CATHODE-RAY-TUBE SIGNAL ACTIVITY RECORDER

Abstract

A dark-trace CRT recorder was constructed which demonstrated the feasibility of a signal-activity recorder for use with microwave receivers such as the AN/APR-9, AN/BLR-1, and AN/SLR. A National Union NU-2112-E dark-trace tube was used for recording the video output from an AN/APR-9 receiver. Pulse- signal bursts as short as 1/30 sec were recorded while the receiver was continuously scanning in frequency. The record was clearly visible on a single scan; this permitted the setting of the receiver frequency to the signal record and insured a high probability of reception on succeeding bursts. The physical problems encountered in the NU-2112-E park-trace tube indicated the need for considerable improvement in tube characteristics before this type of recorder can be considered for field applications.
