Comtech EFData SDM-9000 Satellite Equipment Modem
Comtech EFData SDM-9000 Satellite Equipment Modem is a very sophisticated SCPC satellite modem and although several years old, the first one that we put on the test bench worked perfectly.

Comtech EFData SDM-9000 Satellite Equipment Modem FEATURES
• IDR
• Fiber Restoral
• 6 Mbit/s to 52 Mbit/s
The SDM-9000 satellite modem is a high-performance, full- duplex, digital vector modulator/demodulator designed for IDR applications from 6 to 52 Mbit/s. When equipped with a G.703 interface and ESC overhead framing unit, the SDM-9000 meets all requirements for IESS-308 specifications.
This particular 52 Mbits/s modem appears to be fully loaded with 16QAM and Reed Solomon, all enabled.
What we like most about Comtech EFData products is that they have adopted a very similar front panel menu system over the years. If you are familiar with the current series of VSAT modems then configuring the Comtech EFData SDM-9000 Satellite Modem is a simple process.
Standard SCPC modems most often use the frequency range of 70MHz ± 18 MHz, Whereas the SDM-9000 has an operating frequency range of 50 to 180 MHz in 2.5 kHz steps.
