This manual contains directions for use that apply to the Timer/Counter/Analyzers CNT-90 and CNT-91 as well as the Frequency Calibrator/Analyzer CNT-91R and CNT-91R/AF and the Mi­crowave Counter/Analyzer CNT-90XL.

  • CNT-90/91 means CNT-90 and CNT-91
  • CNT-91(R) means CNT-91, CNT-91R and CNT-91R/AF
