content: Hello All,I did not know that there was a limit on the login time. I was posting comments about my Purchase today and went over the 60min time limit and there is no autosave to recover my draft.So here is the edited version.TEquipment: no Rigol 2072 in stock until mid August. Same with other locations I check. So I purchased the 2102 at a discount $1072.00 plus free shipping in the US. Should be here this time next week.Was going to get the Owon but after research (NO). Was then going to get the GW-Instek 2102A but after research (NO). That lead me to the Rigol. Thanks again.Next up: Signal Generator. The Tech advised against the Little Signal Trainer and said instead to purchase a Signal Generator. He said that I would get more usage out of the SG in the long run. I have a large work area but looking at the units on line, its sort of like the O'scope's. Some lay out and some have a smaller foot print like the DSO. I know the SG will be put away after a while of getting back use to working with the DSO. Anyway, whats the best unit for the money. I do not want to spend over $500.00.Sorry for being so blunt, I'm just upset about the Posting Timeout.Thanks again for the Rigol and any help with the SG.Howard

content: You can select the lifetime of your login session at login. You can even set it to forever. It's not a posting timeout, it's a login timeout. Not that that makes your experience any less frustrating, but it may help you avoid this in the future. If you spend a lot of time crafting a post, then it's a good idea to copy the contents to clipboard before submitting. If the server returns an error and eats your post, then you can just paste the contents and resubmit.

content: Rigol makes the 4000 series Sig gen, but I personally think those are a bit too expensive. I would recommend the Siglent 1000/5000 series, but it has less of the presets that the Rigol does.

content: Hello All,Opps! forgot to ask. I just purchased and have not received my FIRST O'scope, Rigol 2102. Was there some questions about the "SERIAL # and Date of Circuit Board" that I should of ask(TEquipment.net) before the Scope was purchased? Also I read about some "Modification" that yall are doing and what about Scope probes(should I get/order a better pair)?1) What's the latest "Serial #" that will have all the fixes when purchased off the shelf?2) What "Mods" are yall doing and do I "HAVE" to have them for the scope to be (%110)?3) Do I need to purchase other scope probes?Thanks for any helpHowardPS: still have not decided on what "Signal Gen."

content: Without knowing your requirements for a SG here is a link to a Siglent 25MHz 2-Channel Function Generator for $368 shipped free in the US:http://www.saelig.com/FGDG/FGDG013.htmI have no first hand knowledge of it just looking at it's specs. and price and my recent experience with a Siglent DSO. I like the combination of wave forms it producest.I just bought a SDS 1072CML from them - great price and fast free shipping (3 days after order) - just got it a day ago and still doing a combination of awe and a little disappointment with it as it is my first DSO after using only an old Tek 454. I'm impressed with it's features and quality - little disappointed with the slowness of response at times and what appears to be sample or quantization noise on the waveform. I know it is only 8 bits. I must admit, I would have gotten the Rigol 2072 if it were not for the extra $440+. Never having touched or used a DSO take this with a grain of salt.I'm still at mostly 'awe' point for what you get in the 1072CML for $322. Totally pleased with the purchase experience with Saelig. They included a free carry bag too - reminds me a beer cooler bag with it's heavy cushioning - but nicely done - 3 yr warranty too.GL!David

