The frame rate and measurement speed of the SDS5000X series are simply terrible (~5000 frames/s with low memory depth)
The SDS plus should arrive tomorrow, on evening.
I´m exiting about the things it could do better/worse than my former owned rigol…QuoteThe frame rate and measurement speed of the SDS5000X series are simply terrible (~5000 frames/s with low memory depth)
Will check this.
By the way, "terrible" in comparison to what ?
Example: if you never use the CAN decoder, even if you switched the scope on for 100x, this functions still got 30 usages left?

It seems so - I´ve only used the AWG and activated the power analysis for looking what´s inside the menus.
And both of them have now "29" left.
The RTB2004 has only 300MHz bandwidth, but an actual 10bit ADC with 2.5 GSa/s (interleaved) and a higher resolution screen.
a SDS2354X PLUS with Logic Probe, Wavegen and CANFD decoder license comes in at 3549€ net.
Therefore, I compare always the basic models.
Memdepth : It´s manual selectable...
Memdepth : It´s manual selectable...That sounds very promising. Does it always stay that way?

Memory Depth: The maximum memory depth that can be supported.
According to the formula "acquisition time = sample points x sample interval",
setting a larger memory depth can achieve a higher sample rate for a given
timebase, but more samples require more processing time, degrading the
waveform update rate. With 250 Mpts memory depth, SDS5000X can still run
at full sample rate (5 GSa/s) even when set to the 5 ms/div timebase.
Note: The memory depth here is the upper limit of the memory space allocated
by the oscilloscope. The actual sample points is related to the current timebase
and may be less than memory depth. The actual sample points information can
be obtained in the timebase descriptor box.
The maximum (!) memory is selectable also for the SDS5000X, but the manual is a bit vague if you actual force the scope in using the maximum memory:QuoteMemory Depth: The maximum memory depth that can be supported.

For me this sounds a bit like the scope doesn't consider the maximum memory to capture data outside the screen but more like would only use this value to use a higher number of samples for what is shown on the screen. But I may be wrong.

Hi,QuoteNote: The memory depth here is the upper limit of the memory space allocated

For me it´s a normal behaviour, other scopes are doing it too.

On other oscilloscopes you can either set a specific amount of memory OR have the oscilloscope manage it automatically to maximise the number of waveforms/s. I've used over a dozen of different DSOs over the years and Siglent really is an exception if they don't allow to force a memory depth.
No. Keysight (the general purpose scopes) for example will always use the maximum amount of memory.

Maybe i got it in a wrong memory, but I saw it on lecroy and rigol scopes too.
First I can check tomorrow on work, the second was gone…
