Seibersdorf Laboratories RefRad X Comb Generator and Field Source
Seibersdorf Laboratories RefRad X Comb Generator and Field Source with FiberLink X for Frequency Synchronization to increase the dynamic range by up to 30 dB
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.
Advantages
• 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
RefRad X 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 Frequency Spacing
· 10 kHz, 1 MHz, 5 MHz

RefRad X Comb Generator
The newly developed battery operated comb generator RefRad X is especially designed for checking the quality of radiated and conducted EMC and EMF tests. Initially introduced in the beginning of 2008, several modifications in the print design have enhanced the RefRad X considerably.
The RefRad X Comb Generator can be used to perform conducted measurements. When the antenna element is attached the device turns into the convenient, easy to use RefRad X Field Source for radiated system checks with no cables required. With the available FibreLink X an external synchronisation with the measurement receiver makes a small measuring bandwidth possible and improves the signal-to-noise ratio by up to 30dB. Thus it is a valuable tool for engineers to ensure the quality of EMC tests in the frequency range between 10 kHz up to 3 GHz and beyond.
A comb generator is built inside a conical antenna element. Therefore no cable between antenna and generator is necessary. This allows for repeatable measurement results and a reliable simulation of radiation performance.
Three switchable frequency settings are available:
· 10 kHz
· 1 MHz
· 5 MHz
