SDR-54A Satellite Demodulator Revision 4
Installation MN/SDR54A.IOM
Demodulation frequency, rate, and reacquisition time are defined as follows:
Term Definition
Frequency Carrier frequency of the desired channel
Rate Data rate of the desired channel
Reacquisition Time Time delay from incidental carrier loss until the modem initiates
carrier search
Note: The above values, when set, are retained by the demodulator until changed by the
user. Once the demodulator is configured and operating, the terminal is no longer
required.
Once configured, the demodulator will perform an acquisition search for the desired
channel. If a signal is present at a sufficient level, the CARRIER DETECT indicator on
the front panel will illuminate. Data will be present at the DATA OUT serial port, if the
detected signal can be demodulated and decoded.
