content: I was just setting up my Siglent SDG5082 (Firmware 5.01.01.12) for the repair of my old vintage Yamaha HiFi Preamplifier (C2A) and Powerampl. M2and discovered this, possibly dangerous (fx. if a Poweramplifier is connected) , behavior.If any of you has a Siglent SDG5082 or perhaps one of the series 5000, maybe you can try this for verifying:Setup CH1:Load 50 OhmFrequency 1kHzAmplitude 0.5Vrms (dont type in 500mVrms!!!)Then turn Output CH1 onThe Oscilloscope shows (if terminated with a 50 Ohm resistor) 500 mVrmsThats good :-)Now press the CH1 key and CHCopy CH1=>CH2, then Done.Both Channel on the scope shows the 500mVrms 1Khz SineAll is fine, well done Siglent ;-)Now do this: (better change your scope input Ch2 to fx. 2V/Div)Change the Amplitude from Ch1 , type in 500mVrms, (not 0,5Vrms!!!)then press on the CH1 key, press CHCopy and then Done and you will get this (imagine if somthing sensive was connected) :FULL VOLTAGE/POWER ON CHANNEL 2 WILL APPEAR!!3.535VRMS instead the choosen one..That is really bad Siglent :-((Maybe someone can confirm this behavior and report this to Siglent.... and please, in case of a new Firmware, create an automatic synchronous mode for channel 2. It is very annoying to press a lot of keys, if you make a change in Channel 1, and have to hold them synchronized...I have tried to contact them, but this isRegardsTorsten

content: Welcome to the forum.Thanks for this info, it will be passed to Siglent USA.You're right, this shouldn't happen but I don't have a 5000 series ATM to confirm it.You say you have tried to contact them.....Who?

content: Hi tautech,many thanks for forwarding my e mailI have tried to contact them here:http://www.siglent.com/EU/Customer.aspxBut Siglents Websites are, like there Siglent Easywave (Windows XP??), poor... Maybe they should take some looks at the Rigol Website(s).The userinterface SDG5000 are, let us call it, poor too . They should take a look at Rigol, much more intuitive. (sorry for my english)Kind Regards to NZTorsten

content: Hallo Siglent,thanks for the reply.What do you mean by "the website which you visited is obsolete"?The Site is still there and is working/responding... (Checked via WHOIS, is located in Shenzen,http://www.siglent.com/EU/Customer.aspx)I have just checked out thehttp://siglenteu.com/Site , used a Nexus10 Tablet (Android 5.1.1) with several Browser (Google/Opera/Dolphin) andThis Site is not usable...with a Tablet... all upper menu item are not visible (Home,Product Center, Service........) ... that´s is annoying.But much more worst is:if i am looking, on the Mainpage, Latest Firmware & Software, SDG5000_Update, I see this:SDG5000_Update : Current Version: 5.01.01.10 | Published?2014-09-26That's not inspire much confidence.. Should be 5.01.01.12 ??Regarding the next Firmwareversion:Please create an automatic synchronous mode for channel 2.It is very annoying to press a lot of keys, if you make a change in Channel 1, and have to hold them synchronizedKind regardsTorsten

content: Siglent European side :http://siglenteu.com/gjjrj.aspx?id=15&page=2there isSDG5000_UpdateCurrent Version: 5.01.01.12 | Published?2015-03-10 (Download)And this Download link is:http://siglentamerica.com/USA_website_2014/Firmware&Software/firmware/SDG5000-V500R001B01D01P12.zip(also available is old 5.01.01.10 history version)Using IE 11 (11.0.24), Firefox (41.0.2), Chrome (46.0.2490.71), no problem.But as FW need develop, and I'm sure they do, also web sides need some fixes and developing better. As all need. Also my car need develop better and my car service web sides need urgently develop and they are "made in germany"-- simply - all need develop better and no one is never ready - never.There is many things in SDG5000 features what can develop better but also some bugs what need fix. As you told of course also this quite serious class bug. But also example how cursor "jump" or "stuck" when do adjustments. (etc)I'm sure Siglent listen customers. I can see they have developed themselves lot of in short time and this process is just started and continuing. Road is not easy.

content: Hi rf-loop,hmm., do yo have these Browser available under Android 5.x.x ?As I wrote I often use my tablet for surfing, like many others these days...and here is the pointYes, I also know were I can found the latest firmware, but why is an old is showing on the mainpage.....another pointImho, all these points, including the different Websites, leaves an unfavorable impression of Siglent.Yes you are right with the development of firmware, it takes time and nothing is perfect. Maybe they can clear off the delay of the cursor while typing in the next version.BTW. I like my SDG5082, is like a (unpolish)Gem

content: Well gentlemen....I punted the new firmware into my 5082 and was unable to 'selfadjust', getting the message 'Calibrating channel delta failed'.I then had 5vdc at the output of channel one, with output switched off.Took it back to the previous firmware and now have 1vdc at the output, but still no self cal.Any suggestions on how to get my box of tricks back to normal?Many thanks.Peter

content: Mr. Tautech,I went from 5.01.01.10R1 to 5.01.01.12 and back again.Initially saw the scope trace disappear to the top of the screen (with output switched off), so stuck a Keithley 2015 in the socket and got my 5vdc.High impedance out at 5vp-p, but not activated.If only I could get the self cal on the go, it might behave.Peter

No self cal fix.If the service manual provided the 'scripts' it alludes to, I might have a chance of getting to the bottom of it.Anyway.... thanks for the help.peter

When we find this issue ,The P15R1 is in testing for releasing."So there is still hope that this error is eliminated in the next firmware....It's all a matter of time
