3. Coupling test;
4.RF function of the relevant tests, such as the transmitter radiation power test, the receiver sensitivity test; Detection equipment: network analyzers, signal generators, spectrum analyzers, dipole antenna, horn antenna, shieldingbox, and so on.
5.Other communications technology tests: GSM，WCDMA，WiMAX，LTE，GNSS，Bluetooth，WIFI、Zigbee、NB-IOT、5G,etc. Reference Documents For the Calibration：GB/T 12190-2006 Method for measuring the shielding effectiveness of
Electromagnetic shielding enclosures
OTA Non-signaling Coupling Test System
Production test box is a new generation of production line OTA test equipment, which can replace the traditional production line coupling test box, and can support up to 4 wireless products at the same time parallel test, It is used to do non-signaling OTA test of production line, providing unprecedented fast test time and very high measurement accuracy and repeatability.
Antenna Couple:
Antenna couple has two types of frequency: 3G (80mhz~2650mhz) and 6G(800mhz~8000mhz), which cover the current wireless test frequency range :
(1) Reproducible consistency measurement.
(2) To realize the measurement of radiation mode
Soundpoof-Box/Acoustic Chamber/ Anechoic Box Product Application:
Widely used in a variety of audio testing and improve the test environment, the sound box products can do the background noise25db~30db. We Secretary for many years through the accumulation of technology and the constant attempt of various materials, independent research and development, testing, production specifications, the shielding effect of the shielding box / room. We provide a steady testing environment with noise floor low as 30dBA for performance testing of acoustic products, such as speaker, receiver and mic. Sound isolation can reach more than 40dB(300Hz~20kHz), Also, we can customize sound-isolated box with special size and fixture, and provide integrated testing system solutions.
