...make sure you power cycle the unit after fw update... just in case...
Thanks for the links, Tautech. I read through the updated manual and change log and will be updating soon.
Unfortunately it looks like the unit cannot produce the waveform that I want. if the channel combining feature had a multiply (VCA) operation then I think I could do it.
Still a great little unit though....make sure you power cycle the unit after fw update... just in case...Will do. Sorry to hear about your troubles, I hope you get that worked out. There should be an initial factory programming procedure that you can follow, assuming you can get hold of it.
I recently received my "Amazon Warehouse Deal" SDG2042X. Unfortunately, it has a problem starting up.
Often, it displays a black screen when turned on. However, if I turn off, wait about one second, and then turn it back on, it boots properly. If the wait time is too short or too long, it will remain on a black screen.
It was shipped with firmware 22, and has been upgraded to firmware 23. Otherwise, the unit functions normally. Rebooting works properly; the issue is only triggered when the power is cut.
My best guess is that there is a soldering issue of a decoupling capacitor somewhere.
If I break the warranty seal, is the warranty voided?
EDIT: Also, the unit came with a cal cert whole serial number did not match the unit delivered. Do other's calibration certificates have the proper generator serial number? Also, it didn't list the frequency reference used in the calibration, only a multimeter and a power meter.
Regarding the Cal cert........can I ask if the factory box had previously been opened ?
2 layers of tape closing the box is the giveaway.
I'm just thinking if someone opened some boxes of these and mixed up the manual packs as they enclose the Cal cert, little info like this can determine if it happened at the factory or later.
Anyways, it's faulty IMO and need be replaced so don't open it please. Continue using it until the factory recommendation comes through.
Thanks for pointing this out.

I purchased it "used" from Amazon. Someone else must have encountered the problem and returned it, and then Amazon thought it looked ok and resold it to me at a discount. It did not come in its original box, however otherwise it appeared new, with the screen protector still on it, in a heavy duty clear bag with silica gel, packed with a BNC cable and a power cable. The certificate it shipped is dated December 11 2016. Perhaps Amazon could have mixed them up? I don't know.
I just received my second SDG2042X today.
Overall a very nice device, but Siglent seems to have a little quality assurance problem at the moment.
Maybe I accidentally ordered a unit for inverted signals only
So in the new design, the feet are no longer feet. They are heads instead of feeds.
So in the new design, the feet are no longer feet. They are heads instead of feeds.We discussed this in some thread a while back, the feet/bumpers can be flipped but IIRC there was a small mod required to have the bumpers fit the case nice and snug in the flipped orientation.
The factory may have changed the rubber casting slightly to allow them to be flipped......this I haven't physically checked.
Edit

.... presumably if there are nuts that secure the screws for the rubber feet/bumpers those nuts would be adhered to the inside of the chassis so they couldn't fall loose while flipping or adjusting the rubber feet/bumper (and create a short inside the chassis), right? i.e., those nuts are captive, correct?
(If the nuts aren't captive it wouldn't make sense to suggest that users should flip the bumpers around without pointing out the potential for causing nuts to fall loose in the chassis).
Hi Gaurav,
My question I have for you is there or do you have access to the 178R5 fimware or earlier,
many thanks to "eevblog" 17R5
Connection with the LAN shows "network connected, problem" in Windows 7 x64. So I thought I cannot telnet it anyway.
