    摘要： A method for rasterization of a set of voltage-versus-time data-address pairs into horizontal and vertical locations of a multi-bit raster display memory of a digital oscilloscope or similar electronic data acquisition instrument is disclosed. It provides a new way of controlling digital intensity, by allowing the operator and/or a function based on the instrument's trigger rate to set the number of intensity units available for brightening the pixels affected by the rasterization of each acquisition data pair. If a vector has more pixels than there are units of intensity available, the number of pixels that are to be brightened is limited but spread out over the vector's length by an algorithm that includes at least some degree of randomization. If there are more units of intensity available than there are pixels to put them in, the extra ones can either be distributed into each pixel or randomly added along the vector or ignored. If the vector has no length, all of the available intensity, or some lesser amount of intensity, is put on one pixel. Setting a small minimum vector length, below which only limited vector fill is used, can save time by limiting the amount spent on insignificant details. Setting maximum and minimum intensity levels for those pixels that are affected by the rasterization process can limit saturation and assure that areas that receive only one or a few attacks will still have an intensity level that is perceptible. Sparse vector rasterization avoids the hard binary choice between using a dot mode or a vector mode, and gives the user an analog-like intensity control that produces a perceived continuum of viewing choices. It does this while maximizing the number of pixels updated within the context of how many waveforms are being acquired and need to be processed.

    摘要： A system for displaying waveforms representing an input signal includes a display subsystem, coupled to a source of the input signal, for displaying a waveform representing the input signal in response to a display control signal. A trigger circuit is coupled to the input signal source and detects a trigger event. A time displacement circuit is coupled to the trigger circuit and generates a time displaced trigger signal a controllable amount of time after detection of the trigger event. A switch is coupled between the trigger circuit, the time displacement circuit, and the display subsystem. The switch selectively generates a display control signal in response to either the detected trigger event or a time displaced trigger signal.

    摘要： A signal acquisition system has a signal acquisition probe having probe tip circuitry coupled to a resistive center conductor signal cable. The resistive center conductor signal cable is coupled to a compensation system in a signal processing instrument via an input node and input circuitry in the signal processing instrument. The signal acquisition probe and the signal processing instrument have mismatched time constants at the input node with the compensation system having an input amplifier with feedback loop circuitry and a compensation digital filter providing pole-zero pairs for maintaining flatness over the signal acquisition system frequency bandwidth.

    摘要： A method of drawing a waveform image in a no dead time acquisition system, where consecutive drawing frames overlap, uses a master/slave relationship between two fast rasterizers. The master rasterizer draws a first display frame in response to a first trigger event in a trigger signal derived from an input signal. The slave rasterizer draws a second display frame in response to a subsequent trigger event in the trigger signal. The portion of the second display frame that duplicates data contained in the first display frame is either (a) suppressed when the first and second display frames are combined to form the waveform image or (b) displayed in a different shade/color. Alternatively the first display frame may be compressed by 50% to form a first portion of the waveform image and the non-duplicative portion of the second display frame is compressed by 50% to form a second portion of the waveform image, the first and second portions being drawn contiguously when the first and second display frames are combined to form the waveform image.

    摘要： A potentiometer which provides the function of an on/off switch includes a center conductor connected to a conductive ring and a resistive element concentrically disposed about the conductive ring. The resistive element includes a pair of termination pads and one of the pads includes a branch which is situated outside the outer periphery of the resistive element. As a wiper arm traverses the resistive element it remains in contact with the branch for a brief distance and then loses contact with it. This causes the value of the resistance in the potentiometer to make an abrupt shift in magnitude which can be used to initiate various switching functions.
