The obvious thing to check is that the SPI is triggered on the correct edge, but looking at my data it is clear I have the correct setting for that.

I no longer have my DHO1000, but I seem to recall that there are separate settings for the clock polarity in the Trigger and in the Decoder settings, respectively. You have only shown us your Trigger settings in the screenshot. Might it be the case that in the Decoder settings you have told the scope to sample at the rising clock edge, i.e. just when the data line changes?

I keep returning to this thread with an increasingly forlorn hope that there'll be a spectacular firmware rabbit pulled out of a hat at some point, making my DHO924S more than a desk ornament one day.

Should I consider this scope a write-off?

have you purchased siglent sds800x-hd and LA module? since iirc your job is mainly LA, so i hope you can make comparison how far off dho900 compared to sds800x+LA. and i think your life need to move on rather continuously depending on crippled dho900 as i understand your situation from previous descriptions. but for us who dont really depend our life on LA (serial nor parallel) serious work, we hope there will be FW fix in the future. so we will put our dho800 in box for a while since person like me still have DS1054Z to work with. and since they are so much affordable now like smartphones, if i'm going crazy, i'll get one sds800x-hd to try, or even to use it as main bench scope if its really that good, ymmv. (the problem with sds804x or sds824x is they keep disappearing (out of stock) from aliexpress when i want to look for them)

me too, it's very disappointing that Rigol has not published a DHO software update for almost half a year now :--

I have some direct contact with their support. every time I asked "when" they simply replied "It's not scheduled but we are working on it" (and I just asked once again yesterday). by contrast, their competitor is updating firmware very frequently :-//

I do hear from some sources they are facing some human resource problems right now due to various reasons, mainly poor management.

Anyway, I will still keep my DHO because it is not that bad for my use case. I do hope they can release new software asap. :-BROKE

So I do already have an SDS1204X-E with the external SLA1016 LA pod, and I find the LA implementation to be a horrible implementation with plenty of functional and non-functional limitations. As far as I can tell, the SDS800X-HD has a very similar form factor to the SDS1204X-E, and uses the same LA pod.

It was the diminutive form factor of the Rigol DHO924S that I was interested in.

Here's a comment I made on the combo a few years ago about the SDS1204X-E and SLA1016 pod:

--- Quote ---Although this scope isn't bad, I have a couple of comments about the optional LA and AFG.

If you're thinking of adding the LA to make it an MSO, I find the LA on this scope to be very weak indeed. For an MSO at this level, I consider the older Rigol DS1000Z+ with LA probes to be a significantly better solution. On the 1104X-E, the UI performance grinds to a halt with the LA attached and it's a substantial extra package to carry about that can't help but take up bench space.

Similarly, the external AFG on the Siglent also is nowhere near as neat as the Rigol's internal dual channel unit, but you have to buy the Rigol's at the time of scope purchase.

So if you're only looking for a 4 channel scope only, the Siglent is definitely a better than the Rigol DS1000Z series. Just that I find the LA and AFG on the Siglent are rather disappointing.

To be fair I have more scopes than I can shake a stick at, it's not like I really need another one. However for field use, had the DHO924S worked out as anticipated and advertised, it would have found its way on trips. In recent times I've found myself making do with the Analog and Digital Discoveries for field work more and more, with a scope becoming more of an exception. Carrying a portable monitor with me helps in that regard so there's enough screen real estate. The AD lacks in memory depth, with the DD filling in in that regard. I'd still prefer a compact fully integrated standalone MSO though for my field work nirvana.
