    摘要: An inspection apparatus and method are disclosed for inspecting a magnetic disk or a magnetic head. A first reference signal generating source generates reference signals of a controllable oscillating frequency, and a signal switching means selects either a reference signal or test data reproduced by the magnetic head. Factors such as offsets and gain differentials among signal distribution paths, phase shifts of sampling clocks supplied to a plurality of AID converters, and frequency-dependence of the transfer function and phase response of signal paths are identified so that errors due to these factors can be detected. Based on the detected values of these factors and errors, reference signals are utilized to compensate test data errors.

    摘要: The present invention relates to a data processing device for mass spectrometry, in which measurements are performed in a high dynamic range without causing an overrange in an A/D converter in any TOF scan. A data acquisition circuit of a mass spectrometer includes an amplitude value computing circuit which measures and stores a maximum amplitude value of an ion detection signal, a gain control circuit for determining and setting a gain amount for the next measurement, and others. From the immediately preceding TOF scan data or TOF scan data plural times before, the maximum amplitude value of the ion detection signal is extracted. Then, before the next TOF scan, an optimum gain amount is determined based on the extracted maximum amplitude value to adjust the gain of the input signal, and the ion signal is sampled in the A/D converter.

    摘要: An output buffer includes inverters, a delay circuit for delaying an input signal, buffers and switches. The output buffer transmits a logic signal to a transmission path and, in accordance with an amount of signal attenuation in the transmission path, creates a waveform including four or more kinds of signal voltages. The buffers are redundantly connected in parallel, and the number of buffers concurrently turn ON is controlled by respective switches provided in series with output resistors of the buffers. By selecting the buffers of switches which are turned ON, the preemphasis amount and a number of preemphasis taps are adjusted through a selector logic selection signal so that the preemphasis amount is made variable and the ON resistance of the buffers is made constant.
