Despite the fact that this is the only scope I'm aware of that does not maintain probe compensation when changing vertical gain,
Does my CML+ count.

Siglent America claims that it is in specification; specifically they said in an email to me...
We are familiar with the probe compensation issue. All of the SDS1000X-E products are in specification. There is no specification for “probe compensation flatness” between ranges.
I suppose you could argue that for a half-screen-height waveform, the HF response being within 3.5% is in spec. problem is it's -3.49% on one Y range and +3.49% on the next!
I guess you meant sds1104-ex, right? I don't know if some of this problem is the reason a lot of these models are on backorder now. This is the second thing I see Siglent mishandling in customer wise treatment. I was ready to pull the trigger for this model, even considered the more expensive model, but this really have me thinking. I do not want or care to go into a back and forth with Amazon over serial numbers, or even to have to call Siglent and be told that they are going to send capacitors and if I damage the motherboard by their omission, my warranty is not valid anymore. Whatever I buy now have to last.
How many times this need..........
SDS1202X-E old version have this problem as just told. And told many times.
I have repaired some SDS1202X-E models (BA) and also I have here also BB version and this version do not have this problem. Problem is also well documented and very easy repair. Just same as we have old times repaired many Tek and HP equipments after factory have published some recommendeds mods.
If model is serial prefix BB or later do not need worry.
Back orders... why you think there is problems in these equipments because factory can not supply as much than demand...
Do you remember when Riglol 1000Z come to markets... I remember. All sellers sell "we do not have" equipments. It was even some times unknown how long time perhaps can get. Problems in equipment or what was reason... time ago (some year) I buy some GPU's but I did not ask if there was some problems in these GPU's because I need wait 2-3 months.
Siglent factory was also ago all closed due to most big holiday time in chinese year. (yes bit bad time for this product time table in markets) In this vacation time they did not produce or ship any single item from factory in Shenzhen. As can guess (if never visited in any kind of factory) after vacation it also takes some time to starting up whole production to full capacity including all third party suppliers for some building blocks and components - as can guess. Also these models have just short time ago started and some places demand exceeds availability.
Perhaps this text was too complex and long... shortly:
SDS1202X-E have been this issue in serial prefix BA some manufactured lots.
SDS1202X-E serial prefix BB and later do NOT have this problem.
SDS1104X-E do NOT have this problem. (4 channel models are more new than 2 channel X-E models)
SDS1204X-E do NOT have this problem.
SDS2000X serie do not have this this problem.
SDS1000X and X+ models do not have this problem.
Older models, example old CNL, CM, CFL and CML and then its facelifted version CML+ have nothing to do with these new models exept that also they are mfg by Siglent. Totally different animals.
