If you are wondering which is better between lab scope vs oscilloscope, then maybe you just have come to the right place!
In this guide, you will better understand their key differences so you can choose the tool that best suits your needs.
Both devices are laboratory instruments. While a lab scope generally measures voltage and time, which is crucial when there is a rapid change in signal, an oscilloscope assesses the waveform of electronic signals.
As of now, you may still find it difficult to understand so just read on!
Lab Scope Vs Oscilloscope – Comparison 2020
Lab Scope Overview
Lab scope is common equipment that you can find on test benches. In fact, this is widely used upon the invention of the cathode-ray tube (CRT) technology.
Anyway, it is very useful in solving complicated and tough electronic problems, that is why it is widely used in automotive diagnosis.
Here are some of the features of a lab scope:
Rapid Measurement of Voltages
Sometimes, a lab scope is compared to a two-dimensional voltmeter. However, the latter can provide accurate measurements when the level of voltage is steady. With a lab scope, you are capable of analyzing and measuring voltages that are rapidly changing.
So even if the signal changes a lot, you can still measure time and voltage on the display. Specifically, it can show you the current-voltage levels, changes in voltage, and frequency of the change.
Unlike traditional voltmeter, this device can provide not only two channels or input connections. In fact, some products in the market offer more. And in this case, it can manifest more traces of voltage at once.
Switches and knobs may look confusing, especially if you have a general-purpose scope. But with this device, you can get simplified control so it won’t be hard for you to use it. Anyway, in a typical setting, you are only required to use about 3 or 4 knobs.
