content: Ill probably have to buy a new function generator..because my Rigol 1022u now have a corrupted firmware..(firmware upgrade fail)I generally works on filters and troubleshooting, I don't need of the most expensive piece of equipment, so my choiche is between this modelsRigol 1022z (Ill buy this for the higher freq. of the arbs, better signal purity and personally a better U.I)Siglent SDG1062X (Ill buy this for obv the 60Mhz, 500€ on Batronix)Personally I haven't needed more of 25Mhz, and also I have a Rigol scope, my budget is of 500€ but batronix sell the 1022z for just 400€ inc. 19% VAT and free ship (I live in Italy, and Batronix is in Geramany) and that 100€ euro will usefull to upgrade my soldering iron (a stupid WHS40) to a Ersa I con nano with some tipsWhat should I to do?Ps (If Rigol can't do nothing how much can I do from that Rigol 1022u?)

content: I couldn't make up my mind between these two AWG, but after I saw a DG1032z for the price of 1022z at rigol clearance sale, I pulled the triger on DG1032Z, Siglent and Rigol are very similar, each has it's highlights, put both spec side by side and decide witch give more of what you need. For me, larger arbitrary wave form memory was more important then two time smaller Vpp output. But your mileage may vary.

content: Quote from: sainter on December 13, 2017, 01:33:26 pmThe thing is that I don't know the fidelity of the siglent, I have read about the 15Mhz square wave of the Rigol 1000x is just crap, Ill buy the one that have more fidelity, I use Arb not that much, so I don't need of a lot of memory, but I need of a pretty good signal (I don't expect a pure square wave at 500000Mhz, because the budget of 500€ is pretty low, but I need of something thats good in this price range)

content: Hi NiaDebesis,I have RIGOL DG4062 for sale.I have purchased it few years ago but I barely use it.So it looks like brand new. I have all the things RIGOL ship it withand I believe I will find the original package as well.Now I have purchased Siglent SDG6021 so the RIGOL one I don't need anymore.I am willing to sale for a good price.In case you are interested please let me know and I will make you an offer.Dimitar

content: Siglent does have a long enough history with function generators so they got most issues ironed out. OTOH if you just need a simple generator you can also look at the ones from Feeltech.

content: Quote from: tautech on December 13, 2017, 06:54:41 pmThat is physically impossibleSerious though: IMHO it is lame some function generators limit other waveforms except sine wave to 1/10th of the sine wave bandwidth. Please let the user decide what is acceptable or not!Quote from: NiaDebesis on December 13, 2017, 07:00:16 pmI don't know exactly what you mean by 'signal fidelity'. Do you mean low jitter? Low distortion? High amplitude?I have a very old SDG1010 (probably one of the very first which came out of the factory) and so far it has been doing what it should do (except for log sweep).

content: Quote from: nctnico on December 13, 2017, 07:06:14 pmLow distortion, low jitter, fault of my englishI thought that buying a Function Gen. Of the same company of my scope will maked senseSo between the 1062x and the 1022z the first will be a better choiche? I care only about of the quality of the signal, not that much of the bandwith (my scope is only a 100Mhz cant take for example most of Harmonics in a Square wave at high frequency)And that siglent appear to be a very nice unitHow is the support in Europe?(I have emailed Rigol about the prpblem at my DG1022U 3/4 days ago..and nothing for now)

content: Support in EU is decent. Rigol has its own repair lab close to Munich and the distributors are typically available for supporting the users with or without warranty.

content: I’ve got a DG1022Z. While not perfect, it’s good value for money. The modulation and marker generation capabilities are pretty good. Semi review here:https://www.eevblog.com/forum/testgear/dg1022z-any-user-experience-with-this/

content: Quote from: NiaDebesis on December 15, 2017, 06:45:13 amThen you might like to look at the SDG1032X as it's ~140 EUR cheaper and apply similar tricks to improve it like what's done with 2042X.Then start a thread about doing it like the 2042X has.

content: Quote from: tautech on December 15, 2017, 07:08:50 amSo the sine of the 1032X is upgradable to 120Mhz??Compared to the rigol 1000z seems to be a little bit worse in the reproduction of the waveforms

content: Quote from: NiaDebesis on December 15, 2017, 11:06:26 amRumor has it to 60 MHz, the same as 1062X.1000X models do sine and square to the same frequency.2000X models only do square to 25 MHz.It's all in the datasheets.

content: Quote from: tautech on December 15, 2017, 11:33:14 amHm..that will be pretty good! But it remain a 150Msa/s low arb memory (very low). The Easy Pulse techonology make a real difference?
