Adjustment aid device of multichannel radio equipment

Abstract

Abstract PURPOSE:To facilitate operator's adjusting operation and to improve the operation efficiency by operating a PLL synthesizer part at a calculated intermediate transmission or reception frequency during transmission or reception in adjustment mode, and displaying the intermediate reception frequency or data on it on a display device. CONSTITUTION:When a mode changeover switch 26 is turned on, the intermediate frequency of an assigned reception frequency set in a ROM22 previously begins to be received automatically with a press-to-talk switch 27 off, and the intermediate frequency is displayed on a display part 24, so an adjusting operator easily sets the frequency of the equipment of a measurement system, e.g. standard signal generator over a look at the display. When the operator finishes adjusting the reception performance and turns on the press-to-talk switch 27, the intermediate frequency of the assigned transmission frequency set previously in the ROM22 begins to be received automatically and the intermediate frequency is displayed on the display part 24. Therefore, the adjusting operator easily sets the frequency of the measuring instrument system over a look at the display.
