New Hantek DSO2X1X models?
eurotips:
I saw somewhere on cxem.net a conversion to a linear power supply. There wasn't much difference. Maybe Hantek improved the quality of the built-in power supply.
Maybe it will heat up less at +/-7V. Anyway, I added heatsinks on the ADC, FPGA and F1C200.

I think so too, because noise is not an issue with my version.
If it was less noisy at 2mV/div, I would think it had crashed. ;)
In any case, I wouldn't think of trying to improve anything in this area.
Aldo22:
I have just looked at the DSO2000 specs again.
--- Quote from: DSO2000 Series User Manual ---Overvoltage Category: 300V CAT II
Maximum Input Voltage:300VRMS (10X)
--- End quote ---
What does this mean: "300VRMS (10X)"?
30VRMS @1X?
That would be less than what the Zeeweii can handle.
Really?
Aldo22:
Does nobody really know how many volts the Hantek can withstand on the BNC?
I'm not at all concerned about my safety as I don't work with mains, I just want to know whether I'll damage my scope if I have 40 volts on the alligator clip or the 1x probe, for example.
Should I ask in the beginners' forum?
I've read some stuff but I'm not quite sure if I understand it right and I want to be sure.
Somehow there are different aspects and I don't know exactly what the values refer to.
- CAT rating seems to be more for the protection of people.
- The maximum the scope can display (10Vpp x 8 in my case).
- What can the probes withstand? (600Vpk x10 and 200Vpk x1 in my case).
- What interests me: At what voltage on the BNC will my scope be damaged?
While the description of my scope only says this:
--- Quote ---Overvoltage Category: 300V CAT II
Maximum Input Voltage:300VRMS (10X)
--- End quote ---
the manual of another Hantek scope says something similar, but with an addition:
--- Quote ---CAT I and CAT II 300VRMS (10×), Installation Category
CAT III 150VRMS (1×)
--- End quote ---
So the answer could be 150Vrms?
Thank you!
nycn:
Received my new new DSO2C10. Added some components from brocken premium psu:
x and y capacitors right on power socket, ferrites - the ring near switch button and clip-on ferrite on +-7v flat cable. Also added copper shield to the transformer.
2mv high frequency noise level was redused in about 2 times.
