content: So I bought everything I need to keep me busy for a very long time. I am taking EE in college so all of this gear is going to help me out with that. The last few semesters I found myself not being able to finish my experiments in class. It was usually because I got caught up helping others with their calculations etc. Anyways, here's what I bought:Oscilloscope:Rigol DS2202A - $1342.00With this purchase I got a free option upgrade that includes:AT-DS2 - Advanced triggeringCAN-DS2000A - CAN Triggering DecodingMEM-DS2 - Memory upgrade from 14 to 56 million memory points in a single capture.SD-DS2 - Serial data decoder. Includes RS-232, I2C and SPIhttp://www.tequipment.net/Rigol/DS2202A/Digital-Oscilloscopes/This oscilloscope is so much better than what I was using in school! This thing is beautiful.Digital Multimeter:Rigol DM3058E - $469http://www.tequipment.net/RigolDM3058E.htmlI got a bench meter because I wanted a bench meter. It's there, it's never moved and always ready to go. I do need to get a handheld DMM though. This way I can have one set up to take one type of measurement with the other to take another. I still haven't received this item yet. The place I bought it said it would be shipped on the 24th. I checked my account online it says it still wasn't shipped:/ Hmm.Power Supply:Rigol DP832 - $450http://www.tequipment.net/RigolDP832.htmlI bought two of these because my professor had us doing experiments that required 4 voltage sources. These are the updated units. i can see the larger heatsink through the side of each unit. I want to check for that current bug and the voltage spike when you turn the unit on.Function Generator:OWON AG2052F - $375http://www.saelig.com/owon-ag-series/ag2052f.htmI bought this because I use function generator in school and want to work with signals. It's a nice unit.Solder Iron:Hakko FX888D-23BY - $96.72Hakko FX888D-23BYBread Board:Global Specialties PB-105T - $87.55http://www.tequipment.net/Global-Specialties/PB-105T/Breadboards/Miscellaneous:I bought a bunch of small stuff as well. Connections, RG-58 wire, Pomona 18awg silcone wire, bread board wires, electronic components, BNC crimper, pincers, and so on. Bought most of this stuff on Amazon.

Some of the cheaper Chinese test leads are very poor quality - i.e. small gauge wire and not soldered on the ends (like alligator clip leads). I just make many of mine because I know if I make them they are of good quality construction. Many of the common connectors such as banana and alligator clips are available. As far as BNC, I use crimp-on connectors exclusively.

content: Quote from: cvriv on June 20, 2016, 01:05:31 amA forum search for that PSU doesn't produce any results while "GW Instek PSU" give 9 pages, might be worth some study?IMO the most important consideration for leadouts is a "nice" wire, it's not often you want to put lots of current down them but they need to be nice to handle and "behaved", not stiff and coily.For nice one I got this silicone sheathed stuff from RS. # 267-983. It's not heavy but lovely to handle.

content: Quote from: cvriv on June 20, 2016, 12:19:16 amI'd go with:Rigol DS1054Z for a scope (riglol it)Rigol DP832 for a PSU (riglol it)Siglent SDG2042X for 2ch AWG (e.g.http://www.saelig.com/siglent-waveform-generators/sdg2042x.htm- they also offer an eevblog discount), can be hacked but probably not worthwhileDMM - PartsConnexion has been selling off an inventory of used Keithley 2015's.http://www.partsconnexion.com/test_analz.htmlBut you also find them one eBay (Such ashttp://www.ebay.com/itm/KEITHLEY-2015-6-1-2-Digit-THD-Audio-MultiMeter-fully-tested-w-warranty-/371553124387?hash=item56824ac023:g:a4oAAOSwWTRWvjsh). A well-working K2015 for $350 (if you don't need the flanges and handle) is a nice starter IMO.Get a quality set of probes (see probemaster.com), some random 50ohm RG58 BNC cables and adapters/T's/terminators, a decent breadboard, some Pomona 4mm banana cables, 28awg solid copper wire, a Stripax stripper, a pair of small side cutters, and go to town!Should fit within the same budget, maybe even save you a bit.

content: Didn't the DP832 have problems? I saw the eevblog video for it. Didnt it have heat problems and something else? Its a nice looking psu but i thought it had problems. This is why I didnt consider it. Im trying to keep the psu around $400. Any other suggestions or reasons why i should get the DP832. I need two of them as well. My professor had us doing projects that needed 4 voltage inputs.

content: What are you planning on working on, and do you really need such a fancy function generator? I would much rather put that towards a better scope, or more parts, etc. There are plenty of used generators for very little money on eBay. They may not have fancy UIs, but do you need this? Maybe you do. Do you really even need more than a few MHz? Perhaps you do, again, depends on what you want to work on. But pre-buying equipment you won't need or use for a year is a waste because it will be cheaper and better next year.Remember you can anything you want. You just can't have everything you want. So I like to think to myself, "What else could I be spending this money on?"

