content: OK first post. My old Farnel psu is iffy. Fancy the Rigol DP832A. Have all the probs been fixed? Don't want to spend around 450 of the brittish pounds if no good. Dave's live cam is not much good to us folk who are on tother side of the globe.

content: Why not the DP832 (without the A)?Only £258 and great value. Same specs, just different graphical user interface.

content: Quote from: josem on June 11, 2014, 09:21:40 pmI don't believe they have the exact specs. The 832 has a resolution of 10mV and 10mA and the 832A has 1mV and 1mA resolution. You can add this on to the 832 as an option with the extra I/O that the 832A comes with standard. Also, the GUI is different on the 832 vs the 832A as you have already mentioned. If you are not in need of the 1mV/1mA resolution, the I/O and the GUI then the 832 would be fine.

content: The 832A actually has the GUI of the Dp832 as an option (minus the 7 segment font). You don't need to use the crappy 3 position radial thing.

content: I have the 832A. I haven't had any problems. The only issue that is still there that I'm aware of is the voltage spike when you turn it on. So don't hook up your leads before you power up the PSU.

content: The spike doesn't look real big but if Rigol is listening (which is kind of hard to tell sometimes) they should fix it. Seems like they fixed other things and they should knock out the turn-on spike and then the product would be like their 1000Z and 2000 series scopes - no brainer clear winners at their price points.

content: Digital Version 1.09, display menu has "Classic" as an option, which is a close analogue of the DP832 display.There are also some pretty whacky options, like Dial. The waveform display is sometimes useful though - too bad it takes a menu to go to it.

content: I don't see "Classic" as an option on mine. But I'm on firmware 1.06. I should probably update this thing. Unless someone knows a reason not to?

content: I don't see that option on mine either. I have V 1.06 too. I went to Rigol's website and they only seem to have a "Request Firmware" option where you send an email. This seems kind of strange, why not just post the firmware upgrade?

content: Quote from: Legion on June 12, 2014, 12:20:03 pmWhat I've seen is that unless it fixes a mayor issue they don't want you to upgrade the firmware just in case you brick your device.

content: Quote from: miguelvp on June 12, 2014, 05:37:23 pmI can understand that. I talked to Chris at Rigol today and he kindly send me a link for the upgrade, took all but 5-10 minutes and I now have the classic interface. It also seemed to fix a few other little bugs I noticed too. I really like having the classic interface in 3 different colors. It makes it easier on the eyes than the monochrome single color screen.
