EFData SDM-2020 Satellite Demodulator



SDM-2020 Satellite Demodulator manufactured by EFData, later to be merged with Comtech. At the time that these products were manufactured EFData manufactured two separate items, one was the SDM-2020M, this is the modulator, and to match this they built an SDM-2020D the demodulator.

SDM-2020 Satellite Demodulator

This particular unit has 8PSK, 16QAM and Reed Solomon.

Here is a sample from the SDM2020D datasheet

• Digital Video Broadcast (DVB)
• Transparent Data Transmission
• Programmable 1.5 to 100 Mbit/s
• 8PSK and 16QAM (Optional)
• L-Band input 1 (Standard), 2 or 4 Optional