As with other electronics, cars, etc., it's best to avoid the first version of a product. They don't call it "bleeding edge" for nothing.

content: Quote from: FlyingHacker on June 20, 2016, 04:09:20 amAll good points. I'd say the same principles apply to the other equipment as well. Although they look really cool and all, what do you really need from each of them?It's also worth checking Craigslist or asking around if any recent graduates as well as people switching majors are selling off their gear.Of course, if you've got a whopper of a budget, then maybe none of this matters. Then again, if that was the case, tautech's cheeky comment would instead be legitimate.

content: Personally, I went with used equipment, even though I am in my early forties and have a real job with excellent income. However, my job is not electronics.I would get high end equipment that was old or needed repair. Like buying a used Mercedes vs. a new Hyundai. One is quality that will last for many years. The other will get you from point A to point B for not much money, but won't last terribly long (I don't want to start a car flame war, but I think you get the point of the analogy.)I have learned a lot repairing equipment. Older test equipment often has really detailed service manuals. They go over the theory of operation, the schematics, trouble shooting etc. You learn a ton form these documents.

When you set the channel to less 10mA.As far as the oscilloscope goes... I chose this one because awhile ago i posted a thread here and was told to get that one. The ones I wanted to get were so much more. Now that ive settled, you guys are telling me to get better.

content: 1. Not sure you need a 200mhz scope. The basic model can be hacked/unlocked to save you some coin.2. Do you really need a 5.5 digit bench meter? I think most people would suggest getting 2 hand helds, so you can measure voltage and current. Bench meters are good for no batteries and logging.3. Hakko soldering iron is good.4. Function generators, do you need an ARB one? $800 seems like too much for a beginner. Maybe start with the feeltech.Also consider the siglentsSiglent SDG810 10MHz = $282.Siglent SDG2042X 40MHz = $499 (can be unlocked i believe).4. The 832 should be safe enough now. Lots of people here have one. Lots of bargains to be had with used power supplies on ebay. hp/agilent/keysight, power designs, etc.

All that extra CPU headroom for all the hacking fun. It really depends on what you want from a scope and what you want to do with it.People would suggest getting both a digit bench meter and a handheld multimeter.

Ill soon find, or maybe I won't find out.About the oscilloscope, i had originally said I was going to get a basic scope for 399 amd some said get a better scope. I had intentions of hacking it as well. Now i have an even better scope that I wont wont make full use of for awhile. Who cares. I just want to get started experimenting and reading through my books again before next semester.Im very glad I have my gear now so i can do all of my school projects at home. The whole point is so that i can start spendind more time with my hands messing around with the gear and components. I did 2 semesters already and spent most of the time doing calculations. Id lioe to continue with the calculations but spent more time try to understand how the components work by messing with them.

content: You will want at least 4 meters. Seriously, I find myself hooking up lots of meters all the time. More info is better to have. It makes it much easier to see what is working right and wrong.I have a few handhelds (Fluke 87V, Fluke 27, Triplett 60 (favorite analog), Triplett 631, Simpson 260, an old RadioShack meter I bought in college (25years ago)) but I tend to use the bench meters (I have 5) the most because they are always setup and ready to go. The require no batteries, and have Nixie (https://www.eevblog.com/forum/repair/nixie-tube-fluke-8100b-dmm/msg768407/#msg768407), VFD, LED or otherwise illuminated displays. You can get nice 4.5 Flukes for less than $50 on eBay. I got a 6.5 digit Keithley for less than my 87V. You really don't need insane accuracy for most of your meters. Just one or two really good ones.It can be very useful to have an analog meter or two. This makes it very easy to see trends, to peak circuits, etc. I would suggest a Triplett 60 (I have type2) as it is extremely rugged and crazy accurate for an analog meter.I am a big fan of VTVMs as well. They are usually at least 11Meg input impedance (I have one that is 26Megs). They are quite cheap on eBay, and easy to work on.So a long post to say be sure you have a number of meters, even if some of them are the Harbor Freight trash meter, which can easily be used to measure voltage in small circuits.

If you plan on sticking it on mains that is when it is nice to have a well built meter.Fluke 27fm is pretty cheap on eBay, and a good mains meter. Dave has a video on one.

If, for example, you need to measure very small changes in voltage or current, most handheld DMMs will not suffice because they lack the resolution.Collecting together your requirements with as much specificity as possible will yield the best advice when asking on the forum.
