2430$ for HMP4040 and what you get back is actually VERY good price. Holly shit. I wish I would knew about it, because it would literally replace 3 or 4 other power supplies I have.

Wago 215-311 4mm spring-clamp plugs are a good cure for PSUs with no binding posts

The color coding is of European style and standardized. The long posts are there to avoid an accidental contact with wires. The remaining question is, how fast the supplies are regulating and how much noise can be measured. The is especially important for automated testing. Since all of three them can be controlled by the LXI interface a it would be neat to control them via pyVISA instead of using Labview which is for casual usage too expensive.

whe you power up the NGE100 (time=13:10) the usb port moves inwards...sketchy

Blue because it's minus. Not common. Not ground. Minus. To emphasize it's galvanic isolation.

These license options… You paid 3000$ for a device, nice. It has all these nice features. It's in there, just pay us more.

They make great products, but I hope that the strategy to charge extra for connectivity features (about 200€ for the WiFi License Key) will change at some point.

"Verify Power Line setting and Fuse" :-) They know Dave...

The 1st signature on the cal certificate on the 1st power supply looks more like a scope trace than a signature?

Awesome supplies. Looking forward to the tear-down. Gut gespieltes Rohde & Schwarz.

The user interface is a bit confusing. We have one of the larger supplies that comes in for calibration, and it took a while to figure out the most efficient way to run through the calibration using the manual controls.

Wow! I now have an HMP4040 at work, a great power supply! Especially like the FUSE function, it turns off the entire group of channels at once if there are problems on one, it saved the boards more than once!

I feel a little underwhelmed by these supplies. On the 4040 they appear to have room for small print to show set points and if the device is in CC or CV mode. instead of doing that on the display they are using different colour on the buttons to indicate the mode. I don't like that idea. I think it would be too easy to get the wrong limit mode. I'm also not overly impressed by the fact that the supplies aren't capable of full voltage and current output on the channels. It doesn't seem to allow full ouptut on one channel and derate when you start drawing power from other channels The front panel of the NGE says 0-32V at up to 3A. If you look more closely at the front panel it says a maximum of 32 watts per channel. If you need 3A out you can only get it at about 11V. Still, good on R&S for supplying you the supplies. I'm sure they will find a use despite some of their design limits/choices.

"Imaging having a big stack of these on your bench, wouldn't you kill for that" ....literary puts up a stack of R&S PSUs seconds later :|

That was a seriously fun video! Very jealous! A side by side comparison between those beauties and the cheaper power supplies you can get would be nice. Showing how to use remote control would be helpful - what is needed to do it, how do you control the power supply and what would be some of the applications of it. Thx!

I'm sorry... But seeing some "software" add-ons on systems at this price (more than 500$) is totally unjustified... Every brands have done this in 20XX... But please what is the engineering cost of this ? It's just a world trade decision and no more... I guess that's the world we live now 😕

Wow Dave beautiful addition to the lab! Big smiles! :-)

Oh vey, Rohde&Schwarz.. If you read this, i'm lacking of lab power supplies too. If you don't mind.. ;) i could offer you 0 viewers

For Rohde&Schwarz, the different colors (white=Set/off, green=CV,red=CC) is quite usual. Sometimes on the display, sometimes on the channel keys or LEDS. Also the blue color for the negative output terminal is really common, cause it's a floating output. Black is more used for COM connection.

Blue stands for 'Not grounded Negative‘ Black can be misleading. With blue you be sure.

Wow, nice gift! $5,000 bucks US.

I'm sure they are well engineered and great built quality and all but honestly I feel like the user interfaces are lacking compared to offerings from AIM TTI (QL355, MX100). And even Siglent and Rigol seem to be able to make better use of the screen real estate. Also had a peek into the datasheet for the NGE's: ripple typ. < 1.5 mV (RMS) and < 20 mV (peak-to-peak) (meas.). Seems high-ish.

I love that HMP supplies. At work we use the HMP 2030 supply since it was released and last year we ordered the HMP4040. It's easy to use and performs quite well

The calibration of new equipment depends upon the user's industry and regulatory authorities involved. It is very common for Aviation rules to require local calibration of newly acquired equipment.

