Cheap Oscilloscopes - worth it?

About :

Today's video was requested by many of you, so I took it properly so that you will be satiated :) First, for an overview, we will divide the oscilloscopes into 11 categories. Then we will look at 2 oscilloscope displays and 2 oscilloscope multimeters. We will talk about their pros and cons, and try them either on a basic hobby generator or in three practical cases. We will also show you how to make an inverter from a dead UPS. Mustool MDS8207: https://bit.ly/3vre3Ev Mustool MT8208: https://bit.ly/3BtDo4b Hantek DSO2D10: https://bit.ly/3ShCa2i Functional generator: https://bit.ly/3bolEg1 Power transformer from UPS: https://bit.ly/3bk2yYA Panel PWM controller: https://bit.ly/3Jp5xLR The author of the video does not take any responsibility for injuries and damages caused by electric current or discharge. Electrical equipment may only be designed by a person with 50 §10, to verify their security by a person with promulgation 50 §9, and to work on them under voltage independently only a person with 50 §7. Lay persons without electrical training should stick to low voltage sources (SELV, PELV) that are safe for lay activity. These sources must not have a potential difference higher than a small voltage even against the ground (yes, I am talking about devices galvanically connected to the ground). I remind you that interference by bridging a Class Y capacitor is not considered a loss of SELV galvanic separation, as these capacitors cannot be shorted to low impedance. Nevertheless, I recommend using two in series, and using a spark gap on the LV parts in addition to the MOV. I also recommend the MOV as protection at the output of the DC/AC converter, the snubber for mosfets also does not catch everything, that is, if it is present at all.
