CIT-1000

Conducted RF-immunity testing and BCI-testing acc. to IEC/EN 61000-4-6, ISO 11452-4, MIL-STD 461, CS114 and similar standards

The CIT-1000 is a further development of the for years available and proven „CIT-10“, 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 our CIT-series, all integrated instruments, like Signalgenerator, RF-Power-Amplifier and the 3-channel-RF Power Meter can be used as „stand-alone-unit“, too.

Hence, the Signal-generator and the RF-power-meter can also be used for radiated immunity tests acc. IEC/EN 61000-4-3. Furthermore an additional external RF-Power-amplifier could be connected to the CIT-1000 for this purpose.
