- This video is a first look at the Siglent SDL1000X series electronic load - actually the SDL1020X which is a 200 Watt electronic load. I'll show how it works and use the Siglent Oscilloscope to show waveforms.
Let them know I sent you - that would be so awesome;)

Many thanks Eddie!!; I love seeing videos on how test equipment is used and or practical uses. I can't count how many videos are out there that showing pretty patterns a functional generator can create with an Oscilloscope (while interesting it doesn't help me understand how to use a piece of test equipment for a real world problem). I would rather learn how to use equipment to design a better circuit and or troubleshoot a faulty PCB.
rrowan327 Thank you - that’s great feedback! I appreciate you!
Sure beats using resistors like I'm accustomed to.. Great video appreciate it.
Yes it does;) Here's a new nice low cost electronic load: ua-cam.com/video/LDpy2cbqDLM/v-deo.html
@@KissAnalog thanks.
Thanks, Eddie! DC electronic loads are handy. Can't wait to see the next video.
Robert Calk Jr. Thanks Robert!
came for learning here eddie,, thanks alot . very help
You bet - and glad to have you!
Great video Eddie, nice approach to showing that load. I have literally just started out on designing and building my own - and when I've finished I'll be able to properly test the output of the switching power supply I built. Although it may be a bit of a home-built job testing a home-built job :) Still, it felt a bit chicken-and-egg when I was building the PS at it always struck me that a DC load is needed to test it. Anyway, nice coincidence that you're going to show that load with a switcher, I'm looking forward to that.
I really likely the Siglent kit - I have an X-E scope and an AWG - good quality and a good price. They look a lot better on the bench than the Rigol kit as well, in my rather subjective opinion.
Andrew Johnson Thanks Andrew - I appreciate you! I was hoping to get that video out today but came down with the cold;( It sounds like you are having fun! I was supposed to get a GW Instek load but they shined me:) I’m sure their demos are busy and I fall low on the priority list:) I do think Siglent is doing a great job.
Merci K.A.
De rein - and kiitos for watching:)
Instead of using the differential probe and current probe, couldn´t you just connect the analog I and V outputs on the back of the load to the scope?
Edit: Yeah, the outputs on the back are linear 10V outputs. So if you put the load to 36V range, 36V will give 10V on the back, so you have to put the scope on a (custom) 3.6x probe multiplier. Same for current, with a 5A range, 5A will equal 10V output on the back, so you have to put a 0.5x multiplier.
Great point! You could do this and then use the math on your scope to give power;)
Great channel. Curious why you'd use chose the Siglent scope not the GW Instek in this video? Yes, the load is a Signlent, But..? :)
Afrikaner Stoppelbaard Thank you! I haven’t used the Siglent in awhile and since Siglent was so nice and loaned this load to me - I thought I’d show their scope too. Plus it was on the lower part of my bench and easy to get to;)
Hey good job, keep on!!!!!
Fernando Lagomarsino Thanks Fernando! I appreciate you!
Your videos are awesome BTW.
Thanks so much! I appreciate you!
Hello. I have a doubt. do you know if it is possible to do the on / off remotely instead of pressing the on / off button of the equipment?
thanks
Great question Hugo! Yes, I believe it is. I'll have to show how to use the software to control this scope. The on/off button on the scope only puts it in sleep mode, so I would think the software could do the same thing.
Great video, well explained. The CP is great but I'm wondering can you control two of the three basic parameters (CC, CV, CR) simultaneously?
Thank you Haroun! No I haven’t seen a load that can do that. Is there a reason that you want that?
Also... On the Zero resistance button. Does a relay click? also, is the max current for zero ohms specified in the documents? I could not find it. Since it would not really be zero ohms there must be a point where it will open due to heating - what could it be. Are you going to tear into it? I really be interested in how they short the input
Thanks for the question, but unfortunately I had to return this as it was just a loaner.
