For different channel input signals, sometimes we want one channel signal to meet one condition while another channel waveform meets a different condition, achieving a logical “AND” combination for the channels. For example, how can we trigger channel 1 on a high level while triggering channel 2 on a rising edge? The ZDS2022 oscilloscope not … Read more
Hello everyone, sometimes we encounter such waveforms in waveform measurement. Based on the characteristics of the waveform, we have set the appropriate edge trigger, but the waveform still cannot be displayed stably. What is the reason for this? How should we operate in this case? In the trigger settings, there is a function to set … Read more
An oscilloscope is a primary instrument for time-domain measurements. Currently, most digital oscilloscopes include approximately 25 built-in measurement parameters as standard supplements. By adding application customization options, the number of parameters can be increased to over a hundred. Even with such a vast measurement capability, some measurements must utilize existing measurement tools to derive results. … Read more
Before learning how to use an oscilloscope to reduce noise, let’s first understand how noise in oscilloscopes arises. Many people who have just transitioned from analog oscilloscopes to digital oscilloscopes may complain that the waveforms measured by their new oscilloscope are not as clear as those from their old analog oscilloscope, even doubting whether their … Read more
Improving the accuracy of an oscilloscope is not difficult, but attention to detail is required. This article will explore various methods to enhance oscilloscope measurements. Using Multiple Grids to Maintain Dynamic Range A common use of an oscilloscope (4 channels) is to sacrifice one-quarter of its dynamic range by attenuating the amplitudes of several signals … Read more
The oscilloscope measures the voltage applied to its input. In most cases, this is not an issue, but in certain situations, it is necessary to move the reference measurement plane and recalibrate the oscilloscope’s measurements. For example, if a minimum insertion loss impedance box (MLP) is used to terminate a measurement source with an impedance … Read more
An oscilloscope is a window to observe waveforms, allowing designers or maintenance personnel to see electronic waveforms in detail, achieving a real-time visual effect. Because the human eye is the most sensitive visual organ, it can perceive minute details and quickly reflect objects to the brain for comparison and judgment. According to the different classifications … Read more
In the field of electronic engineering, oscilloscopes are important tools for analyzing signal characteristics. When it is necessary to observe and stabilize the waveforms from two different signal sources simultaneously, how can electronic engineers achieve this? Below are the specific steps to efficiently stabilize the display of both signals on the oscilloscope. 1. Check Signal … Read more
Oscilloscopes Are Simple Yet Complex! But Why Are Oscilloscopes So Expensive? Most cost thousands or tens of thousands, why are they so expensive? Structure of Digital Oscilloscopes The Reason Oscilloscopes Are Considered Simple Is That An Oscilloscope Is A Test Instrument That Can Display The Dynamic Waveform Of Voltage Signals. An Oscilloscope Converts Time-Varying Voltage … Read more
What Is an ECU? ECU, or Electronic Control Unit, also known as the “onboard computer”, is essentially a microcontroller for automobiles. It is composed of a microprocessor, memory, input/output interfaces, analog-to-digital converters, and other large-scale integrated circuits, similar to a regular computer. In simple terms, the ECU is the “brain” of the car. It is … Read more
