Embodiment Construction

[0020] The present invention is specifically described below in conjunction with accompanying drawing:

[0021] combine figure 1 , a four-color display method for a digital phosphor oscilloscope, comprising:

[0022] Step 1: The collected data is sent to the collected data storage module after being converted by the analog-to-digital converter module, and the collected data is stored in the collected data storage module under the control of the receiving clock;

[0023] Step 2: The waveform superposition processing module reads out the collected data from the collected data storage module, and judges its superposition position in the waveform frequency value storage module according to the read data, and then reads out the waveform frequency value storage module For the frequency value of this position, add 1 to the frequency value and write it into the original position;

[0024] Step 3: The color conversion module is provided with four color modes of normal, reversed phase...

Abstract

The invention provides a method for displaying four colors of a digital phosphor oscilloscope. On the condition that a waveform is displayed in a normal color mode, an event generating frequency is represented by a default channel color and gray scale; an event with high generating frequency is represented by a bright color, and an event with low generating frequency is represented by a dark color. On the condition that the waveform is displayed in a reverse color mode, the event generating frequency is represented in the default channel color and the gray scale; the event with low generating frequency is represented by a bright color, and the event with high generating frequency is represented by a dark color. On the condition that the waveform is displayed in a color-temperature color mode, the event generating frequency is represented by the color grade; the event with high generating frequency is represented by a warm color, and the event with low generating frequency is represented by a cold color. On the condition that the waveform is displayed in a spectrum color mode, the event generating frequency is represented by the color grade; the event with high generating frequency is represented by the cold color, and the event with low generating frequency is represented by a warm color.

Description

technical field [0001] The invention relates to the field of oscilloscopes, in particular to a method for displaying four colors of a digital fluorescent oscilloscope. Background technique [0002] Digital phosphor oscilloscope is a general-purpose basic measuring instrument with a large quantity and a wide range, which is widely used in the research and development, production, testing and technical support of electronic equipment. Digital phosphor oscilloscopes are capable of recording voltage, time, and the probability of voltage change over time. Different color displays are required to quickly highlight events that occur more frequently during the measurement period or to highlight events that occur less frequently during the occasional anomaly of the measurement. model. [0003] Existing digital phosphor oscilloscopes generally have a color display mode. The frequency of events is represented by the default channel color and gray scale. Events that occur frequently ar...
