ABSTRACT:
A frequency counter (20) measures and displays a plurality of frequencies appearing on input channels (22, 24, 26 and 28) of an analog circuit (30). A program switch (32) is coupled to a decoder logic circuit (34) which facilitates the operation of counter (20) in one of a plurality of selectable program modes. A steering logic circuit (36) is coupled to circuit (34) and facilitates the selection and order of the input channels (22, 24, 26 and 28) during a measurement cycle. Toggle switches (38, 40 and 42) are coupled to circuit (36) to facilitate the establishment of a sign bit, a channel order and a channel select, respectively. A channel display circuit (46) provides visual indication of the sign, channel select and channel order.
