摘要： A memory control for use with a digital oscilloscope having a display and a digital memory storing a sequence of signal samples. The sequence of signal samples is cyclically read from memory and displayed. The memory control adjusts the memory access operation to provide a controlled signal flow to the display at a rate within the slew-rate limits of the graphic display. In the memory control, the point slew, or distance over which the display beam moves from the present data point to the next point, is measured. If the point slew relative to the time interval between displayed signal samples exceeds the slew-rate capability of the display, the signal flow from the memory for subsequent data points is reduced or inhibited for a time sufficient to allow the display to reach a coordinate position corresponding to the desired data point.

摘要： An oscilloscope to sequentially store, process and display an electrical input signal according to various signal events and characteristics. The oscilloscope is physically and functionally modular having both selectable hardware configurations from among various "plug-in" modules and selectable processing and display features chosen from among a predetermined selection by software control contained, in part, within the plug-in modules. The particular control settings, as well as a representation of the signal itself, is recorded on a removable storage device, such as a magnetic disc. High frequency signals are sampled, digitized and stored in a high speed intercascaded signal memory, independent from the program and data memory associated with the oscilloscope signal processing.

摘要： A circuit for precisely measuring very high-speed recurring waveforms includes a comparator coupled between an analog input terminal and a successive approximation register. A digital-to-analog converter is also coupled between the digital output circuit of the successive approximation register and the second input terminal of the comparator, and a high-speed digital latch is coupled between the output of the comparator and the input of the successive approximation register for freezing the output states of the comparator upon the application of hold signals from a hold signal generator means, so that a first sequential series of hold signals are applied to the latch, coincident in time with the occurrence of a first portion of the recurring analog waveforms being measured, until the successive approximation register completes its measurement of the voltage amplitude of such first portion. A counter in the hold signal generator means is thereafter stepped, to enable the measurement of a second portion of the recurring waveform, adjacent the first portion, to be carried out by the application of a second series of hold signals, each coincident in time with the occurrence of the second portion of the waveform, until the voltage amplitude at the second portion is evaluated by the iterative operation of the successive approximation register. The counter is again stepped, and the process is repeated until numerous points upon the recurring waveform under examination are measured.

摘要： An oscilloscope having multiple controls, wherein control functions are selected from a plurality of functions. Controls are located adjacent to the oscilloscope display which indicate the control parameter label and control parameter values. The control parameter selection is implemented by software program control.