Have you experimented with the OPPT (Over Power Protection Test)? I read the manual, performed some bench testing, but I'm still confused by it.
Thanks for asking, but I had to return this unit to Siglent and I never got a chance to test that function. Are you discharging a battery? I think the voltage has to be above a set value and then shuts down when the time meets the end of test, or the voltage drops below a set value.
Howdy neighbor :) Is it using mosfets for the load resistance?
Thanks for the great question! I think it is but I can only guess now as I had to return the unit. It was just a loaner.
Hi Eddie! When making these measurements, how critical it is to keep the wires from the DUT to the electronic load as short as possible? Does it affect slew rate? Part of me tends to believe that the leads' inductance may have an effect on what we see on the scope but another part tells me that since we are taking measurements right from the output of the power supply, we should be Ok. Thanks!
Great question! It is always a good idea to keep leads as short as possible, and use a nice gauge of wire. The slew rate usually isn't too crazy fast in these electronic loads. But that is something to consider and look for. The important thing is to think about the test and what might effect it. Inductance in a meter of wire probably isn't a big deal unless you are switching in nanoseconds or even in a few microseconds.
Very nice review! Will order one of these this week.
Was asking myself a question here: Could this DC load be attached in series with a Li-Ion cell where both the cell and the load in series are connected to a power supply.
Reason: charging the Li-ion cell with a certan amount of Amps in CC mode.
I know this is something you must monitor very carefully in order not to overload the Li-Ion cell but this woud be a good idea to test charge and discharge properties.
That is a great question!! I would think that with the power supply most likely having an isolated (floating) output, and the battery is floating too - that I couldn't see why it wouldn't work. Cool idea!
@@KissAnalog I'll let you know, will start with a LED attached to a 12V battery in order to feed it no more than 10mA where the DCload will act as a replacement for a 12kOhm resistor.
If it fails, I will have a miny LED flash!! light 🙃
Hi, I found the DYS function useful (for my personal use) I ask you ... you can set a program of about 100 cycles ... I need 100 load cycles (example 12v - 8A) for 1 minute and beteween one load and the other I have to set a 3 minute break (0A) ... can I do this?
Yes I think that is the type of thing that you can do. I had to send this loaner back:( I wanted to do more testing but I had to return it as it was just on loan. I'd ask the Siglent folks about any testing that you want to do before purchasing it just to be sure. Thanks for asking.
I really like that Electronic Load, but I can't afford it right now. It's $499 on Amazon.
Thanks - I know what you mean. I would have liked to have kept it but just a bit too much right now. It was a loaner and I had to send it back.
Hi Eddie, great video, I actually went and got one of these after i saw your video, albeit the SDL1020X-E model, works great! But i wonder, do you know if Siglent has any kind of tech support, wasn't able to find that on the pages i was looking at. Mine doesn't always come up with same MAC address when connecting to Ethernet, so it doesn't always get the same IP from DHCP, but i think that can be worked around by giving it a static ip, so no big deal... I'm trying to get it connected to Labview NXG, will see if that is possible, haven't found any driver for that yet.
Thank you - I appreciate you! You can contact Jason Chonko - and let him know that I sent you;) jason.chonko@siglent.com
Have you tried the voltage and current monitoring via 0-10 V output in the back?
No, but now I gotta give it a try;) I still have it because of this virus that's slowing everything down:( But I do need to return it so maybe I should do another video and check that port out. Thank you for pointing this out.
The siglent 1202x-e is a great scope so much faster and cleaner then my old scope. Now can you recommend a good low cost spectrum analizer .
What frequency band are you interested in? Thanks for the feedback, and I'm glad that you are enjoying your Siglent scope. Have you looked at the Siglent and GW Instek Spectrums? Check this one out:
amzn.to/2J4QVTx
@@KissAnalog 26,27,28 mhz
That's not too high in freq. so MHz right - not GHz?
@@KissAnalog up to 30 MHz
You don’t say anything
I’m sorry - what were you looking for?
