SIGLENT SDG1025 FAIL
« on: July 11, 2017, 01:27:40 pm »
Hello
The SIGLENT SDG1025 generates poor performance when changing frequencies.
Please watch this movie and write what you think.

Are your generators other than SIGLENT eg RIGOL having the same problem?
The information has already been sent to SIGLENT.
Now I'm waiting for an answer.

Regards
Christopher.

I never had such issues on my SDG1025. If it's a thing, mine has to go anyway, because I want one with lan.
I don't have acess to it, but I will look into the problem onve I have.

Gamma spectrometer works. Now some yellow crystals need regenerating and testing.

I haven't experienced this with my SDG1025 but I can try to reproduce it tonight. I do remember updating firmware on mine when I first bought it because it had some bugs, but I can't remember what those bugs were of the top of my head.

This is normal behaviour for many (if not all) digital function generators. If you need defined behaviour then use the burst function combined with a trigger.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

It is not normal. In RIGOL generators everything is OK

I use class C++

Code: [Select]
pseudocode
for(f=Fstart; f<Fend; f += delta){
    set_SDG1025(f);
    Sleep(100ms);
    measurement();
}

I need eg 500 samples.
Function measurement(); Shows nonsense.

No.

(Rigol DG1032Z here)
I told my friends I could teach them to be funny, but they all just laughed at me.

I think you must use the Sweep function to side step the frequency change glitch.
