Why not a 914S + cheap diy PLA2216 (with SN65LVDS391 drivers) ?  you may save about a third of your budget

I think you just answered my next question: The PLA2216 is not totally passive, correct? It has some active components? 30 years ago, and I'd have DIY'ed that sucker in a heartbeat. ;)

Also, are you recommending the 914 over the 924 because I can "upgrade" it on my own? I'm happy to give them an honest $100 for the spec bump.

Thanks!!

To be clear, the DHO800/900 come with ASCII, I2C, and SPI decoding activated from the factory, i.e., no extra "option" to buy, correct?

I got kind of an equivocal response from my vendor.

Thanks!!

I'm interested in getting a new scope (currently use a 1054z) and am considering the 924S as the feature list looks so appealing.  I definitely want a segmented/deep memory mode to catch intermittent errors that I can't specifically trigger off, but I'm not sure from the user guide how this works on these scopes.

Can anyone tell me whether this has a "typical" segmented memory mode (like on the rigol MSO2000 series I can use at work), where I could fill up the memory with a series of waveforms, and then cycle through them one by one?  The user guide explains some interesting ways of displaying many signals next to each other, but I can't tell if I can select waveforms one by one, and ideally use the cursor or measure tools on them.

Thanks!

My interpretation of the datasheet and user guide is - yes, segmented memory is supported and Rigol refer to their implementation in the DHO as "Waveform Recording" and "Navigation".  The latter option allows you to step through the captured trigger frames, or jump to a specific frame number, and you can make cursor-based measurements when you're there.  "Ultravision", I believe, is just Rigol's tradename for some of the fancy visualisations that allow you to see more than one frame at a time, superimposed in a variety of different ways.  Probably fun just once, then you'll just use "Navigation", which probably works much like your MSO2000 (I've never used one myself).

You are correct, there are no "extra" options that can be purchased.

Whst is so cool with it? Now instead of one piece of gear taking space on the bench you have two. And have to care about maintenance (charging) of the battery pack. Did not have enough things to do, now you do.
