MITEQ’s Model RCV-INMST Inmarsat pilot receiver, available from Electronic Development Sales , makes use of digital signal processing techniques to track a CW pilot signal.
A phase continuous, 1Hz step size, frequency synthesizer generates an error correction signal which is used in conjuction with Miteq's Inmarsat AFC capable frequency converters to provide automatic frequency control for both maritime and aeronautical (enhanced AFC) applications.
· Enhanced AFC operation.
· Low noise/low spurious output.
· Tunable input (5kHz step size).
· Extensive remote capability (RS485).
· Large graphic display and simple setup.
Options available include higher output level; 50 ohm IF impedence; 10 MHz reference frequency; remote RS422, RS232, or IEEE-488 interface.
