IS 14189 : 1994 Expression of the properties of frequency counters (Upto a frequency of 1 GHz) - Doc: LTD 21(1121)F

1 Scope

1.1 This standard is applicable to instruments known asfrequency counters to measure time related properties of arepetitive signal available in electrical form, hear after called`input signal', at its inputs.

1.2 As the fundamental property these instruments measurefrequency of a signal by direct or prescaled counting process anddisplay the measured value in digital form on their displays.

1.3 In addition these instruments may have facilities to measuretime period, time interval, ratio of two frequencies and eventcounting.

Note - This standard is applicable to frequency counters up to afrequency of 1 GHz and does not apply to frequency counters whichuse the technique of reciprocal counting or super-heterodyningprinciple.
