content: I am a beginner and am looking for a cheap/free old dual channel analog oscilloscope. I'm pretty broke, but really really badly want to get one and start doing things... Don't care if it's pretty, as long as it works. I can get leads if their are none. I would be forever grateful. If its free i'll happily pay shipping. Or if you'r close to or in massachusetts i can come get it. Thank you!

If you take the time to really dig in you will find a lot more. If you find something that you are not sure about, feel free to post about it and someone is sure to give guidance on it.

content: One other thing you can do is search ebay by location and see if anyone close to you has one. Then you can save the shipping and try to pick it up.

content: Quote from: Xion on August 12, 2015, 04:07:36 pmNot a bad scope at all, smidge high on shipping. Tek scopes are notorious for being reliable/dependable and as far as I know, 60mhz should be more than adequate to get you started. Another factor that comes into play is what your technical needs are and how patient you can be to search for one. I was very carefully monitoring my local classifieds several months and was able to snag a 100mhz Tektronix 465 for $50!

content: Quote from: Xion on August 13, 2015, 12:40:11 amDon't even consider it. Your first scope should definitely be a 2-channel scope. Single-channel scopes are special purpose items. You will frequently be looking at the effect that one signal has on another signal, so two channels are necessary for that.

content: Quote from: Xion on August 12, 2015, 04:07:36 pmThe Tek 2213a (not plain 2213) is an ideal first scope. The one in your link is a 2213 and has a broken knob (timebase selector is missing the "cal" and "10x zoom" red knob) and for those reasons is a "reject".A good used 2213a will probably cost you 100-150 dollars and will be well worth the money.ETA: The HP1741A linked up above would also probably be a good choice, although it's more complicated. If it's working 100 percent and you can get a good rate on the shipping, you might consider it.A usable pair of probes (Chinese of course) can be had for 20-25 dollars.

content: For a very inexpensive set of probes, there are some chinese knockoffs that another board member tested and found to be very good. They can usually be found for $8-15. I am actually going to be placing an order for a set this week.Found 'em for $7.90 at the time of this post:http://www.ebay.com/itm/291365415321Heres the thread with in depth analysis:https://www.eevblog.com/forum/reviews/cheapest-100mhz-oscilloscope-probes-hands-on-review/msg96821/#msg96821

content: http://www.ebay.com/itm/171891171613I have seen this guy posted repeatedly on ebay for the last 3 months. Each time dropping in price. 20mhz may not be the fastest in the world, but depending on your needs should suffice. Tenma is a good brand name and if you make the min $50 bid you will definately win. I have a passing familiarity with the seller too, they service TV/radio transmission equipment if I remember correctly. (They are like 25 miles from where I live)
