content: I am using my newly-arrived SDG2024 AWG in a useful fashion! Along side is a Tek TDS2022B. Now, I am wondering if I should put the Tek aside and get one of the new SDS2000X-E series scopes. The ability for the scope and AWG to talk is pretty cool.My Tek is fine though dated. It outputs to a usb stick at a snail's pace and the output is so last century.I don't do any really high-frequency stuff, so the 200MHz is prolly fast enough...that is what I have now.Thoughts?

content: Here's a look at the 350 MHz model:https://youtu.be/7zJ8X51l0GoMy thoughts, if 2 channels are enough have a look at the SDS1202X-E as it's just a little more than 1/2 the price of a SDS2022X-E.They are almost identical to use excepting the 2kX-E uses a shared vertical control and has a few additional features adopted from the more recent SDS1000X-E 4ch models.The 2 GSa/s, 28 Mpts memory and the later features added (webserver, Bode plot etc) add up to a few $ that you could use for something else.However maybe the 4ch SDS1204X-E could get you these later features for a little more $ over the SDS2022X-E.Then all you're missing is the 2 GSa/s as the total memory still is 28 Mpts as each ADC in the 4ch version has 14 Mpt support.Anyways, if the Bode plot is something you'll use go with either a 4ch X-E or the later 2kX-E as your SDG2042X will interface directly with either to provide the swept Sine wave for Bode plots.Sadly Bode plot capability is not available for SDS1202X-E unless you do it 'old school' like Dave in an old vid:https://youtu.be/uMH2hGvqhlEI'll leave you to do some head scratching.

content: Well, the whole motivation was inspired by the AWG and the ability to do things like BODE plots. Classic case of more money than brains, I guess.If I am gonna discard the Tek, I gotta get something for it...I mean...the Tek has been good to me

content: I have a TDS2012B (busted), a good DSO but either of the X-E Siglents offer more capability with deeper memory depth, better FFT, fuller trigger suite, Decode and more connectivity options. Any of the X-E's would be a significant upgrade to your Tek and the SDS2022X-E the best choice if you're happy to stick with 2 channels as they're just $ 620.What's a 2nd hand 200 MHz TDS2022B worth in the US ?Probably wouldn't cost a lot to upgrade.

content: Quote from: tautech on March 24, 2019, 12:03:23 amLOL...an honest broker!! Could you post an image that you get from this or equiv. scope, when you save a trace to USB stick? That is my other beef with the Tek. The images are pretty crappy.

content: Quote from: Wimberleytech on March 24, 2019, 12:28:22 amNo, you only need the FG licence when using the SAG1021 (external HW optionhttps://www.siglentamerica.com/accessory/sag1021/) when using it for AWG capability when controlled by the scope.Zero additional licensing is needed for Bode plot usage when the scope's tethered to the SAG1021 or any Siglent AWG.Quote from: Wimberleytech on March 24, 2019, 12:23:44 amSure, but a little later as I'd have to get one out so get some sleep and there'll be something here for you tomorrow.X-E's can Save in a # of file formats but the simplest and best is the blue 'Print" button on the front panel where you get a few 10's of KB PNG image saved to USB. Takes a couple of seconds to process the screenshot and dump it to USB.Saved image quality depends if the scope is free running (repetitive waveform) where subsequent acquisitions are overlaid on the display to then be saved or if the scope is Stop'ped by the user or trigger event (Single, Normal or another trigger setting) where then only a single display acquisition there to save.Naturally a better sampling rate and more memory will provide more sample points for any given timebase setting and hence a more defined waveform reconstruction.Edit to add.Likewise ^ with the DSO Stop'ped at some slow timebase and then the timebase magnified somewhat to where you may have many less acquisitions on the display where you effectively have much less real data displayed and therefore a finer trace.

content: Quote from: tautech on March 24, 2019, 08:19:44 amI think the inverted background renderings from the SDS1104X-E, and possibly other Siglent scopes, would be much improved if the colors were adjusted for better rendering on a white background.The yellow text on white background (or gray, for that matter), is pretty hard to make out, at least for my eyes. Same for cyan text.If I were to offer a suggestion to Siglent R&D, it would be to adjust the color palette used for the output file, so that the hues are made a bit richer. So render yellow closer to orange, cyan closer to royal blue, and so on. This is the approach used by some other scope manufacturers, and it improves legibility a lot, IMHO.Just my 2 cents' worth.

content: Can anyone confirm that the Siglent scopes (SDS1104X-E) also works with older awg's like the SDG805 or is it only the newer X series SDG's ?

content: I think it should work. Just wanted to be sure.The firmware revision history says:"2018/02/27 6.1.20R1 1. Added Bode Plot support for all of Siglent ’ s SDGinstruments"Also this page states: "In this note, we are using a 500MHz SDG6052X, but any SDG series (800/1000 series, 1X, 2X, 6X) can communicate via USB cable to an SDS1004X-E"https://www.siglentamerica.com/application-note/bode-plot-filter-oscilloscope-generator/But this page/video says it only applies to the X series SDG's:https://www.siglentamerica.com/video/bode-plot-oscilloscope-generator/Guess he just means the dual ch setup in the video.
