Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China

Interesting behaviour when decoding is active..
Had tried SPI and RS232, after a few annoying moments I had it running.
Then I wanted to test up to which time base length the signals are still decoded (packages).
Ended with a little surprise... ;)
(forget it, roll mode was active..)
Martin72:
Decoding, continued..
For the siglent, RS232 at 50ms or more are no problem, it decodes and decodes and decodes...
Setting were quickly done and when you press "copy to trigger" all become rock-stable...very cool.
The rigol got a button "copy trigger", but it is not clear what will happen when pressed, it doesn´t act like on the siglent.
Apart from that I like the table design of the rigol more with it´s black&white display.
Moving the windows is a cool thing, but not intuitive to use.
In summary, the siglent decodes more stable.
Pics: Decoding RS232, SPI, etc..

You have to put Roll to off. (from Horizontal settings menu)
Martin72:
Ahh....
Didn´t notice the auto roll mode starting at 50ms... |O
Thanks !

The very last of today...
Copy trigger (decode mode): On the siglent it is obviously (copy from trigger, coppy to trigger), see pic.
Then measuring in general:
First I like the arrangement very much, you tap on the measure window and get a short menu on the left side - really cool :-+
But there´s something really annoying with it.
You couldn´t change the measure parameter in it... :P
You have to add a new measure window or remove the "old" and then add one with the wanted parameter, that´s really uncool and something for the wishlist to change.
The demoboard got some signals not only decoding types, runt, glitch, pulse, burst, etc.
Tested all, no issues with it.
And then there is a signal "noisy pwm" for demonstrating the Eres function.
Works perfectly on the rigol.
After all testings I´ve started to measure the update rate, will try to finish it before I must send it back.
What I´ve seen so far is, that the updates are always in "packages" regardless in which acquisition mode the scope is.
Or it is simply updates with "long" blind time inbetween.
The maximum I´ve measured was about 500000 wfms/s, will try it again in one of the next evenings.
Time is running out, can test something else until next wednesday evening, on thursday the scope will be send back.
Edit: BTW, in this time of testing the scope hangs two times.
First the screen becomes dark and a white windows appears with the request to start the "rigol app" again, the second I´ve already seen.
Scope was starting automatically after plug in the mains, boots and then freezes, the power button lit orange.
(Red = Stby, green = on)
