content: Hi guys, I could not find any information about Owon's AG1000 / AG2000 arbitrary waveform generators so I started a new topic.Does anyone have an experience with these :http://www.owon.com.hk/products_info.asp?ProID=177?However, buying thiscrapAWG directly from China (ebay) is still cheaper than buying some decent used function generator within the EU.I will probably end up with Rigol anyway but this piece of gear seems to be nice alternative, especially for its price.Owon AG1012 - 299 USDOwon AG1022 - 339 USDRigol DG1022U - 379 USDall prices are with shipping included.Rigol is time proven but Owon looks nice as well.

content: You say it's crap. Ok, why would you buy it? Also, you don't give a price. There isn't much to go on really other than you think it is crap but want to buy it anyway no matter the price?

I am desperate because I have been looking for a generator for a while and surprisingly hantek/rigol/sigilent/owon AWGs are way cheaper and easier to get than used Tek, HP, TaborElectronics function generators. At least in Europe.I will update my first post.

content: 4k and 8k point limits don't really allow these machines to be especially arbitrary. That said, the cost of making something like this has plummeted in recent years. You can make a good waveform generator for a small fraction of the cost of a few years ago.

content: Quote from: coppice on October 30, 2014, 11:35:16 amYes, memory limits are often mentioned. On the other hand I mainly use an AWG for something different than expected - voltage variation tests, dips etc. So I need only "few" points and fair DC accuracy. The output of AWG is then connected to some discrete power amplifier (A=3-10) and then to DUT.Square/pulse output * with a duty cycle control is mandatory for playing with DCDC converters. A sinewave output is for everything else like filters etc.* Do you know why for example Rigol has a duty cycle control only within 20-80% for square output and then precise duty control for a pulse output ? Is pulse generated differently ?

content: I had a chance to see Owon's AG1022F at Electronica fair. Above that I could compare the first impression against Siglent SDG1025.Both units made similar impression to me. Owon looks a bit cheaper but GUI is better. Viewing angles allow to have the AWG on a shelf which is nearly impossible in case of SDG1000 because of a poor LCD.The unit was there also as a "Peaktech".Conclusion: "not bad for the price, I may give it a try"
