Hello,

I have received my DS1052E today from DealExtreme. Looks like no hack for me at the moment. Details of my version below:

DS1ED125xxxxxx
Software: 00.02.05.02.00
DSP: 00.00
FPGA: 02.00
HardVersion: 58

Fingers crossed for the future.

John.

That is the same oscilloscope that I have at my room.  The only component shielded, that I see on the board is the input end dual input channels amplifiers.  The class of oscilloscope is less priced like those lower bicycles for us here in the U.S.A.  I never can afford the analog oscilloscopes by Tektronix, when I went to electronics school, before geology school.  I did noticed the DC output on the power supply has a ribbon cable without a choke.  Some power supply outputs have chokes inside computers.  I totally still liked it a lot and it is my only one.  I have no access to universities anymore, that I graduated from them three to four years ago.  I am sure everyone seen Dave Jones's tear down of the Rigol DS1052E.



The oscilloscope is good enough for my hobby in 7400 TTL and straingages, seismographs.  Here is the complaint about the DC coupling in the square wave output in the DS1052E, but no solutions on the problem with the slight AC component in the square wave form along the flat peak portion.

Today I noticed interesting thing about bandwidth vs internal attenuator on my DS1102E (hardware modded).
Internal attenuator switches on at  250mV/div (and greater), you can hear relay click.

Look at animated gif  ;)

Hi Lew, I have the Rigol DS1052E up modded to 100 Mhz BW. I just tried your problem on my scope and it behaved as expected. No change from DC to AC coupling. The firmware in my unit is 00.02.04.00.03 HW57.

Try downmodding and then up modding to this firmware level as this is supposed to be the best with no bugs. Also has the help files working. But before that try and do a "factory" reset via the storage key and load it to factory default settings. Perhaps your machine just needs to be reset.
