Siglent SDL1000X/SDL1000X-E Electronic Load
Martin72:
When I requested the "uncut" manual from Siglent, I received it straight away, presumably because I am in contact with the support team at work and they know that I won't tell them off if a calibration goes wrong. ;)
Because there had been problems in the past, so they decided to remove the part from the manual.
I also can't imagine that Siglent only assigns staff to make the procedure "fool proof".
In other words, it will remain as it is now, without calibration instructions.
I could look into it and create a more brain-friendly manual, but I would need time that I don't have, because there are already too many "projects" in my pipeline and such a calibration would definitely be low priority.
In addition, I personally only trust displays from external measuring devices anyway and never rely on the internal displays of loads/generators/supplies.
This is also how "my" test field is set up at work.
Oscilloscopes, multimeters, power analyzers, data recorders, current clamps and differential probes are calibrated, everything else is not.
I "turned" my 1020 into a 1030 last and saved a lot of money and I'm not the only one who did that.
So you could go along and spend some of the money saved on an external calibration.
Because the guys from a measuring laboratory must be able to do this, they not only get the specs from the manufacturer, but also calibration instructions if available.

@Tautech -- one request to Siglent: Please add support for the SCreenDumP (SCDP) SCPI command to the SDL1000X. I was rather disappointed to find it missing from the programming guide.
The odd thing is that when I send the command, I get a success code, but then 0 bytes are returned. I was hoping that, like with the SDM3065X, it might be an undocumented command.

@Tautech -- any update on this feature request? I wish to use the SDL1000X to document battery capacity and discharge characteristics. I would prefer to just grab a screenshot via SCPI of the final results rather than having to either taking a photo (ugh!) or dumping the raw data and plotting the results. Lack of screenshot capability in any modern piece of test equipment is just bizarre.
Second request -- on the battery discharge screen, please show total power in mWh, along with the mAh. I am trying to test a battery with a non-linear voltage curve when discharged at a constant current. Having the instrument do that calculation for me would be helpful.

For another thread (looking for a current clamp), I finally used the load. :-X ;)
Oh dear, the DC current has a ripple superimposed on it.
Closer examination showed that it is a 100Hz signal, i.e. a mains ripple, that somehow interferes with the generated current.
To rule out the connected power supply as the cause, I had ordered a 12V battery, which arrived yesterday.
I connected it earlier today and lo and behold, the current remains unchanged, the ripple remains, so it is definitely due to the load.
I will investigate this in more detail soon, to find out where it comes from and how it can be reduced or even eliminated.
User nctnico had already done excellent “preparatory work” in this regard, as he noticed something similar with his DC load.
I'll check this out first, because the transformer from the Siglent load is mounted at the front, its lines are routed over part of the circuit board.

Now I received SDL1020-X from China.
输入端子透明防护罩(上壳+下壳) [Input terminal transparent protective cover (upper shell + lower shell)] were added to the kit. There is not a single image of this detail on the Internet.

It would be nice if Siglent could provide the files to 3D print it ;D
