CISPR16-1-1 Gigahertz Transverse Electro Magnetic Cell EMI Test System

Product Specification

CISPR16-1-1 Gigahertz Transverse Electro Magnetic Cell EMI Test System

Product Overview For EMI Test System:

1. EMI Conducted Magnetic Disturbance Test System

This system mainly measures the interference caused by the equipment under test (EUT) to the surrounding environment through the power line (conducted disturbance) or in the form of space radiation (electric field radiation disturbance) under normal working conditions. The system is mainly composed of EMI test receiver, artificial power network (LISN), radiation receiving antenna, and special test software, which fully complies with the requirements of CISPR, FCC, MITL, GB and other relevant standards.

2. Radiated Emission Testing System

Using GTEM (Gigahertz Transverse Electromagnetic Wave) for electromagnetic compatibility testing is a new measurement technology developed in the field of international electromagnetic compatibility in recent years. Due to the broadband characteristics of GTEM (from direct current to microwave), low cost (only a few percent of the cost of the anechoic chamber), it can be used for both electromagnetic radiation test (EMI test) and electromagnetic radiation sensitivity test (EMS test sometimes also known as immunity test). Moreover, the instrument used (compared to the experiment in the anechoic chamber) has the characteristics of simple configuration, low cost and quick and automatic testing, so it has attracted more and more attention from international and domestic relevant people. Among them, especially for the testing of small equipment, the measurement solution of the GTEM cell is the test solution with the best performance-price ratio.

Product Features For EMI Test System:

1. PMM 7010 is an all-digital integrated EMI measurement receiver developed to meet the needs of product designers to perform massive EMC evaluation and measurement in the trial production stage.

2. Disturbance measurement in compliance with certification standards

3. For the civil standard test, the PMM 7010 weighted detector not only includes CISPR-Avarage and RMS-Avarage specified in CISPR16-1-1, but also has a unique APD detector (amplitude probability distribution test detector). The detector is used to evaluate the impact of electromagnetic interference above 1GHz on digital communication systems.

4. The APD measurement function defined in CISPR16-1-1

5. It has a variety of standard and optional test accessories, and has touch control and linkage functions to facilitate the accurate execution of the test content required by the standard.

6. It is used to Real-time spectrum analysis for in-depth analysis of disturbance details: PMM 7010 combined with powerful PMM Emission Suite can help people discover and measure electromagnetic disturbance spectrum caused by occasional or short-lived events. Identify intermittent interference from the frequency domain and time domain to speed up the progress of product certification.

7. Strong and durable, compact structure, suitable for on-site or field test applications: due to its small size, light weight (only 4.1kg including battery), built-in lithium battery power supply and other characteristics

8. In addition, PMM 7010 solves the problem of field electromagnetic interference testing for environmental assessment engineers, and develops matching antennas for China's high-level power transmission and transformation systems. It meets the test requirements of the existing 750kV and future 1000kV ultra-high voltage power transmission and transformation projects.

9. No calibration or maintenance required.
