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.

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.

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.

Combilog Antenna
AC-220
-
The AC-220 Combilog antenna is for EMC emission and immunity up to 2 GHz.. It combines the electrical properties of two antenna (biconical and Log ). It reduces overall testing time by 20 - 30% due to antenna switching. It is Optimized for emission measurements, but can handle up to 500 Watt CW, making it suitable for most immunity measurements . Each antenna is individually calibrated at 10 meters and the data included the purchase price.

Active Loop Antenna
AL-130R
-
Also known as Magnetic Loop Antenna, the AL-130R is compliant with CISPR 16-1-4. It is ideal for emissions measurements as required by various EMC standards such as FCC 18, CISPR 11, CISPR 13, CISPR 14, CISPR 32 and many more. The built-in, low-noise preamplifier, increases overall measurement sensitivity as well as the overall signal to noise ratio. As per ANSI C63.4-2014, the use of active loop antenna for compliance testing is permitted in a non-sheilded environment ONLY if the saturation indicator is continuously monitored during the course of testing. Com-Power’s Remote Antenna Interface (RAI-100) comes in very handy for this application. It is a compact controller which can be used to enable/ disable RF measurement circuit and monitor saturation and battery low conditions remotely via a fiber optic cable up to 30 mtrs in length.

Biconical Antennas
-
Biconical antennas are used for emissions and immunity testing to meet various EMC standards specified by FCC, CISPR and EN. The broadband characteristics of the biconical antenna make it a good choice for making sweep measurements and for automated measurement systems.

Active Monopole Antenna
AM-741
-
The 41 inch Monopole antenna is required for making electric field emission measurements below 60 MHz per Military standards (MIL-STD-461) and FAA (DO-160) specifications. This antenna is for emissions measurements only. It cannot be used for transmitting. The Active Monopole antenna is generally used in a shielded room or in a screen room, with the equipment under test (EUT) placed on a metal ground plane. The 41 inch rod and the ground plane behave electrically as though a mirror image of the rod were located below the ground, and the ground removed. Since the stainless steel plate does not have enough surface area to mirror the entire 41 inch rod, it is bonded to the surrounding ground plane during use. The AM-741 is battery powered to prevent measurement errors that maybe caused by external power cables. The ANSI equivalent capacitance substitution (ECSM) method is the recommended method for calibrating AM-741 monopole antenna. The individual calibration data will be included with each antenna.

Near Field Probes
-
A typical emi emission test is performed using broadband EMC antennas such as biconical, log periodics, Combilogs and horns. These antennas usually placed at 1, 3 or 10 meter distance as required by the test specification. These is considered far field measurements and the emission limits are given for the specific distance by the specification. During EMI compliance measurements, the emissions levels from products are compared with these limits. If the product exceeds these limits it is considered failing. These tests are typically conducted in a open area test site IOATS) or inside an anechoic chamber.
