Good quality but some features are Pay-To-Play
4.0
I like the scope, its usability and quality, but some of the features that are specified are paid upgrades and I would have purchased a cheaper model if I knew that. Fortunately, Rigol was running a promo that gave away all of features that I wanted for free. Make sure you check out Rigols website.

Rigol MSO5104
4.0
Haven't had the chance to utilize the equipment other than power on, test button operation. Did connect to an HDMI monitor. Didn't see anything in the specs about what the HD resolution actually was. It's not 1080p/i. A bit lower. On a 24" display, the image is a bit "cartoonish" in some way, not really sharp as I'd hoped. Never the less so far am happy with the scope. Service from tequipment is top notch and would highly recommend their services. They provided probes for each channel. I included the logic analyzer cable as well, looks nice and complet connectivity wise.
Only left a 4 rating due to the HDMI output resolution.

For the money
4.0
OK boys and Girls, this is not a $1000 meter. If you are in the market for a lower end meter this unit is very acceptable. There are some things that really bother me like the continuity tone is so low I can barely hear it. It does not seem to be adjustable, after a bit I will crack the case and see what can be done.

lives up to it's description
4.0
Powering up I didn't have any problems. Checking outputs further I found the touch screen easy to use. I did find on arbitrary functions that rising and falling exponentials are the opposite of how they are shown on the touchscreen. Mentioned this to Rigol and didn't hear back. In general the functions go to their limits viewing on a scope and are pretty good. Some ringing on the square wave, but that's pretty standard depending on the test leads used. The generator's amplitude output didn't match my scope's measure using peak to peak but a fairly close match using amplitude. I'll have to think about that when I want to make measurements to 2 decimal places. I didn't know beforehand many of the math functions in the library. I found quite a few are similar in shape, so not as much variations in inputs as I had expected. Also my unit was calibrated 1and 1/2 years earlier. I didn't think much of that.
But the unit does have nice outputs and ease of use, particularily once one uses it a bit. I consider it high tech and better than other generators I have. I do feel the extensive library of arbitrary functions is a nice bonus, despite what I mentioned earlier.

Very capable but one small problem
4.0
It does everything I wanted but it has one small problem. After loading an arbitrary waveform from my computer I cannot save it local to the DG822 or an external flashdrive. So, every time I turn off the DG822 I need to re-load from my computer. It will save states of "ordinary" wave forms but not arbitrary ones.Rigol applications support has been very helpful but they could not offer a solution to this problem.

Handy and great value
4.0
This little function generator has lots of features in a small easy to use package. Will I use arbitrary waveforms or modulated waveforms? not right now, but I didn't see the need for a dual tone generator until a DTMF project hit my to do list. It was great to have that capability without having to build a dedicated DTMF generator (just to test the decoder).
The generator is easy to use and fairly intuitive. The touch screen works well. The rotary control is useful to quickly change values without having to enter them directly from the pop up menu. Entering numbers directly from the pop up is not difficult and I never had an issue with "fat fingers" causing an entry error.
I found the 10 user presets to be very useful although I was disappointed to find a software bug with recall. It does not appear that it correctly recalls the DC offset so for example if you have a waveform you saved as unipolar, it is recalled as a bipolar waveform and you have to go into the menu to restore the correct setting (by selecting and then deselecting offset adjust). That is bad enough but it is more annoying that the user interface shows that it DID correctly recall the offset even though that was not applied ( a silent failure).
I agree with the criticism about the number of digits displayed for each parameter. I had to disable the comma separator an replace it with a space to make it more readable. For most uses it is redundant to have a string of 6 zeros trailing the value that you actually set.
Despite these shortcomings if you are looking for a basic function generator it is a great choice. It does a great job of basic functions and has much more capability on top of that.

Great Addition the Lab Bench
4.0
This unit has replaced a different lab supply that had issues with changing/losing voltage settings which was very unnerving. The DP832 has great options for setting and saving configurations and so far it was worked very consistently. It takes a bit of effort to navigate those functions but there is a lot of flexibility.
Physically the unit is quite long but workable. The fan noise is louder than I would like but not whiny like other test equipment that I have so it's not as annoying. Would get 5 stars if the fan was quieter.
Very happy with this item.

Rigol DG822 Function Generator
4.0
I have not had this unit long enough to give it a far review. As a result I am only giving the DG822 a 4 star rating. So far what I have checked has met or exceeded specs. I like its features and the fact that it can be upgraded through software. Because it does not have a fan it is very quiet. It is good looking and the specs are great for the price of this generator. Once I have more experiance with the unit I have no reason to believe it will meet a 5 star rating.

