Introduction：
BBV 9743 B is a general-purpose broadband preamplifier produced by Schwarzbeck, Germany and authorized by Shenzhen EUTTEST agent for sale, 9743B amplifier has the advantages of high gain of 28dB and very low internal noise, so this amplifier can be directly connected to the EMI test antenna and EMI test receiver, in order to measure the very low EMI limit line, you may need to reduce the detector setting value, of course, you should first set the appropriate size of the QP and AV detector according to the test requirements. In order to measure very low EMI limit lines, you may need to lower the detector settings, but of course you should first set the appropriate QP and AV detector sizes according to your test requirements.
