content: Quote from: tautech on December 07, 2020, 07:45:54 pmWhat difference does it make that the Siglent models are 10 years old? The SDG810 and SDG1062X are still Siglent's current offerings.

content: Quote from: tautech on December 07, 2020, 08:02:02 pmThe one he uses is an SDG810. He has the SDG1062 (I didn't notice the lack of an X before) on his white board comparison. The SDG810 is still a current model.

content: Yeah as mentioned above check out the full thread on this. I have one and I'm very pleased with it but I don't use the AWG functionality, but it seams like the AWG function isn't the best, with the software being bad, and the fact that it loses the waveform when powered down.

content: I really not like the 20ns rise time... on the other side, for example, the psg9080 have an r-2r dac that i would non consider. And i wouldn't bet also on the fy6900 (as i have one, full modded). Every of this devices have it's shortcomings, seem that it's impossible to do a good and cheap device...

content: Quote from: masterx81 on December 08, 2020, 09:20:16 amexternal circuit consisting high speed comparator or jelly bean transistors is very easy to assemble if you want fast rise time. otoh good user experience in using the FG cannot be replaced with anything else other than what already provided out of factory, without modding it extensively, even require FW changes etc, in short building our own FG from scratch

content: Quote from: Mechatrommer on December 08, 2020, 09:37:35 amIt's not a pulse generator.If you hate that then youreallywouldn't like the steppy sine waves if it didn't have a low-pass filter on the DAC output...

content: Quote from: Fungus on December 08, 2020, 10:17:44 amOn the fy6900 (4ns rise time) on 5vpp sine i start to see the steps under 5khz. I think that on the utg will be much lower.I love have only one device to do things 😅

content: Quote from: Fungus on December 08, 2020, 10:17:44 amif you follow the other thread. the synch output to synch sweep signal is 1ns rise time iirc... so if we need some TDR toy, we already have one ready...edit: here... 900+ psfromhttps://www.eevblog.com/forum/testgear/uni-t-utg932utg962-200msas-function-arbitrary-waveform-generator-220394/msg2927402/#msg2927402
