摘要：PURPOSE:To realize compatibility between reasonable resolution bad on the characteristic of a test material and test speed, by connecting plural D/A converters subordinately which performs the D/A conversion of a binary code and issues the integral output of a ramp wave signal. CONSTITUTION:Two D/A converters are provided in a device, and the D/A converter 1 is designated as a main converter, and the D/A converter 2 is t as a subordinate converter. And by connecting switches 8, 9, and 10 to contact (b) sides, an operation of high resolution mode is performed, and a clock pul signal is inputted to a binary counter 6. Next, a carry signal is inputted to a binary counter 5, and an analog signal l0 is outputted with the resolution of (the number of bits of the converter 1 + the number of bits of the converter 2) by functions of both converters 1 and 2. And by connecting the switches 8, 9, and 10 to the contact (a) sides, an operation of high speed mode is performed, and the clock pul signal is inputted to the counter 5, not to the counter 6, and only the converter 1 is operated, then, fast outgoing can be realized. In such a way, it is possible to perform the outgoing in which the compatibility between the resonable resolution bad on the characteristic of the test material and the test speed is realized.
