Scan-lock control of solid state digitally synthesized receivers |
摘要 |
A scan-lock control device is provided for use with a high frequency receiver in a manner which adds frequency scanning and lock-up functions to the receiver without affecting any of the receiver's other functions. The scan-lock control incorporates an interface unit which can be operatively connected to the receiver to interconnect scanning and lock-up circuits to the receiver. The scan-lock device also incorporates a novel multiplexer unit which is modular and expandable and has a plurality of plug-in cards operatively associated therewith; each card having programmed thereon a frequency data channel which may be selectively scanned.
