Download speed from Rigol DS1054Z or similar oscilloscope to a PC
RoGeorge:
Asking because I've just tried, and it took more than 21 minutes to download all the 24 million data points. ::)
The PC can easily download from Internet at 700-800 Mbps, so the bottleneck is not the computer's hardware.
- Software: Kubuntu -> VScode (Codium) -> Jupyter Notebooks -> my Python scripts -> python-ivi -> PyVISA -> PyVISA-py -> python-vxi11
- Hardware: i7 Desktop -> LAN cable -> 100Mbps router (switch) -> LAN cable -> Rigol DS1104Z oscilloscope
Anybody else tried to download all the data sampled by a Rigol oscilloscope?
How fast does that worked for you, and with what software/hardware, please?
Fungus:
What format did you download it in? CSV?
Bottom line: The rigol is an oscilloscope, not a high speed internet device.

The bottleneck is the scope, not the connection.
Data needs to be downloaded in chunks of max 250,000 bytes.
Between those chunks there's a long delay in the response of the scope's firmware.
Why? Only Rigol knows...
Edit: I did a new test with the latest firmware (the one Rigol removed) and now the download time is 33 seconds for 24Mpts.

That was 8+ years ago. Back then I was experiencing very slow downloads, but only when using Windows. From Linux it was OK. I thought that issue was sorted out. Now, many firmware updates and many OS versions later, I'm seeing about the same problem, but with Linux. :-//
Anybody else tried downloading the data samples from a Rigol recently, please?

yes 30-60 seconds is the right figure to download raw 24Mpts data using visa driver from VisaDSO in Windows here.. if it takes 21 minutes for you, something is wrong.

We know nothing at all about how OP is "downloading"the data...
Karel:
Using DSRemote it takes exactly 30 seconds (per channel) to download the whole 24Mpts.
