I know what it is I have never seen one or used one. I do tv repair and am still learning. I mainly swap out boards but I seen some of these oscilloscope kits on ebay to make one for like 20.00 and I would like to do little projects like that as well as make the esr meter. but im wondering could I use this oscilloscope for anything? what type of stuff could I use it for?

Re: never used oscilloscope what is it for?
$20 Scope?
As far as 'What scope is for?' I think we went through that before:

Re: never used oscilloscope what is it for?
I do component level repair and quite complex never and rarely use a scope mainly my meter. I plan to get one soon for checking wave forms it can be very useful.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.

Re: never used oscilloscope what is it for?
Yes, they are basically worthless.
Much better to pay $50-$70 for an old analog scope, dual channel, at least 20MHz bandwidth and you're good.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello.
I have jut got my first analogue oscilloscope. An Isotech 620 20MHz.
I want to learn how not to damage it, and I found instructions on the internet obscure.
They talk about ground, earth, floating ground, this, that....
But they don't actually say anything anything useful so far.
I want to know:
Don't connect exactly this to exactly there or it blows up.
For example, I am tracing a signal from a function generator in an audio amp, or testing for voltages in different parts of a circuit.
I want to know what not to connect... -
I have recently acquired a Dynamco D7100 analogue oscilloscope without a user manual. As this is the first time I have owned or used an oscilloscope I would like to try and find an instruction book. The manufacturers no longer hold any information and a Google search only found one site but when I downloaded a 'service manual' all I got was gobbledegook. Any help would be gratefully appreciated or even pointers to a generic manual where I could learn more. -
All,
Some of you have helped me in the past and I am very appreciative of all the help! (I have fixed TVs/Stereos/ and other small appliances with your efforts...Thanks so much!!!
Today I went to a local HAM Radio Festival. It was one of the smaller ones in our area. My stepfather is the HAM operator. I tinker in electronics but am a Software Programmer (27 years now).
I was looking for a few odds and ends for some electronics work I have to do for the household/farm. Typically these type of shows have the grab bags or a electronics vendor... -
Hi, i have a Lenovo S145 that after 20 seconds shutdown and restart (it's working correctly on thse 20 seconds)
everything seems ok, but on Vcore inductor ( this is an i3 with just 1 switching power supply for CPU)
there is an output to teh CPU with a spike.. seems that inductor can't handle the input...
replaced the capacitor (330) and the inductor (R15) without any change
any idea? very thank you!
input of the inductor seems as usual... only strange thing is that the upper/lower voltages seems to be 21V (main power line is 19.3) ... but not sure this... -
Searched online but wasn't able to find. Trying to locate a copy of this document - AutoLeap Oscilloscope Handout.
