--- Quote from: diodak on December 12, 2018, 05:57:37 pm ---For me it was important information but I did not find it. Well, in the 30V version, the integrated circuits responsible for setting and reading the voltage and current are AD7782 and DAC8562. Unfortunately, I have no information on how to calibrate this power supply in the future... --- End quote --- They are a closed box calibration, in that PC scripts and a universal calibrator are needed to program the PSU's internal calibration settings. More info on this matter is available here: https://www.eevblog.com/forum/testgear/how-to-calibrate-siglent-spd1000x-spd3303x-spd3303x-e-series-power-supplies/ |

So I will wait for service manual ... I think that the calibration will not be particularly difficult. Probably like in other devices, i.e. based on two voltage and current points. Possibly, there may be a zero offset. |

It would be nice if they enumerated the bugs they actually fixed in the release notes rather than just "fixed some bugs". I haven't noticed any buggy behavior on my SPD1168X's really, but I guess I'll update them anyway. :-// Update performed, no problems. |
