Introduction：
USLP 9143 is a logarithmic periodic antenna developed and manufactured by Schwarzbeck, Germany, and authorized to be sold by EUTTEST in Shenzhen, China. The antenna's transverse size is only 550m, but the test frequency range can be applied up to 8GHz, and it can be used in most of the EMC test standards and test applications, such as the CISPR25 and other standards.
The antenna's VSWR is <2 over the test bandwidth, reducing the reflection of the log-periodic antenna from the transmitter port, and you only need to purchase the RF cables supplied by EUTTEST together for low-loss radiated emissions and radiated immunity testing.
Installation method:
The antenna can be mounted on the AM9144 antenna tripod using the antenna adapter as shown in the dimensions below.
Installation Dimension Drawing
Then enter the power or antenna coefficients in the EMC test software, and then you can start the test. Our company will provide the integration service for the purchasing customer to install the logarithmic cycle antenna test system at home.
Differences and similarities between antennas 9143B and 9143:
The following table is a comparison table of the parameters of two similar antenna models, please select the appropriate antenna for EMC test according to the test requirements.
