R. C. Weir, K Ashcroft · Defense Technical Information Center (DTIC) · 1977
A DREP-designed Interface Unit is described that links a PEC Incremental Tape Transport with a GR 1921 Real-Time Analyzer. The Interface Unit supplies the timing and control for the system. Four sets of signals are sampled periodically, and the resulting tape record is later used with a Sigma-7 computer to yield plots of dB level versus frequency. (Author)
