What is the minimum admissible quality of an osciloscope

[bugler]

Hi,

I have found this osciloscope in ebay: Osciloscopio HAMEG HM-605 60Mhz + Sonda en venta en eBay.es (finaliza el 24-nov-10 22:24:34 H.Esp)

How good (or bad) is it? Would you say is good enough to start learning electronics?

Thanks.

To start learning then certainly. 60MHz is quick for most home stuff. The mkind of repetition rates I am expecting (as a newbie on this forum) looks in the milli-secs. Even my very old and dodgy 100Hz scope does more than is needed to look at the waves of a bedini cct.

If your dipping your toe, then 150E is pretty decent... no point spending much more unless you know your gonna need it.

Thanks for your answer.

WHat is 150E?

So the osciloscope on ebay is good enough? thanks.

150 euro ... I think it was priced at 141 euro or something ... very quick look anyway.

Like I am doing in this with a basic SSG .. start small !!

I think you may find that the SSG delivers high voltage, very
sharp spikes, and this requires a very good oscilloscope to see
them properly.

Schools sometimes have good gear. Do you feel that you could ask
your old Physics teacher if you could bring it in and test it on their
best scope?

Hantek produce a range of interesting USB boxes which put the
scope output on your computer screen. Very useful Mhz.

Could you post info about these Hantek? Which one would you advise? How much would it cost?

Thanks.

Could someone who's plotted the waveform of an SSG on a fast scope give us the desired Rise Time of the pulse in uS ? That should pretty much determine the minimum Frequency Response needed.

This is the sort of thing:

You need to be sure that your computer and operating system
are sufficient.

They can be found on Ebay.

I feel lost.

Which one is good (and cheap) enough? Please take into account that I am a complete newbe.

Is it the HAMEG HM-605 60Mhz a good one or not?

I have a Hantek 60MHz dual channel DSO USB scope.....and it works lovely

around £130 as i recall

The osciloscope in ebay is also 60mhz and it is 10 years old so much better a small and new one for £130 (153€).

If its in good working order then it should make a good starting out point for a newbie. You need to learn about their differences. With analogue scopes its recommended to have 3 to 5 times the frequency's your working with. If your just working with 5mz and below a 25 Mhz would be all you need. 10mhz frequency's would be a 30 to 50 mhz analogue scope. 5 times is better.

Hi Bugler, and all. I have a Hantek dso 2250 and it works great for this stuff. I bought an old tektronix 465 off of ebay and it was not working properly, dont know if it was sold bad or broken in shipping. The are very heavy so shipping can be detrimental to them. The nice thing about the Hantek or any usb scope is when you are learning about electronics and learning how to use the scope properly, you may can use the computer display to check if you are reading the scope accurately. Just makes it easy to check your work. you can save screen shots and post them here too.And if you want to debug something in the car or garage, just your laptop under arm and the scope in your pocket. member Gotoluc uses one and he has done some great work with resonant coil tutorials with that scope ,check him out. Good luck with whatever you get.

Hi all,

thanks for your answers.

I decided that when the time comes I will buy the hamtek. I saw that they have 200mhz osciloscopes for less than 200€.

Cheers.
