| Carrington:
How many hardware versions are up to date? |

--- Quote from: Carrington on July 03, 2013, 07:15:55 pm ---Shortly after buying my SDS8102V was discovered the noise problem (HW). And now that I've bought a DS2072 if it appears that also has a hardware fault then ... :o :rant: |O --- End quote --- ::) I hardly think it's the end of the world. My Tektronix analog scope doesn't even have coupling choices for the trigger - and I can't say I've ever used AC-coupling for the trigger on a DSO yet. |

Yes you're right, "I hardly think it's the end of the world." Only I wish it was not a hardware failure. If it is, do not want to jinx myself, but lately everything goes wrong. Let us trust in the experience Rigol. |

Anyone have an image of the input stage of a DS2072? To compare with this (DS2202): http://www.flickr.com/photos/eevblog/8022205124/#in/photostream/lightbox/ SMD Marking: 6U -> MMBFJ309, N-Chanel RF Amplifier. 3E -> MMBTH10, NPN RF. 1B -> BC846, NPN. JY -> BAV199, low leakage double diode. B7A -> AD8510 Would be very interesting see the frequency response until the input of the LMH6518. And a schematic of the entire input stage would also be great. If there are "common desing HW" (inherited) between the DS2072 and DS1052E, then I want to believe that this failure is not due to hardware. :) http://elinux.org/images/c/c6/Das_oszi_schematic.pdf https://www.eevblog.com/forum/blog/eevblog-360-rigol-ds2000-oscilloscope-teardown/120/ |
