content: It would help if you mention what project you're trying to do. Generally speaking I don't like using PC based test equipment, it has never really lived up to the promise IMO. You can get older analog scopes for next to nothing and for many things they are just fine.

content: Quote from: WindowsG Gaming on March 31, 2017, 08:47:32 pmYou could do this already with your sound card.But if you want to do more with electronics, like maybe programming an Arduino, a digital scope would be best, because you can debug things like SPI etc. much easier with it than with an analog scope. The cheap PC USB scope would work for this.

content: I've seen people give away older oscilloscopes for free, but it helps a lot to find one locally because shipping a big heavy instrument is not going to be cheap. $80 is cheap for a good scope though, many of those "crappy old" scopes cost as much as a brand new car when they were new and they still perform well. Oscilloscopes are not like computers and smartphones that get outdated rapidly, there are lots of 30+ year old scopes that perform as well or better than brand new gear that costs thousands. You can't buy a brand new scope for much less than $400 for a real oscilloscope that isn't just a toy. Expect to spend another $50 for a pair of reasonable low cost probes. Decent test equipment is expensive but it's an investment that will last decades properly cared for.

content: You might still get one for peanuts. Like I said, I've seen numerous people give away old 20MHz analog scopes, if you post your location somebody might have something for you. You don't need anything fancy just starting out and learning to use it. You can always upgrade later if you decide you need something more advanced.

content: The oscilloscope is really the "King of Test Equipment" and any (working) oscilloscope is better than no scope at all. Even though I 'm not really a fan of usb-computer-based scopes, the 60 dollar Hantek might not be such a bad deal for you. Especially since it does come with probes. Consider it to be a learning tool. Then save up for that Rigol z-box while you happily use the Hantek and get experience. Mow 20 lawns?

content: QuoteIt is if you have to go on the road and your laptop doesn't play well with your PC scope.(I have a PC scope -- a Link DSO-2102M --- it works through a bidirectional parallel port interface and the software runs on Win98. Fortunately my ThinkPad 600e has the right stuff....)

content: Had a it of a look at the Hantek and poked around eBay ... and found this:http://www.ebay.com.au/itm/Hantek-6022BE-PC-Based-USB-Digital-Storag-Oscilloscope-48MSa-s-20MHz-2-Channels-/252839378758?hash=item3ade66bf46:g:gYIAAOSwzhVWqIMyFor the price, you have to wonder - What did I just buy?All the signs say "Beware" - new seller, not much feedback, private listings, crazy price, confusing range of products.... but for the money I thought it would be an interesting experiment. If I really get uptight about my $16 AUD, I have PayPal to turn to.I'm almost waiting for the excuses to start straight away - but there is always the possibility........So - what do you reckon? Will I get something and, if so, what will it be?

content: Quote from: danadak on April 01, 2017, 12:47:01 amPlease donotuse the Saleae software with this no-name knock-off analyzer. Salae's software is not "free, as in "free to use for whatever purpose"; it is only licensed for use with their own logic analyzer hardware. It's bad enough that people have pirated Saleae's original hardware design; we should not make it worse by using those knock-offs with Saleae's own software...Saleae has since abandoned this basic design and moved to upgraded products, which include analog channels. Hence it might be OK to buy one of those Chinese hardware clones, which certainly does a nice job if 8 digital inputs at 25 MHz sampling rate are sufficient for your needs. Please use Sigrok software with it (https://sigrok.org/), which is truly free/open source.

content: QuoteWhile I agree with you that Saleae software should only be used with a Saleae device, I'd like to comment on the "pirating" of their hardware design.When looking at the schematics for the Cypress FX2 eval board , AN4053 of their set of FX2 application notes  and their supplied firmware example , it becomes clear as day that the initial Saleae hardware was really not much more than a slimmed-down reference design with basic protection (polyfuse, current limiting resistor on each logic channel). The firmware was also almost completely written by Cypress already, only had to have their proprietary Saleae control protocol added to it. The real brain power went into their GUI, which is definitely nice.My point? There was no pirating of the hardware design because they didn't add anything non-trivial to the material that Cypress itself already provided. I'd say that's fair game to reproduce as any hardware engineer could've whipped up the circuit easily using the reference design. For their newer designs, this is not true anymore, however.Just wanted to leave that here in case someone stumbles across this thread and thinks Chinese FX2 boards are cloned Saleae hardware.http://www.cypress.com/documentation/development-kitsboards/cy3684-ez-usb-fx2lp-development-kithttp://www.cypress.com/file/139866/downloadhttp://www.cypress.com/documentation/code-examples/ez-usb-fx2lp-throughput-measurement

content: If you want a scope and can pay a little more than the Hantek, look at the GW-Instek GDS-6112 100 MHz scope. Link herehttp://www.ebay.com/itm/GW-INSTEK-Curser-Readout-Analog-Oscilloscope-GOS-6112-100MHz-Broken-Handle-/132159285511?hash=item1ec54ea907:g:mkcAAOSw44BYbShb.These are from the ITT bankruptcy. I just grabbed one and it works perfectly. Better yet, it's a standalone.
