How do I use an oscilloscope to measure differential signals?A: The best way is to choose a differential probe, the measured signal is the most realistic and objective; if there is no differential probe, you can use two differential probe to the oscilloscope two channels (such as CH1, CH2), and then use mathematical operations to obtain th

USB high definition isolation oscilloscope, virtual oscilloscope, technical features and applications USB oscilloscope market leader, model HS5, HS6, cs448 four-channel high definition isolation oscilloscope. The instrument has four differential input channels and a variety of probes that can be used for measurement in

load being added to the measurement? -Answer: No. I started to get dizzy: first, the power supply noise measurement should be when the power supply in the maximum output state of the indicator, if there is no load, it will not know the actual state of the power supply after the load. More importantly, the Oscilloscope standard probe is 10:1, in other words, the noise signal comes in, has been attenuated to the original amplitude of 10%, even if the

During the test, how much bandwidth does the oscilloscope choose? First, check the following instance. It can be seen that the larger the bandwidth, the richer the signal frequency component that can be displayed, the closer the real signal waveform. 1. Precise bandwidth calculation of an oscilloscope Perform the following steps: A. Determine the fastest increase/decrease time of the tested

Before understanding the structure of the probe, You need to first understand the structure of the input interface of the oscilloscope, because this is the place connecting the probe, the input interface circuit of the oscilloscope and the probe constitute our detection system. Most of the input interfaces of the oscilloscope are in the BNC or BNC-compatible for

Recently made a mistake Test action:test Scenario: direct from the mains socket to access the 3W non-isolated switching power supply circuit board, using an oscilloscope to test the output voltage, when the oscilloscope through another outlet directly from the mains powertest Result: in the oscilloscope to the output negative moment, the leakage protection switch

supplies, and other typical oscilloscope applications. 1. Differential Measurement characteristicsThe probe can be divided into passive probes and active probes in general, while wide bandwidth oscilloscopes and active probe users also need to choose between single-ended probes and differential probes. The pair of lines that carry the differential signal is called a differential route. This article is mainly about the differential probe. The most obv

Some interfaces are also provided to allow plugin to add more graphic effects. Many players do not have this basic function, probably because most of them d

The previous simple introduction of the Android program in the development of the use of Audiorecord and Audiotrack, this time combined with Surfaceview to achieve an Android version of the phone analog signal oscilloscope. Recently the Internet of Things is very hot, as a mobile phone software developers, how to do not modify the phone hardware circuit under the premise of integration with third-party sensors it? The microphone is a good ADC interfac

Ubuntu runs on the oscilloscope and can still be used for mine clearance. following last year's appearance of the "Starling on the oscilloscope", I found another person! This is to install Ubuntu on the oscilloscope! It's so brave. What I accidentally saw in imageshack. us: download it and check out... From the meta information of the photo, it should be taken by
