| New Hantek DSO2X1X models? |

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. |

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. |

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? |

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! |

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. |
