BTW: the GPP4323 can act as a DC load as well! --- End quote --- This will be very helpful and is potentially saving me from needing to purchase a separate active load. --- Quote from: nctnico on March 28, 2022, 09:23:49 am ---I ended up buying a Tektronix AFG31000 series (business purchase). It is a 'used' unit from a test equipment dealer but the one I got was like brand new in the box with several years of manufacturer warranty left. --- End quote --- The Tektronix are seemly becoming a more worthy investment to last over time if I can swing a few more funds into it. I'm gonna have to rethink the used test equipment dealers have as I've always thought most industries would have put the instruments through their paces. Have you also had good luck other purchases? ____________________________ --- Quote from: 2N3055 on March 28, 2022, 09:35:36 am ---Built in gen in SDS2000X+ has only one ch, smaller maximum output signal level etc. It is very basic AWG that is great in a pinch and mostly useful for Bode plot, because it's all in one... SDG2000X might be a good match for you. 2CH is useful any time you need to create two signals at the same time. AWG is a laboratory instrument that doesn't have predefined use. It's more of a universal building block you can use in many ways for your experiments. --- End quote --- I didn't know that the SDS was crippled in that feature! I'm seeing where a lot of differences are beginning to matter and stay budget oriented and get a device for each specific use case and then go in for higher end equipment when needed in professional setting where precision and accuracy is of a higher importance! Talking these nuances out are helping me see not to go over board on at this moment. |

But my best advice is to not buy equipment for what may be but for what you really need. You have a multimeter, PSU, get a scope (SDS2104X+ is a good choice) and then stop.. Put money on the side and wait for the need. And also, in USA, you can get all kinds of used PSU that might be used but still OK for very little money. Also other equipment. But you need to have few hundreds at a ready to jump in when opportunity presents.. Also, when in uni lab, pay attention what you use most on which projects... make note.. |

You might want to consider a used Metcal soldering station. There's plenty of them about, and their performance is going to be better than an FX888, even if it's a real one, which is by no means guaranteed. There are tons of fake FX888/951 out there, and they're getting harder to spot. |

At first I was concerned about buying Siglent products as they are made in China, but then I found out there was US (Ohio) tech support And a 3 year warranty. I spoke with a few of them and decided to go with Siglent. The SDM3055 is great, not sure I’ll need everything it can do however it’s there if I need it. A few weeks ago I ordered the SDG1032x, love it. Last year I was at an estate sale and pick up a Tektronix TDS3054B 500MHz DPO with all 4 probes and the battery for $250. It’s also has way more functions than I’ll probably ever need. The Siglent equipment doesn’t come with a complete manual, you can download them as well as the service manual (100+pages). I had them printed and then put them in 3 ring binders. I prefer paper, I can put notes in them. I looked at the DP832, 3 outputs is nice, is 3 amps really enough? |

Do you have some recommendations on the probes to use once *updated? I will need a little bit of time to brood over the level of DMM as I wont need that level of precision for a few years. --- End quote --- There was a promotion that included the logic probe kit, MSO license and AWG license for $1521 after 6% EEVBlog discount but before tax. Now the scope and logic probe kit together would be $1662 and the licenses are hackable so far. Hackability is what makes the SDS2104X a good deal, without that there would be a lot of licenses to buy. You don't need any new general-use probes, the originals work fine at 200MHz+. Beyond that with general-purpose high impedance probes is problematic and I'd not worry about it until you have a specific need. Where you're at, I wouldn't spend the money on a high-end DMM either. There's been endless discussion on this issue over the years and you have many options. Used equipment used to be a good way to go, but prices have gone up and good deals are much rarer these days. It wouldn't hurt to look around, but be wary. One DMM feature you won't get on low-to-mid end units is high input impedance--and once you figure out why that is important, you'll want it. |