content: Quote from: dde33 on August 11, 2013, 04:46:41 amSiglent do not automatic "picture cosmetics" behind user back as perhaps some "nonamed" may use..Also Siglent sinx/x is very accurate and well balaced with front end BW. (it is not like "image cosmetic filter")Now, if want more nice image, there is separate adjustable DSP filters for both channels.Use of these for cleaning noise but not reduce signal details need some exercise and do not be fooled by these frequency rates in filters. Just adjust these from top to bottom watching your signal and keep care that it do not cut your signal but reduce noise. After some experience these can use well. But also now, if filter is on, be careful if you change timebase. It change filter automatically but least for this purpose, it is not at all optimized and it may cut your signal.With some signals it can also exerciese if without sinx/x get better result.If have lot of time and want do it just as playing or interest how it really works... there can test how these filters work (and how sinx/x work). It can do without real signal. You can make some "theoretical" signal to USB stick and read them to scope (they are now there just as captured single shots).These DSP filters can use so that you still get full risetime (or enough risetime for your signal) but it reduce quantization noise and specially noise what come some amount unmatched (gain/level mismatches and clock's phases inaccuracies) interleaved ADC'sI hope, Siglent later change something in FW and in selfcal procedure it may do this ADC's matching better. (this is well explained by tinhead somewhere in Hantek thread, what use same kind of principle in front end including ADC's)Of course Siglent can add post DSP for display cosmetics and what user can not on/off or adjust.(example in Hantek there is, and I suspect also some others have) I hope Siglent do not this and they keep this user adjustable filter what can adjust and what can on/off by user.

content: Hello All,Up and running with the new Scope. But I'm confused about the "Trial" firmware. Is it the same as the Rigol DS2072 as far as being unlimited?Thanks for any help/advise/insightHoward

content: I think everything is unlimited for the first 30 days or whatnot, and then you have to pay for the Rigol firmware upgrades. Just like the Agilent.

content: Hello All,Relearning to use an O'Scope again(DSO) is going slower then I wanted but its coming along. My SG Rigol 4062 shipped and will be here this Thursday. I'm confused though, I got my (DSO) on Aug 15,2013, it was 2 days later before I first turned it on but I noticed about two(2) days ago that my "TRIAL" information stopped showing up. That's not the 30 days that I was expecting. It's been less then 15 days and I always turned it off. Can anyone tell me if this is correct? I thought that all the 2000 series got the "TRIAL" offer?ALSO:1) I have a 4 Gig. Thumb drive but can not create a new "FOLDER". How should it be "FORMATED"?2) Does the DS2102 have a different "TRIAL" time?3) Does the Hacks apply to this Scope?Sys Info:SW:00.00.01HW:1.04) Do they need to be updated?Thanks for any help to a Newbie.Howard

content: Hello All,Sorry to make this separate, but I did do a search here and changed the Format of my USB stick to (FAT32 / 4096)..done. I move the stick back to the Scope and added a newdirectory1 to the Stick. I then erased it and entered through the Scope keyboard my own Sub directory name. But the DATE and TIME section showed......2023-5-1 23:04. The time seems to be the only thing correct. The same thing shows up on my computer also. Is this something that's already been corrected?ThanksHowardTHREADS MERGED

content: Quote from: hmlittle59 on September 02, 2013, 03:46:06 amThe trial time is a certain # of minutes (I think it was around 3100), it's not limited by days. As far as I know all the 2000 series has shipped with the same # of trial minutes. The keygen will work on all the 2000 series and now on the DSA815. Be advised that you should upgrade the firmware to the latest version (01.01.00.02) that can be found in the "Reviewing the Rigol..." thread started by Marmad to avoid possible S/N corruption.

content: I finally got that 4 button MENU option to work and it does appear that I do have the latest FW:00.01.00.00.03. and yes it did count down in "minutes" now that you mentioned it.....not days. I never thought to do the math on what was on the screen. They got me on that one.. Now that my minutes are up, can the hack still work? I did the download and "Wndow's" is looking for a program to run it. Do you know the name of that file?ThanksHoward

content: Hello All,My Rigol DG4062 just arrived today. Will not unpack for a couple of days, have to make room and figure out the setup. I set for a long time as this is my first of both to own. Thanks to ya'll for pointing me to RigolWhile moving my computer to be able to drill new cable routing hole's, my old backup power supply/surge protect was bumped and died(burnt up). Thought I lost my computer(again) but its OK. Just about all my data(99.9%) goes to a thumb drive or external HD. Lesson learned from the last time 3 years ago. It's a pain but well worth it. Went out and got a couple more for the house and real surge protectors. Any way.Thanks Again for all the help.Still need to fix/re-due my FW on my Rigol 2102 and go back to work at my paying job tomorrow.Howard
