Siglent SDL1000X/SDL1000X-E Electronic Load
blackdog:
Hi,
For anyone wanting to buy a Siglent DC Load and use the measurement outputs on the back, these measurement outputs almost are unusable.
I have heard through word of mouth that Siglent themselves are not happy about this either.
I therefore sent the Siglent DC Load back.
But, the Rigol in the same price range is not much better.
It too has problems with the measurement outputs on the back.
If you connect a battery scope to it(floating), which is therefore not connected to the Net ground, then these outputs usually oscilate!
Connecting the battery scope to the mains ground solves this problem, or a capacitor from the BNC connector to ground of the DC Load.
Great job Rigol, and very well tested too!
Also, I have the Korad model.
The Developer who made the interface is probably on drugs.
I made some lists on how to set certain functions for the Korad, but one mistake and you can start again from 0 with many button presses.
The DC Load Brands/Models I have held in my hands, do not seem to use a real DAC, but probably PWM, so the noise level is high.
Good measurements in terms of dynamic behavior on linear power supplies is therefore not well possible.
For this I now again use my self-designed DC Load, which is free of noise and other undesired behavior.
I had hoped with the built-in test functions of modern DC Loads that I could also do good and fast measurements on all kinds of power supply circuits.
That was not possible with the Korad, Siglent and Rigol.
With the prices of these devices between 300 and 800 Euro.
Not to mention the software bugs in these units, with emphasis on Rigol...
Just try setting the Duty Cycle in percentages, have fun!
Kind regards,
Bram

Turned on my SDL1020X-E. It looked fine when it booted. The I went to get a cup of coffee .. maybe 3 minutes later this is what I now have:
It has suddenly got all these white horizontal lines on the display. Turning it off and letting it cool down overnight did not do any good. Leaving it on overnight to fully warm up did not do any good.
Is this something that can be fixed with a little adjustment or is this a return to Siglent thing?

It is surprising how many manufacturers manage to mess up a device that has a relatively simple function so bad. According the reviews, you can add Keysight to the list as well. I have not checked expensive loads from Chroma and GW Instek (and other brands) though.
@BillyO: looks like a return for a warranty repair to me. If you have no warranty, maybe it is something simple like re-seating the cable to the display.

I was thinking it might be something like that, but I do have warranty. However, the cost of return will be high. This is Canada and it's heavy. Plus I'll have to do without it for a couple of weeks.

Contact NA and seek advice.
As Nico says it could be a ribbon cable contact issue but FWIW the last section to the display is a mylar flat cable with embedded components which if faulty will require display replacement.
