PURPOSE:To produce a device for adjustment and inspection of a radar device compactly and inexpensively with a simple circuit constitution, by providing a clock generating part controlling circuit, a counter group, a presettable counter, a selector, and a decoder. CONSTITUTION:A clock generating part controlling circuit 1, plural counter groups which are controlled by the clock signal from the circuit 1, and presettable counters 5 (5a and 5b) are provided. Selectors 4 (4a and 4b), which select optionally counters 2 (2-1-a-2-n-b) of these counter groups and preset outputs of selected counters to presettable counters 5, and decoders 6 (6a and 6b) connected to the output side of presettable counters 5 are provided. Output signals of decoders 6 are synchronized with said clock signals inputted to presettable counters 5 and are changed in operation directions of counters 2 selected by selectors 4. |
