摘要： A system and method for calibrating oscillograph channels assigns the same value to a drawing parameter of each channel. Each channel receives a signal sent by a signal generator. The oscillograph calculates a voltage difference between a standard signal voltage of a standard channel defined by a user and a signal voltage of each of the other channels. A sequence relationship between each of the other channels and the standard channel is determined. The oscillograph adjusts a deskew value of each of the other channels until each voltage difference is in an allowable range according to the sequence relationship.

摘要： In a multi-channel oscilloscope a method of calibrating interleaved digitizer channels initially calibrates each digitizer channel to produce a bandwidth enhanced filter for each digitizer channel to match the respective channel frequency and phase characteristics. The oscilloscope is then configured for interleaved operation whereby an input signal is applied to at least two digitizers via a switch through a common preamplifier to produce a reference digitizer channel and an interleaved digitizer channel where the bandwidth enhanced filter for the interleaved digitizer channel is now not correct. Fast Fourier transforms are performed on the data from the reference digitizer channel and the interleaved digitizer channel, from which are derived a match filter for the interleaved digitizer channel so the interleaved digitizer channel and reference digitizer channel are matched in phase and magnitude at all frequencies.

摘要： A method and apparatus of calibrating electronic scales for the horizontal axis of an oscilloscope is provided. For each of two electronic scales or cursors, output voltages of a horizontal deflection circuit are generated. A measurement is made to determine a time interval in which the voltage of a sweep waveform, generated by a sweep waveform generator and appearing at the output of the horizontal deflection circuit, passes the two output voltages. The slope of the sweep waveform generated by the sweep waveform generator is adjusted such that the time interval coincides with a target time interval.

摘要： An automatic skew calibration technique for a multi-channel signal source uses a cross-coupled flip-flop calibration circuit and a microprocessor to align the timing of a pair of signals from the multi-channel signal source. The flip-flop calibration circuit indicates which of the pair of signals is leading, and the microprocessor uses the output of the flip-flop calibration circuit to determine in which signal source to adjust the signal delay. The signal source is incrementally delayed by the microprocessor while the microprocessor also observes the output of the flip-flop calibration circuit. When the flip-flop calibration circuit indicates a time interval over which the relative time position of the input signals changes, then the microprocessor determines a calibrated value for the signal delay, completing skew calibration of the multi-channel signal source.

摘要： The method of tuning a flyback transformer in a cathode ray tube control system, for minimum ringing, which comprises the steps of adjusting the lateral position of the center plane of the high voltage or secondary coil, with respect to the center plane of the low voltage or primary coil, placing an electric sensor in the vicinity of the high voltage coil to pick up a signal, which is a function of the current in the high voltage coil, and applying that signal to an oscilloscope, and noting the change in amplitude of the ringing component of the signal as a function of the lateral displacement between the two coils. By this means, the selected relative position of the two coils which provides a minimum amplitude of ringing is found and the coils are locked in that relative position to each other and to the magnetic core.

In a repetitive-sweep display, the leading edges of incrementally delayed successive pulses are slewed across the display screen.

摘要： An oscilloscope probe calibrating system for a single terminal probe and a differential probe includes an oscilloscope, a main branch module, a sub-branch module, and a resistor. The oscilloscope includes multiple inputs for receiving signals from the single terminal probe and the differential probe, an output for outputting an original calibration signal, and a display module displaying the waveforms of the original calibration signal and the signals from the single terminal probe and the differential probe. The main branch module converts the original calibration signals to a number of first calibration signals. The sub-branch module converts the first calibration signals to a number of second calibration signals. The sub-branch module includes a single terminal sub-branch module and a differential sub-branch module coupled to the main branch module. One end of the resistor is connected between the main branch module and the differential sub-branch module, and the other end is grounded.

摘要： A method and apparatus for correcting for deterministic jitter in a sequential sampling timebase. The value of a fine analog delay is held at a substantially constant nominal rate during a duration of a counting of a digital clock. A time difference between a trigger at which a fine analog delay starts measuring time and the occurrence of a digital pulse of a stable clock used to count a coarse delay is measured. An input waveform is sampled at a sample time having a nominal delay time. After sampling, a desired compensation time is provided for the sample of the input waveform in accordance with combinations of three independent variables defining a calibration table. The waveform is reconstructed by shifting a delay time of a sampled value of the input waveform from its nominal delay time in accordance with a value defined by the calibration table.
