Hi, I've seen the Rigol DS1054Z now sold with all options unlocked and it costs about 120 Euro less than the SDS1104X, do you think that the Siglent is still a good buy?
Of course there is a gap for the BW (50Mhz vs 100Mhz) but I don't know if this difference is worth for the price, for hobby use.
The Rigol is easy to convert to 100MHz bandwidth, just press the right sequence of buttons on the front panel.

Greetings to all of Brazil. I use Google translate. I am an old reader of the blog. As a hobby I am a ham radio. Now I decided to participate and ask questions. Soon I want to buy a Digital Oscilloscope, I already had a Hitachi analog oscilloscope, 35 MHz. It was a "disappointment to children's fault" of the "probing" of the SDS1202X-E and SDS1204X-E. It seems to me that in model SDS1202X-e the problem has already been solved. On the question of SDS1204X-E how is the solution?

Siglent Technologies has kindly lent me their new SDS1204X-E oscilloscope (200 MHz, 4 channels) to help the lxi-tools open source effort
I hooked it up, calibrated the 4 included probes, and after enabling the network interface (DHCP) it was easily discovered with lxi-tools.
It turns out that this is an absolutely blazingly fast scope, especially in terms of LXI/LAN SCPI command processing performance!
With the benchmark feature I'm getting ~300 requests/s via TCP/VXI11:Code: [Select]$ lxi benchmark --address 192.168.1.125
Benchmarking by sending 100 ID requests. Please wait...
Result: 301.5 requests/second
And I get ~600 requests/s via TCP/RAW:Code: [Select]$ lxi benchmark --raw --address 192.168.1.125
Benchmarking by sending 100 ID requests. Please wait...
Result: 598.9 requests/second
This is quite impressive. Compared, the performance of e.g. the Rigol DS1054Z is ~30 requests/s via TCP/VXI11 and ~160 requests/s via TCP/RAW.
Of course, the faster performance is to be expected from a newly released scope which clearly uses a newer and faster chipset. However, fact still is, it is very fast and it is one of the first low cost scopes that makes it possible to easily implement a poor-mans data logger using LXI/LAN polling that can consistently sample data at e.g. 100 Hz or more.
I also notice that Siglent uses standard LXI ports as defined here: http://www.lxistandard.org/About/LXI-Protocols.aspx
That is, the available network ports for the SDS1204X-E are:Code: [Select]$ nmap -p- 192.168.1.125
Starting Nmap 7.60 ( [url]https://nmap.org[/url] ) at 2018-01-08 15:18 CET

918/tcp open unknown
5024/tcp open scpi-telnet
5025/tcp open scpi-raw
Nmap done: 1 IP address (1 host up) scanned in 40.14 seconds
In particular, they use standard port 5025 for SCPI/RAW and port 5024 for SCPI/telnet. This is one of the odd things that Rigol fails to do for the DS1054Z (they place it on non-standard port 5555):Code: [Select]$ nmap -p- 192.168.1.210

Taking a screenshot with the SDS1204X-E is very fast too:Code: [Select]$ time lxi screenshot -a 192.168.1.125
Loaded siglent-sds screenshot plugin
Saved screenshot image to screenshot_192.168.1.125_2018-01-08_15:37:22.bmp
real 0m0,361s
user 0m0,006s
sys 0m0,026s
Only ~0.4 second!
It's also nice to see that the Siglent scope has a small and light form factor which feels solid.
My first impressions are good - I'm looking forward to more testing with this instrument during the development of the GUI frontend for lxi-tools. It will also make a nice addition to the pool of instruments that I plan to use for lxi-tools performance and regression testing.
I have bought this scope and I love it, but I think I just discovered a bug, which happens in Normal trigger, run mode.
If you need the precise config files to replicate the issue ask, I can post them!
What do you think?
I had to go back and update the benchmark performance numbers for the Siglent SDS1204X-E because it turns out my network routing tables were messed up so all tests were performed over wifi - arrghhhh!
Over cabled network it's not doing ~300 requests/second.... It's doing ~1100 requests/second!!!!
Bam! Thats almost as fast as a Dolorean in overdrive!
With such result there is plenty room to make a poor-mans-datalogger sampling maybe several values at e.g. 100Hz or more.
Oh, and the screenshot live view feature in lxi-gui is now even more smooth hitting about 7 frames/second.
I captured a video instead to capture the time correctly:
https://raw.githubusercontent.com/lxi-tools/misc/master/lxi-gui-benchmark-live-view-sds1204xe.webm
It demonstrates the benchmark and live screenshot feature on the SDS1204X-E. It feels quite responsive.

mmm, my unit is already on 7.6.1.12 from the box.... Maybe it will update the FPGA bitstram? Is there any indication of the FPGA version in the update?

I'm bit surprised.
I do not remember if Siglent have done this any time previously - publishing first launch time FW version as update.
Or is this "Happy New year" present for.... due to chinese new year soon.
Perhaps - or is it just only dreaming - there was SDG2042X, SSA3021X, SDG1032X... is this next "wow"...
Least now some peoples have file what can "study"...

Yes, it's the same version Siglent sent me pre-release.
Not the first time they've put the wrong version online................
We'll find out what's going on tomorrow !

Software Version: 7.6.1.12R1
FPGA Version: 2017-12-18
Hardware Version: 00-03
Not sure what the R1 signifies?
No false alarm this time.
