Immunity Testing Systems
CIS Series
The CIS series test systems are configured to perform conducted immunity testing according to IEC 61000-4-6. The system includes an ACS series power amplifier, coupling/decoupling Network (CDN), directional coupler, 150Ω to 50Ω adapters, power attenuators, cables and [optional] CSAT software. These systems, when properly configured, are capable of testing your products to all levels given in IEC 61000-4-6 up to 230 MHz. You can choose from three systems. Follow the links below for detailed information, including a comprehensive datasheet listing system specs.

CDNs
M Series
Coupling Decoupling Networks are recommenced for all power supplies connections. The distubance signals are coupled to each conductor in the supply lines according to EN 61000-4-6 standard. The standard M series CDNs have a current rating of 25 Amps. Com-Power CDNs are available for power supplies from 1 to 5 conductors. These CDNs cover the frequency range of 150 kHz - 230 MHz.

Horn Antennas
Horn antennas can be used for emissions and immunity testing. These antennas are constructed using light weight aluminum with a corrosion resistant conductive coating for indoor or outdoor use. Each antenna is individually calibrated. The calibration data and certificate will be shipped with each antenna.The high gain reduces input power requirements to generate high electromagnetic field levels for immunity testing. High gain also increases antenna sensitivity to low level signals.

Comb Generators
As an EMC testing lab, the accuracy of your results is key to your reputation. Maintaining this accuracy requires properly calibrated quality equipment. Comb generators are an important piece of EMC radiated emissions testing equipment - one that can save you time and money by reducing your reliance on full, annual recalibrations of your site and instrumentation.

Preamplifiers
Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification. EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.

Transient Limiters
Transient limiter LIT-153A and LIT-930A protects a spectrum analyzer input from high-level transients from the line impedance stabilization networks during EMC conducted emissions testing. It has a combined frequency range of 9 kHz to 30 MHz. The built in high pass filter helps reduce 50/60 Hz line feed through. (see application notes)

Dipole Antenna
AD-100
The Tuned Dipole Antenna model AD-100 is a reference antenna set specified in many EMC standards. It is used in the frequency range of 30 MHz to 1 GHz. This set consists of four baluns and was designed according to American National Standard C63.4. This reference antenna set is used for EMC test site calibrations and for calibrating other antennas, because it is considered a standard antenna according to ANSI C63.5 standard.

Emissions Test System
PC-114
Perform Radiated & Conducted EMI pre-compliance testing at your facility up to 1 GHz. Com-Power PC-114 EMI emissions test system is a ideal solution performing pre-compliance EMC testing from 9 kHz - 1 GHz.. It has essential equipment needed for radiated and conducted EMI emissions measurements. The system includes a spectrum analyzer, antennas, near field probes, a preamplifier, LISN and a non conductive antenna tripod. Pre-compliance testing in EMC is a commonly used term not easy to define. In general, it implies testing done prior to formal testing for legal compliance. Formal legal compliance is performed at a facility designed and equipped with test instrumentation that is fully compliant with the applicable EMC standards. Such facility and instrumentation is capital intensive and can be expensive even to rent and not easily available. Compliance testing is performed per exacting requirements of the Standards and other reference documents adhering to the test methods and last detail. In addition, the test facility may require to be accredited by an accreditation body such as NVLAP, A2LA. Often it is desirable to know prior to compliance testing at such facility, whether a product is close to compliance and also how close. Pre-compliance testing is specially useful for specifications such as FCC, Part 15, EN 55022 or EN 55011 (CISPR 22 or CISPR11). Pre-compliance testing usually means using the full compliance methods but making a few educated compromises in use of site or equipment to reduce costs and testing time. Here are some benefits of pre-compliance testing.
