RefRad X Comb Generator

The improved battery-operated comb generator RefRad X with high precision internal oscillator, optimised housing, increased battery capacity and OLED display is especially designed for checking the quality of radiated and conducted EMC and EMF tests.

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. The highly accurate built-in oscillator (frequency stability ±20 ppb) can be tuned to match customers EMI receiver reference frequency (within ±5 ppb possible) to increase dynamic range and reduce measurement time. Due to this new calibration feature, no additional tool (e.g.: fibre link) is required anymore.

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.

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 and 5 MHz.
