--- Quote from: psycho0815 on October 17, 2013, 03:29:17 pm ---Nah, believe it or not, but dave's not a factor here. The overheating issue with the rigol seems to be fixed. I don't think anyone has actually tested yet, whether or not the overshoot issue is still an present in the newest rev. As for the siglent fix. I don't want to solder in some bodge myself. I want the manufacturer to fix it. So if i can find a retailer, who can guarantee to deliver the newest rev. without the issues than maybe. Also: I really don't like the fact that i can't set a current limit on the 5V channel. I know i can use ch1 or 2 at 5V but still. Just doesn't seem thought through. Also i want a number pad. I like knobs as well as the next guy, but i like being able to just punch in a value, too. It's digital anyway so there's really no excuse. Especially for stuff like the timer it would be alot more convenient. Sure the keypadlayout on the rigol is ridiculous, but at least it has one. All that said, a 3 channel psu is more of a want than a need for me anyway so maybe i just wait a couple months and revisit the market than to see if the newest revs. ironed out all the kinks on either unit. --- End quote --- So psycho, which power supply did you end up getting? And what do you think of it? |

So to recap, before I ask the Siglent guy, the issues were: - Spikes / overshoots on CH3 during power on / power off - Spikes when the output of CH3 is shorted Have I missed anything else? |

Right, these were the problems. And a minor usability problem: when setting the voltage, you can either adjust it in 1 V steps, or with the "fine" button in 0.01 V steps, but not in 0.1 V steps. Maybe they have a new firmware which fixes this (my firmware version: 1.01.01.01.05, hardware version: V1.1), I made some suggestions like pressing the fine button longer for 0.01 V and short for 0.1 V steps, because at least for my applications usually I need 0.1 V steps. |
