DEVICE FOR DIAGNOSING RADIO COMMUNICATION FACILITIES AND AFFORDING THEIR SERVICEABILITY

摘要

FIELD: radio engineering. ^ SUBSTANCE: device designed to anticipate trouble in receiving module and to switch radio equipment over to stand-by facility in due time has two similar step-down converters, each incorporating first and second amplifiers, adjustable attenuator, first and second mixers, band filter, and automatic gain control (AGC). Device also has transceiver control board incorporating AGC recording circuit, switching unit, analog-to-digital converter, probabilistic prediction unit, and electronically reprogrammable random-access memory. ^ EFFECT: enhanced operating reliability of radio equipment inspected and prepared for operation by this device. ^ 1 cl, 3 dwg
