This high performance test loop translator is intended for use in professional applications in Ku band such as satellite earth stations. This device covers and supports the most commonly used frequency bands in the Ku range of the spectrum. BMCD101 is a professional test device to check the transmission performance of a ground station without actual satellite connection. Low phase noise parameter and clear spectrum, which is free from unwanted spurious and other phenomena, help to evaluate the RF system performance. All key parameters can be controlled and monitored through a user interface via RS-422 and Ethernet.
