Keysight DSOX1102G Oscilloscope

I will talk about my feelings about Keysight oscilloscopes. Keysight oscilloscopes are excellent in quality and performance. They are one of the best and most advanced oscilloscope and measuring instrument manufacturers. The 1000 X series is a popular series with a high cost performance. For ordinary test applications, one of the 1000 X series is enough.         

The DSOX1102G oscilloscope belongs to the InfiniiVision 1000 X-Series oscilloscope of Keysight. The bandwidth of this model is 70/100 MHz. The 100 MHz should be an upgraded version. The 1000 X-Series oscilloscope has two standard probes: 75 MHz, switchable 1:1 or 10:1 passive probe (N2142A) and 200 MHz, switchable 1:1 or 10:1 passive probe (N2140A). In addition, there are several other probes, such as the AC probes of N7040A, N7041A and N7042A. When choosing an oscilloscope, people only pay attention to the performance of the oscilloscope, but ignore the use of the correct probe to improve your measurement reliability. The performance of the oscilloscope is important, but it is also important to use the correct probe and the correct test method. Therefore, the probe must have the least impact on the detected circuit and hope to maintain sufficient signal fidelity for the measured value. If the probe changes the signal or the circuit in any way, the oscilloscope will see a distortion of the actual signal, which may lead to incorrect or misleading measurements. Therefore, there are many things to note when purchasing and using probes correctly. Only probes that match the oscilloscope and the circuit under test are the probes you should choose and use. For example, for high-voltage testing, you should use a dedicated high-voltage probe. After distinguishing the positive and negative poles, you can power on and start measuring only after confirming that the connection is correct. When both test points are not at ground potential, you need to perform "floating" measurements, also known as differential measurements, and use professional differential probes, etc.
