RefRad Comb Generators

RadRad is a battery operated comb generator as well as a field source.It is a valuable tool for engineers ensuring the quality of radiated and conducted EMC and EMF measurements.



  • Ensures reliable measurement results
  • Avoids costly retesting by detecting defective measurement instruments prior to testing
  • Guarantees fulfilment of ISO 17025 requirement for the regular check of test equipment

A comb generator is built inside a conical antenna element. Therefore no cable between antenna and generator is required. Thus leads to repeatable measurement results and reliable simulation of radiation performance. A fibre link for synchronisation with the receiver is used.


Frequency Range 10 kHz - 3 GHz
