PURPOSE:To display the resolution at the current time point in a frequency counting part, by displaying the output of a resolution memory where the precision of the resolution of the frequency counting part is stored. CONSTITUTION:In case of the measurement for the frequency of a radiated radio wave of a radio station, when a switching part 3 is set to the resolution set mode by a mode changeover switch 9 and the resolution for frequency measurement is designated by a resolution selecting switch 7, the resolution stored in a resolution memory 2 is displayed on resolution indicators 6 of a display part 4. Next, when the switching part 3 is switched to the frequency measurement mode by the mode changeover switch 9, the frequency of a signal to be measured which is counted in a frequency counting part 1 is displayed on the display part 4. In this case, the resolution for frequency measurement in the frequcency counting part 1 is within digits where resoution indicators 6 are lit. |
