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.
