content: Hi there,Apparently the Siglent SDS2104 (NOT X) has a 28M point sample memory. I've seen some manufacturers be a bit naughty and measure it in bits, each sample is 8 bit and so you should divide by 8. Or it does some weird channel multiplexing thing and divide by 4 for that as well turning a figure where 28M bits is technically true to a much less impressive 875k point.Can someone confirm what it does please?

At that time webservers were not in Siglent equipment but you could control them remotely with the EasyScope SW via USD or LAN connection to a PC.They didn't have a GPIB socket although you could use the USB to GPIB adapter:https://int.siglent.com/article/detail-152.htmlFrom around here member Performa01 shares some fine posts about these DSO's:https://www.eevblog.com/forum/testgear/siglent-sds2000-new-v2-firmware/msg814790/#msg814790

content: Quote from: tautech on August 23, 2023, 02:51:10 pmThanks, I come from Lecroy stock (which I wont hear a word against!) but I would like a faster update rate and always more acquisition memory. I'd be willing to trade some accuracy (of oscilloscope displays I'd wager a lot that LeCroy stuff lies the leastbut sometimes I just want the shape!)I STRONGLY prefer open source stuff, any comment about whether you can control it over LAN? Most 'scopes support SCPI (or something like that) - if you've read one GPIB/RS232 remote manual you've pretty much read them all IME. Are they like that?
