CIT-100
Conducted RF-immunity testing and BCI-testing acc. to IEC/EN 61000-4-6, ISO 11452-4, MIL-STD 461, CS114 and similar standards
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-100 is a complete test system for 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 system coconsists of a built-in
• Signal generator, 4kHz – 1.2 GHz
• RF-Power-Amplifier. max 4kHz – 400 MHz, 25 / 75 W
• 3-Channel RF-Power-Meter to measure the test level as well as forward & reverse power, 4kHz – 1.2 GHz
• Directional Coupler
• Comfortable control software
As a „stand-alone“ test system the CIT-100 is convincing by its easy and comfortable handling and the excellent cost-performance ratio.
We also offer the full range of coupling/decoupling networks (CDN‘s) ,
EM-coupling clamp, BCI- and current clamps.
Special Features
Conducted RF immunity tests acc. to IEC/EN61000-4-6 and BCI tests acc. to ISO 11452-4 and MIL-STD 461 CS 114
Signalgenerator,RF-power amplifier, RF-power meter and directional coupler in one 19”-case
All built in instruments can also be used separately, via existing input / output connector.
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-100 for this purpose.
Stand-alone operation possible with optional available netbook
Control-software included
Most important parameters are shown on an integrated display
Automatic EUT-monitoring
Complete range of CDNs available
Features
Internal RF-Power Amplifier
Several amplifier modules are available. Highest output power can be 75 W over the specified frequency range. The amplifier input can be accessed via the back panel of the CIT-100, so that the amplifier can also be used with any external generator. 25 W and 75 W amplifiers are available as standard.
Amplitude Modulation
Frequencies generated by the generator can also be modulated with a LF signal. Modulation frequencies may vary from 1 Hz up to 100 kHz, modulation levels are available from 0 % to 100 %.
Internal RF-Voltmeter
Accurate measurements of RF signals from -40 dBm up to +30 dBm are done by the internal RF-voltmeter which can be accessed (for separate use) via a BNC connector. Two internal voltmeters measure the test level and two channels to measure the forward and reverse power via the built-in directional coupler.
Internal RF-Signal Generator
As the internal generator generates its output signal without any internal mixing components, low harmonics and spurious frequencies are assured.
User defined signals
External signals (e.g. EUT-fail or external instruments) can be connected and monitored using the application software.
