PURPOSE:To make the measurement performed easily even by beginners by receiving various signals from a standard signal generator and selecting and displaying needed signals under the control by a program oscilloscope and CPU. CONSTITUTION:A signal from a distributor 3 of a standard signal source 1 is supplied to selector units 5a and 5b of measurement devices 4a and 4b. Objects to be measured, 6a and 6b, such as TV camera, etc. have their adjusting points connected with measurement terminals, and the outputs of those terminals are supplied to probe units 7a and 7b. The outputs from selector units 5a and 5b and probe change-over units 7a and 7b are made signal in a specified range by means of filter change-over units 8a and 8b and they are supplied to two input terminals 9a and 9b of a program oscilloscope and displayed to be compared there. In a control system, the instructions from CPU 10 are conveyed to units 5, 7, 8, etc. through I/O system 11, interface unit 12, etc. to control them. In this arrangement the operators have only to work as indicated on CRT. |
