摘要： An apparatus for displaying line and frame waveforms having different time-scales of a video signal on a display screen is described which comprises complex sweep signal generating means including a line sweep signal generating circuit 2, a frame sweep signal generating circuit 3 and a switching circuit 4, and horizontal axis drive circuit including a horizontal location arrangement circuit 5 and a horizontal axis drive circuit 6. The line and frame sweep signal generating circuits 2 and 3 generate line and frame sweep signals S.sub.2 and S.sub.3 synchronously with line and frame synchronization signals of the video signal, respectively, and the switching circuit 4 alternatively transfers the line and frame sweep signals S.sub.2 and S.sub.3, synchronously with the frame synchronization signal to generate a complex sweep signal S.sub.4.

摘要： The apparatus for displaying a clamp point on a screen includes an input amplifier; a clamp circuit which includes a sync separation circuit and a one shot; and a blanking circuit. The video signal is applied to the clamp circuit via the input amplifier and the output signal therefrom is applied to the blanking circuit to be modulated with respect to its brightness. Thus, the brightness-modulated clamp point is readily located on a screen of, for example, an oscilloscope.

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 apparatus for displaying a waveform of an input signal on a display includes a synchronization detecting circuit, a sweep generating circuit, a horizontal axis drive circuit, a switching circuit, a variable gain amplifier, a vertical axis drive circuit, and a vertical location arrangement circuit. The horizontal axis drive circuit drives the horizontal axis of the display on the basis of a sweep signal generated at the sweep generating circuit synchronously with a sweep trigger signal obtained by dividing synchronization detecting pulses from the synchronization detecting circuit by N (N-1, 2, . . . ). The switching circuit alternately transfers the input signal and a cursor signal at a high rate to provide a multiplexed input/cursor signal to the vertical axis drive circuit through the variable gain amplifier. The vertical location arrangement circuit generates a vertical location arrangement signal stepwisely variable synchronously with the sweep trigger signal to the vertical axis drive circuit, where the multiplexed input/cursor and vertical location arrangement signals are combined to provide a vertical axis drive signal. Accordingly at least two sliced portions of the waveform with the cursors are displayed on the left and right sides of the display in an enlarged/divided display mode (N.gtoreq.2), and the whole waveform with the cursors is displayed on the display in a normal display mode (N=1).
