content: I'm on the hunt for a new desktop DMM, i'm looking at the Siglent Technologies SDM3055, just wondering if it does peak hold. I use this for testing amplifiers output and want to be able to put it in AC RMS mode and have the input go up and down and it show the "peak" accurately.Picture for attentionSuch a nice looking piece of equipment. !

content: What kind of accuracy is required? A VC8145 (4.5 digit bench DMM with a wide AC frequency range) may do the job and they sell for around $150.

content: Quote from: nctnico on October 28, 2017, 08:01:50 pmWell, im working on amplifiers so i want good quality, ill be doing dc rail voltages for pre & power amplifiers. I plan on buying to of the SDM3055's and soon a new scope.

content: Quote from: dashpuppy on October 28, 2017, 09:45:20 pmThat still doesn't really clarify the need for a 5.5 digit DMM. For example: I have a Keysight 34461A and two VC8145s (all bench DMMs). The VC8145s are my daily use DMMs because they start up quick, have instant continuity (not fast, but instant!) and have enough accuracy for general purpose use.

content: Quote from: nctnico on October 28, 2017, 10:59:59 pmCan you still buy Keysight 34461A's ? are they expensive ? Id be willing to use those if i can get a pair. I don't need 5.5 digit, but i just thought if im buying new Benchtop DMM's might as well future proof..

content: I have a 3055 and for the price I think it is a great buy. I really like the extra features like the trend chart which is handy to monitor a voltage over temp and such. I also have a Keithley 2010 DMM and the voltages pretty much track with my 3055 so I am confident that the readings are accurate.

content: Quote from: MikeLogix on October 29, 2017, 01:13:43 amWell I was looking at all the other ones mentioned and they were more money used. So I'll probably just end up buying a pair of SDM3055's.

content: Quote from: dashpuppy on October 28, 2017, 11:45:29 pmA Keysight 34461A is part of their newest range of bench DMMs and it sets you back about $1100 each (ex. VAT / sales tax and shipping). The slightly lesser model 34460A sells for around $950.I'm not quite sure future proofing is always a good thing. Personally I rather buy stuff when I really need it so it can start earning money straight out of the box.

content: Quote from: nctnico on October 29, 2017, 05:25:22 pmI'm just building my work bench and buying new stuff, the units you mentioned to me were more than the brand new one that i'm looking at. So to me buying the brand new better ones are cheaper and i'm better off.After i buy the two dmm's I'll be buying a new Siglent Technologies SDS1102X Scope..

content: Quote from: dashpuppy on October 29, 2017, 08:49:31 pmIf you're not in a rush the 4 ch X-E is out in a few weeks.https://www.eevblog.com/forum/testgear/siglent-sds1204x-e-released-for-domestic-markets-in-china/As yet we don't know which BW models will be offered, 100 or 200 MHz or both.What basic things it lacks against the SDS1102X is the 8" display and 50inputs but the SDS1*04X-E can do a lot more stuff.Wait a bit as Dave will have one to review soon.

content: Quote from: tautech on October 29, 2017, 11:02:44 pmThe Siglent Technologies SDS1102X is 460$ Canadian. pretty decent and in my price range. Ideally id like the 10" scope that Dave reviewed. BUT that's 2500$ Canadian.

content: If you're talking of the SDS2000X series, only the high end ones are that much and BTW they also have 8" display.There's a promo on them where you get the next BW model up at the list price plus a deal on the options.http://www.siglentamerica.com/pdxx.aspx?id=1488&T=2&tid=1But you have to buy the options, Decode, AWG, Digital etc and that's the other part of the promo:http://siglentamerica.com/qyxwxx.aspx?id=6388&sid=216Sus them out at Saelig online and ask for the EEVblog members discount in this thread:https://www.eevblog.com/forum/testgear/equipment-discounts-from-saelig/
