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.

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.

Setup

The CIT-10 is a PC-controlled test equipment. It can be operated by any commercial IBM compatible PC (Microsoft® Windows software) via USB port. All settings of the equipment, e.g. start frequency, stop frequency,
step width, test voltage etc. are made by means of the control software which is also 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 called and operated as separate measuring and testing equipment. This means: using the CIT-10 as testing system, you have three full, additional “single units” at your disposal, for which separate inputs and outputs are available as BNC connections. Due to the computer-aided control of the CIT-10, any modifications which may become necessary, for example, due to the revision of standards, may be performed without problems and without having to manipulate the hardware of the equipment.
