Abstract

PURPOSE:To secure generation of the marker signal which is freely variable in a wide range of frequency with a high frequency accuracy, by providing a comparator to compare the count time with the standard time and producing the marker signal with the output of the comparator. CONSTITUTION:The frequency sweep is started (b) from gate signal T2 via the sweep signal oscillator, and preset counter 9 begins to count the sweep signals (500K Hz-1M Hz) which are supplied (2). While reference oscillator 11 delivers (b') 100musec. accurately via divider 12. Thus, the input sweep signal frequency of counter 9 becomes high gradually, and accordingly the time to count set value 60 (meaning 600K Hz) of frequency setting unit 10-1 is shortened gradually. When the counting time becomes (c') shorter than 100mus (sweep signal featuring 600K Hz), comparator 1 delivers the output to drive multivibator circuit 15 and then delivers the marker signal of 600K Hz. The marker signal is then counted (16) and advanced by one to switch frequency setting unit 10 via decoder 17. And numerical value 65 of unit 102 is set to counter 9.
