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
  • Highly accurate built-in oscillator (frequency stability ±20 ppb)
  • Individual accredited calibration certificate included

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.

Frequency Range:    10 kHz - 3 GHz
Frequency Spacing:  10 kHz, 1 MHz, 5 MHz
