RF Conducted Immunity Test System – IEC 61000-4-6




The CIT-100 is a complete test system for conducted RF-immunity tests according to IEC 61000-4-6, ISO 11452-4, MIL-STD-461 – CS114 and similar standards. Its internal signal generator and RF power amplifier produce output signals up to 75 W within a frequency range from 4 kHz up to 1.2 GHz. Test level, forward and reverse power are measured by 3 internal RF power meters via the built-in directional coupler. The whole test system allows fully automatic tests for the specified frequency range. As a stand-alone test system the CIT-100 is easy to use and has an excellent cost-performance ratio. Add-ons such as coupling/decoupling devices, EM clamps and bulk current injection probes are available as well.

Applicable Standards:

  • IEC 61000-4-6
  • MIL-STD-461 CS114
  • ISO 11452-4
  • SAE-J1113-2
  • DC 10614

The CIT-100 is PC-controlled. It can be operated by any commercial PC (Microsoft® Windows software) via USB port. All equipment settings, e.g. start frequency, stop frequency, step width, test voltage etc. are made through the control software which is included in the delivery. The three functional units RF-signal generator, RF-power amplifier and RF-voltmeter are set automatically by the software, depending on the pre-set test parameters. Each component, however, may also be operated as a separate measuring and testing equipment. This means the user has 3 full, additional “single units” at their disposal for which separate inputs and outputs are available as BNC connections. Due to the computer-aided control of the CIT-100, any modifications which may become necessary, due to revision of standards, may be performed easily without having to manipulate the hardware of the equipment.



The CIT-1000 is a further development of the proven CIT-100, with the extended frequency range up to 1200MHz, stand-alone-operation via integrated Touch-Screen-PC as well as integrated directional coupler and power meter for forward and reverse power measurement. As usual with the CIT-series, all integrated instruments, like signal generator, RF power amplifier and the 3-channel-RF power meter can be used as stand alone instruments as well. Therefore the signal generator and the RF power meter can also be used for radiated immunity tests according to IEC 61000-4-3. Furthermore an additional external RF-Power-amplifier could be connected to the CIT-1000 for this purpose.
