- Adding trigger mode "Alternate" if possible
This is, how I can say it enough nicely... yes of course we can write to SantaClaus many kind of wishes... and so on.
But honestly, if we want in 4 channel scope true full Quad independent timebase Quad independent trigger "Alternate" I believe simply, this gift do not come never to any already purchased Siglent 4 channel scope. And I believe also that not any future models... If drop independent timebase and think only single timebase individual triggers Alternate, not so hopeless wish technically... but, forecasting is difficult - especially to predict the future.
If 2 channel is enough and so that both have own memory and own ADC chip as is case when SDS2k works in interleaved mode, perhaps independent Alt is bit more easy..
Least I know some use for this feature but also can live without. For dedicated special needs mostly there is other solutions.
It is fun but Siglent have this kind of scope what have dual timebase alternate mode.
Old SDS1000CML/CNL.
These have. Both channels can drive with independent t/div and both channels have also individual triggers. So it can capture and display very very different signals simultaneously. One weak point is that both channels have same samplerate what is limiting factor for extremely different speed signals. Naturally if other channel have 1Hz signal and other have 100kHz signal also this 100kHz channel wait until 1Hz waveform is captured and then it capture this 100kHz signal... and continue alternatively, just like old single beam analog scope ALT works. (True dual beam analog scopes is Very different story, example Tek's 7044 where other trace trig do not need wait other...) Also both channels have fully independent trigger settings as also independent timebases (iIrr, if I remember right) and even both may have dual timebase, but these was old time analog oscilloscopes RollsRoyces (including price).
After old SDS1000 series various scopes it is not implemented in any other Siglent scopes what is sold as Siglent brand as far as I know.
Why exactly, I have no idea.
I hope Siglent take seriously this Alt feature, demand for this pops up repeatedly. It is not just sales brochure checkbox feature. It need be, performance and features (how does it work) of this mode is then other question.
