RefRad 18 Reference Radiator
The RefRad18 is an innovative reference radiator with an integrated directional antenna for the frequency range 1 – 18 GHz. Via coaxial output it can be used for conducted measurements. Its OLED display and user-friendly interface ensure easy operation, making it an ideal choice for engineers.
Unique Features
Compared to conventional comb generators, the innovative signal generation design of the RefRad 18 offers several advantages:
- Higher output power
- Flat frequency response (coaxial output)
- Two levels (HI/LO) for field strength measurements and coaxial applications
- Excellent frequency stability due to temperature compensation
- Frequency range 1 – 6 GHz or 1 – 18 GHz selectable
- battery-operated (Li-Ion) and chargeable via USB-C
- accredited calibration included
The new concept of the RefRad 18 requires a different measurement method compared to a traditional comb generator. The synthesizer generates a signal every 50 MHz (1 - 4 GHz), 100 MHz (4 – 8 GHz) and 200 MHz (8 – 18 GHz). The minimum measurement time per frequency is 500 µs and therefore the whole sweep 1 – 18 GHz can be done in 11.4 seconds. For EMI Receivers, proper setting of bandwidths and measurement time is essential to ensure accurate measurements. Spectrum analysers must be operated at zero span. Compatible with the most common programmes for measuring electromagnetic interference and CalStan 11 - of course .
Please refer to the Operating Principle for more information on this measurement method.