MSO 5104
4.0
This is a good looking scope. I bought the 4ch 100Mhz. The screen is big and clear. I connected two 100Mhz sine waves to Ch1 and Ch2. I used the cursors to measure phase angle differences. I did some Channel A - B math. I lowered the sample rate and set the averaging button. The menu structure seems to make sense. Things are where I expect them to be. The screen is a touch screen. I thought I wouldn't use that much but within 20 minutes I was moving waveforms around, setting trigger level and moving measurement cursors by touching the screen. Touching the screen was more natural than I thought it would be. I always used the soft buttons around the screen and though I would never like using the screen to select items or adjust the waveform but I eventually came around.
Rigol makes good stuff for the price which means it has good value. I gave 4 stars because there is always room for improvement. I'm happy with what I got and will probably buy Rigol again.

Excelent Power supply with built in turbine
4.0
I got this power supply over a year ago and it is a solid performer on my workbench. It's used for hobby applications and I never had issues with it. I mainly use it from the front panel but tested some simple setups in LabVIEW in combination with the DM3068 DMM and a DS2302A scope...no issues.
It took a little while to get used to it but now I really like the user interface.
The huge complaint is the build in fighter jet turbine. I thought the DS2302A scope is loud, after I installed this power supply I learned the scope is whisper silent. I don't know how you can design bench equipment that is designed to sit in front of the user which is so noisy. Yes it's not a pricy power supply but the efforts to minimize the noise aren't too pricy either.
My unit is out of warranty now and I will definitely look into alternative fans that reduce the nose without loosing air flow.
Other than the noise complaint this is a very nice power supply for the price.

Solid Power Suppply
4.0
This is a very solid and nice PS. I was a bit surprised how heavy and large it actually is. There is one complain which is the loud fan. There are some mods out there to replace the fan with a quiet one but it's not as straight forward as you might think since you have to make sure to match the current of the original fan and of cause you will void the warranty. So, please Rigol spend $8 for a quiet fan - well the fan of my Rigol DS1052 is even louder ;-). Anyway, I highly recommend to watch the EEVblog reviews on the PS as it gives you a lot of great info.

The power supply is nice, but the output is a little off. My channel 1 shows a 9mV difference when measured with a multimeter. Also, the output does not go to zero when i shut the output off. Instead, it goes to some mV value (from 5 to 9). Other than that, it is a fine power supply.

Excellent Power Supply
4.0
The Rigol DP832 has been working great for me. It is very intuitive and easy to operate, and the quality of the DC output is superb. I really enjoy the ability to turn each channel on and off individually.
The reason I removed 1 star is because:
1) The High Resolution Display/Control should be a standard feature, instead of an extra $110 for the unlock code. Everyone can benefit from the fine resolution control. I am OK with the other locked features being extra cost, since not everyone can use them.
2) I wish there was a way to internally configure the power supply to put channels 1 and 2 in series. They can be manually connected with a short jumper wire, but cheaper power supplies have this feature...and I am naturally lazy enough to not want to walk across the lab to get a jumper cable.
Overall, a great power supply for a decent price.

Quality DMM
4.0
The accuracy and responsiveness of the DMM is very good, as other have mentioned. I like the fact that I can control the characteristics of the display (brightness, contrast & invert).
There are two issues regarding the probes, I feel should be addressed.
The sheaths on the probes can be difficult to remove. At first I thought they weren't removable, which didn't make sense considering that they came with threaded alligator clips. I contacted Rigol in Beaverton OR and they informed me that the sheaths can be obstinate to remove initially and to use a set of needle nose pliers to remove them. That worked like a charm and now they come off with reasonable effort.
The second issue, also deals with the probes. This may be an isolated issue, however I thought it was worth mentioning. The probes I received, although they are well made, do not provide consistent readings. I swapped them with a set of Probe Master probes and the issue went away. I also tried the Rigol probes on another multimeter and had the same issue. Maybe it's just my set.

Nice power supply
4.0
I'm very happy with the supply. Having a good linear supply on my bench is important as it doesn't have all the high frequency noise a cheap switcher has. I looked at several reviews including the one on eevblog and have found it works well and meets my expectations. It took a bit to get used to the user interface however in now find it easy to use. I recently used it to charge the lipo batteries in a piece of gear, being able to current limit was important and it worked very well. I plan to buy the hires display option, the only reason I gave it 4 stars is it doesn't come with the option from Rigol.

This model makes a great bench meter. You don't have to constantly set up the number of power cycles, triggering delay, resolution, etc like the 6-1/2 digit meters require. The 3058 has greater accuracy than most hand-helds, no fan noise, good display and lots of features. And, all the documentation for the meter is right here on the web site, so you can see what you are getting.

DP832 triple output power supply
4.0
This is a precision triple output power supply. It has 2 independent 0-30 volt outputs and one 0-5 volt output.. The middle 0-30 volt supply is not isolated from the 5 volt supply. This will probably never cause a problem in my case.
I like the corner bumpers which allow me to stand the power supply on end instead of setting it on a table if the situation merits it. This unit is upgradable to one extra digit if it is useful to you. The upgrade should be less than $100.00 US$. Too many features to mention. The only thing so far that Rigol could improve on this is to make the adjustment control knob stick out more so that you are not wheeling it around with your finger. Other than that the supply seems to be a very good buy for the price!

