50m and 100m are bandwidth indicators for both analog oscilloscopes and digital oscilloscopes.
The bandwidth of 50M and 100M in the oscilloscope refers to the frequency range that the oscilloscope is allowed to use. 50M can only measure or observe signals with frequencies below 50M, and 100M means that it can measure and observe signals with frequencies below 100M.
The upper limit of frequency is only 5KHz, which can be used by ordinary oscilloscopes. If you choose 100MHz, it can be used in a wider range, and the price difference is not very big. Nowadays, the difference between ordinary 50MHz and 100MHz is only 200 yuan or 300 yuan.
Someone asked if they want to buy a digital oscilloscope, whether it is better to buy a 50M or 100M one.
It is recommended to buy 100MHz, not only because the prices of the two are similar, but also because the higher frequency can expand the range of use in the future.
According to the current market repair of TVs, most of which are LCD TVs, the oscilloscope should be selected between 100M-300M (double trace or above)
