Key Facts
EFA 20/23 characteristics
Fully compatible with the DVB-C standard (EN 300 429), the EFA 20/23 models receive, demodulate, decode and analyze all orders of QAM (quadrature amplitude modulated) signals. All key parameters for demodulating the received signal can be selected automatically or manually.
