Re: some tips on buying an oscilloscope please

You need to buy a book on them and read it 5 times before you buy! I would not have anything less than 100mhz. You need to be able to measure all aspects of the waveform for plasma. Also volts per division should be at least 100 v. A plasma waveform is around 300 v and my scope only goes up to 50v pere division. I can measure the waveform, but it`s hard sometimes.( probes) are a whole other book. You also need to be able to read timebase and volts my scope has cursers that give me a read out... nice for plasma.
It is nice to have a frequency counter too.
I am by no means an expert on scopes. I am still learning.
I paid 2000 bucks in 95 for mine so today it should be around 500 bucks with more features? and what about a digital scope?

I would pick up a cheap scope and learn on it then you will have a better idea of what you need and how much to spend. Good luck!

Hi guys,

Thanks for the info ,the ones i have been looking at are 100mhz 2 channel and has 2 50v per division controls. I guess the only way to really learn is to get one and experiment a little I guess if i get one and get a little stuck i could post some pics and ask for some advice on here..

Thanks once again

Re: some tips on buying an oscilloscope please

I was just looking at an l/g service manual ( plasma) and in diag it required 200mhz or more scope. I have a 100mhz and have been able to chase down waveforms, some are harder to trace and some are easy. I guess that would explain it. I am a little worried, I think more people should have spoke up here on this subject. I am afraid to look at scopes for plasma use :

1) These will not be around long (even though I love them)

2) I will end up buying yet another scope and spending too much money.

Re: some tips on buying an oscilloscope please

...?...

no problems with your ebay link at all.
but there was a spam post (advertising) by some random chinese bot between cadiman's and your post. tried to report it to the forum mods but that didnt really work. its deleted now.

btw..little tip for shortening ebay URLs..

always worked for me..
for different countries, just replace the top level domain with the one of the country you want (.com/.ca/.it/.de/.co.uk/...)

Re: some tips on buying an oscilloscope please

The Tek 465b is still a useful scope for most of the things I've needed to use it on. It was the scope of choice by many repairmen years ago, along with an HP that I don't recall the model # of right now. You might find one for less outside the UK but I know the VAT is a factor then. At least that one has a probe so it can be tested out right away. Did you bid on it? If not there's plenty of them around so just keep watching for the deal you need.

Yahoo! groups have a user group called TekScopes for discussing classic Tektronix scopes that you might find interesting, especially when it comes to calibration issues or faultfinding.
