So.

I have sds1202x-e and cannot start measure succesfull. Is it so hard really? I just have for example one Monitor Power Board and want to see the graphic of the output voltage(5v in this case). The BNC of the probe goes to Channel1 and where to put the aligator which is on the probe cable - on the Earth metal place on the osciloscope, on the board earth or?! There is some metal terminal on the osciloscope above the earth terminal. It`s for something like "Compensation" or similar...

I just want to know where to put Probe1 BNC and that aligator and should i do something else to begin doing elementary osciloscop measurements

Thanks in advance

Could you just tell me about receiving true graphic ?/connecting probe and grounding/

Here`s the picture of the scope :

Have you tried reading the manual for your scope?

 

yes. now i will look again and deeper to try analyze

There are also some really good videos on scope usage posted in this forum. Tried to find them but did not look real hard either. I think the thread is in Electronic Resources.

 

Found it

Connect the probe tip to the circuit
point to be tested and connect the ground alligator
clip of the probe to the circuit ground terminal.

Can i attach the aligator to PCB "Suns" ?
For example this board
https://ae01.alicdn.com/kf/HTB1WnI....-LCD-LED-Screen-Controller-font-b-Board-b.jpg
has 4 of them

 

Connect to ground. Exactly as it says in the instructions.

 

For measuring the probe goes to test poing and the grounding aligator goes to ground of the Board. I ask if i can put this aligator to one of those 4 suns.

The next and maybe final question for now is where to find that ―Compensation Signal Output Terminal‖ of the probe
because i dont see it in paper manual of the probe

Nice day

 

...........where to find that ―Compensation Signal Output Terminal‖

You connect the probe to the top terminal and the ground clip to the bottom terminal shown here on the right bottom of your scope.
Then you adjust the probe compensation to display a clean, flat-top square-wave on the oscilloscope with no undershoot or overshoot on the leading edge.

 

What's a "suns"?

 

Hello,

@BR-549 , there are 4 mounting holes with stars for grounding:


These can also be used for the ground connection of the scope probe.

Thanks Bertus.

 

i think now everything should be okey. Before minutes did this compensation

And for protocol i am defenetly not SHE

 

Top left corner of that scope is a blue button marked "AUTO SETUP". It can be your friend when approaching an unknown waveform. Hit it first, then see if Yu want to change the time, base offset, voltage scaling, or whatever.

It should get you somewhat close and uickly to what you want to see.

 

Considering the OP seems to ignore some basics, could he be warned that he needs to make sure the circuit has a PSU providing isolation from mains. I find that a serious concern.
