Okay so i am thinking about getting my first oscilloscope model GW INSTEK Curser Readout Analog Oscilloscope GOS-6112 100MHz for 95 bucks shipped. Without probes of course. What probes can i use with this. Yes i will need to learn how to use it however i have been watching endless hours of youtube vids how to run them. Also thinking Isolation AC power supply model ISO - 300 or build one like budm made. Will that work? Any advice or known horror stories on this model oscilloscope? Are u able to measure hot side with isolation correct? Thanks for any input.

Re: GW INSTEK Curser Readout Analog Oscilloscope GOS-6112 100MHz
Pretty much scope probes are interchangeable with each other. At 100MHz most things are just fine. I did a test on the el-cheapo P6100 x1/x10 made-in-china probes and they are indeed rated for 100MHz and if you can deal with some of the "construction shortcuts" they'll work fine for low cost. Yes you'll need isolation for virtually all oscilloscopes to view unisolated signals, and you're probably better off buying one unless you just so happen to already have the right parts to build one...
No clue about all the scope brands out there. Most of them just work, if they work. I have a virtually noname Vu-Data scope and it seems to work fine, along with Tektronix scopes which also work fine... -

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.