I have put the Rigol DP832 through a series of test/evaluations and find it good in all respects. It is easy to use, quite accurate and should suit almost everyone's needs.
The software is not top-level, but is useful; I had to export data to a csv file, which opens in Excel, to determine the energy (power x time) used by an LED array that I evaluated.
One minor nit is the additional cost for more accuracy and other features; but this seems to be the way of much current technology.

Rigol DP832
4.0
I am quite pleased with the power supply and as I am just a hobbyist it was a big purchase for me. None the less as value per dollar I consider it rather inexpensive.
First the bad parts, the jacks are a little tight and all my leads don't fit in as well as they should. Once the warranty is off I will probably drill or sand them out. I find this quite annoying and feel it drags down the unit considerably when judging quality of build. The other thing I find quite annoying for me is the length of the unit. It is considerably longer than any other piece of equipment I have so it does not sit well on my bench. That being said I knew the length before I bought it and still went ahead. Two minor issues are the fan noise and it has a color screen, why not let a user use it as such.
Now the nice parts. I thought I would hate the keypad layout, turns out I love it. The unit is responsive and switches nicely as the power is brought up and down. It switches from output to output nicely and the display shows this clearly. Although I faulted the lack of nice color display patters the display is beautiful, it is crisp and easy to read even from across my bench.
To summarize, if I were to be able to choose this unit over again, I would. Hopefully my jumper leads will fit properly in a newer production model.

Tremendous Value
4.0
This bench power supply is incredible value at a $450 price point. It has all the features I was looking for plus options for upgrades. I also purchased the Hi-Res option for 1mv/ma resolution.
I agree with most people that the display is much better than on the DP832A. I don’t know what Rigol was thinking. It would have been nice to have a slightly larger display for my aging eyes, but it is definitely adequate.
I would have given it 5 stars if it were not for the issue of the output terminals. The banana plugs are inconsistent in sizes. I had to ream the holes out so they were all the same. Not that big a deal. For some it might be.
All in all, very happy with this unit.

Great power supply for the money
4.0
I have been using this power supply for a few weeks now and I so far I like it. The interface might seem a bit weird at first with the ring of number buttons, but it works pretty well once you've gotten used to it. Based on the limited test gear that I have, it appears to be well within its claimed specifications. I've been able to leave it for long periods of time (2 hrs) outputting ~60 watts out of two channels without issue.
The only issue I have with this power supply is the calibration date. I understand that there will be some time lost due to shipping and time in a warehouse, but the unit I received will require calibration only 2 months after receiving it. I don't care that much about the calibration because I'm using this for my electronics hobby, but I'm sure some people will.

Received the DM3058E last week and have been very happy with it's performance so far. Until now I have used a radio shack handheld meter and a bk precision. So this is my first bench meter. It's responses is very fast and adjustable which is nice. One item I did not like is the low volume buzzer it has which is hard to hear. In a continuity test I found it much faster than my handheld meters but not as fast in detecting continuity as say a fluke 27 but not bad at all. I am very happy with this meter and it has features I have as of yet to use.

Allot of meter for the money

The unit itself rocks. I have had no issues using it on a daily basis for over 2 months. The feature meet my needs and the unit is relatively accurate for the price point. It is intuitive and easy to navigate. the unit powers up and is ready very quickly.
Only 2 complaints.
You have to reset the display mode every time you power the unit. For example, if you set the display to invert (Dark background, light colored text) you have to reset it after every power cycle. it is somewhat annoying. After a little while it just becomes routine during the start of your day.
There was not allot of probe swag... Just the probes and alligator clip attachments. The probes/leads could have been a little longer.
Outside of the above, it was a good buy for 5.5 digit meter.

Easy to use general supply
4.0
In general I'm very happy with the operation of this supply. All features I've tested work as expected. Rating marked down due to cons.
Pros:
* I've found the somewhat odd but flexible value input control very useful for fine and coarse control.
* High accuracy option usually eliminates need to add external voltage and current meters; displayed values were within specs.
* Channel controls are easy to use. Ability to turn channels off and on is very useful.
* Over-voltage and over-current controls work well, and can prevent damaging circuits.
* Remembers last values entered between power cycling.
Cons:
* Entering feature option codes is unpleasant, difficult and slow. In some cases they won't work if microcode isn't correct but it isn't obvious that's the cause.
* Not all outputs are independent; grounds are shared between 2nd 30v and 5v.
* Takes several seconds from time power switch is turned on to when the supply is ready to use.

Great budget bench meter
4.0
This meter has plenty of features for hobbyists and low-level industrial/commercial work. As long as you don't need ethernet capability or the other communication protocols of its bigger brother, it is just as useful as the DM3058.
Two things kept this meter from getting 5 stars. The first is the small internal datalogging memory of only 2000 data points. The other is the annoying soft power button on the front panel of the meter. There is a hard power switch on the rear, but the front button glows in a pulse pattern like an Apple product. Completely out of place on a piece of electronic test equipment.
