  measurement frequencies
  • 4-pole measurements
  • Contacting of common RF-Plugs and RF-Jacks
  • Contacting of RF Test Points on PC-Boards
  • Available in non-rotating version with a cut-out on the  GND-Tip (i.e. for when the signal track on the  PC-Board has been laid out accordingly)


  • Very good measurement reliability
  • Compact and stable design
  • Modular design for flexible exchange of individual components (Note: in the series HFS-810 the inner and  outer conductors are interchangeable)
  • Large variety of different tip-styles for various RF-Plugs  and RF–Jack
