Rigol 1052E Partially broken at arrival

Post by JoannaK »

I did send E-mail to Adafruit support some time ago (17th Jan) , but apparently it never reached anyone even half qualified to answer. So I have to log here and send info on this forum with hope I'll reach someone with brains for a change.

Yes.. not really happy with the service (or lack of it) but.. well.. Back to the issue at hand. I'm not going to add all the attachments here, just screen captures. Also I did shorten the message somewhat.

Hi.

I received the package (invoice 409149) last Friday and have been going trough the goodies. When testing the Rigol scope 1052E I noticed that the long memory seems not be working 100% ..

I have included some screen captures and waveform files that show the issue. These are taken when both channels are connected to Probe calibrator signal. Pics 0-3 are taken with 2 channels active, and last two with just channel 1 on.

Apparently what I can see, about every 1/4 th of the samples has some corruption issues depending on incoming voltage level. If there are 2 channels active, the problem is always on channel 2.

As far as I can guess without opening the scope there is lose solder joint on 1 data line (at the external ram or the FPGA?)... I'm quite sure the problem is not at the AD converters (or analog front end) since I have seen no problems with normal memory modes.

I assume you've tried swapping the probes to see if it's just a bad probe?
Try emailing [email protected] again this time with a link to this thread for a replacement scope.

I really don't understand how having this forum post will help you now, since you got my email two weeks ago...

PS: If you had looked the problem description (screen captures) and have some skill with electronics, you'd see quite fast that this kind of error ain't happening due bad lead.

Edit: For the record, I'll mention here that I have now send my E-mail again. Alongside the first nonreply-reply I got from Adafruit support.
