EFA 60/63 characteristics

Fully compatible with the DVB-C standard (EN 300 429), the EFA 60/63 models receive, demodulate, decode and analyze all orders of QAM (quadrature amplitude modulated) signals. All key parameters for demodulating the received signal can be automatically or manually selected:

• 4, 16, 32, 64, 128 or 256 QAM modulation
• Variable symbol rate for special modulator tests and lab analysis (1 Msymbol/s to 6.999 Msymbol/s)
• Reed-Solomon error correction
• Optional SAW filter bandwidths: 6 MHz, 7 MHz, 8 MHz and 2 MHz
• Input of any IF frequency with the aid of the EFA-B3 option: frequency range continuously tunable from 5 MHz to 1000 MHz
• Special function: invert spectrum
• Bit error ratio measurement (before and after Reed-Solomon decoder)
• Integrated noise generator for measurement of noise margin