Wow! You got quite a nice present for my birthday! I just got a Blue ESR tester today, quite the piece of kit! Can't wait to fix some stuff around the house.

So far out of my budget it hurts a little, but amazingly capable instruments. I'd love the ENet interface, but it's amazing to see IEEE488/HPIB that I used to use. 4 Isolated channels can be extremely handy when working with analog circuits. Great video of well-designed, full-featured, professional gear.

Did you say " nob in ya face?' Lol!!

Nice! I was giving a thought and I'm going to make an effort and accept all of those low-quality PS to my very small lab... I know... I know... it would be hard but I'm willing to do it... take one for the team!

Wow, all outputs on the 4040 have sense lines. Very nice!

I could do with a decent power supply for my radio shack. I need to be able to supply enough voltage to charge an AGM backup battery, and I'd prefer something that isn't switched so it doesn't mess up HF reception. Any good recommendations?

And all I have is this lousy $3 buck converter and a battery pack.

Nice job R&S - lucky chap Dave. A tear down and review would be great.

NGE1xx is a low voltage power supply if you consider each channel separately, but you have 3 of them, so you can get to about 95V in series. Anything over 60V is considered high enough to require safety considerations. This would explain the shrouded posts and the missing metal plates, which I find quite a nice BTW.

Nice little bundle. I like the little one, the price is a bit higher than the Rigol's but still reasonable. Looking forward to a full review.

The blue terminals are in germany a thing, for laboratory stuff.

It is actually very common here in europe to have blue instead of black for the output color

HOLY SHIT!!!!! Big up to R&S for stepping up to the plate and doing what they did!! The new lab should be outfitted with top gear and props to them for stepping in and helping out. Great to see companies jumping in and doing things like that. So many people out here benefit from these videos and while this is nothing to sneeze at (those PSU's are NOT cheap!!!). Its great marketing for them but it's also making sure that great educational content is hitting the net by making sure the best gear is being used. Just my opinion though.

HMP2020 has software option for 3rd channel, just enter the key

7:00 some current there flapping in the breeze :)

3:02 I've seen that strange packing method before, on stuff from TagMaster AB from Sweden. I think it's done just to reduce waste compared to completely covering each end of the product in foam.

You're shitting me. They didn't send you the ones with all the options? It wouldn't have cost them any more to enable the Wi-Fi. Why do the 2020 & 4040 have those physical power switches rather than one like the smaller supply has?

Christmas came early very nice keep up the good work

Any idea how to control the 4040 from a PC. There is a visual basic download from their website but can't get it to work

dont turn it on! Take it apart!

Pomona sells the exact binding post/banana plus adapters you're speaking of.

Dave, your other "crap" power supplies are still way better than the ones I have 🤣😂

yeah i was catching on fairly fast that 5 amps at 32 volts is the max wattage and you would have to use 16 volts for 10 amps.

Repared a few HMP2020, they are build quite decent. Failure was due to user, shorted the reverse protection diode from the connector side

I have an HMC8043 and it's a really nice bench unit. I was considering an HMP2030 but it takes up much more space comparatively.

If anyone else also waited to see Dave stacking the HMP PSUs it happens at 26:00

You can parallel the channels, so the three-channel HMP2030 is actually just as good as the HMP2020, yet more flexible.

These were way to nice not to turn on before taking the screw driver to em RS did good on those pieces of equipment

Only single quadrant operation? No current sinking capability? I suppose not really a general purpose supply feature, but nice to have when you need it and something you get with HP/Agilent/Keysight 6631B/6632B/6633B/6634B/66332A supplies, for example.

With 9 PS channels, I will be sad if we don't get more physical demonstrations of electrical theory like the bypass cap vid.

At 13:11 when switching on the NGE100 the USB Port moves quite a lot. Hopefully this will not end up something breaking after a while due to stress movement on a wire or solder joint. At least this doesn't look trustworthy. Guess there ist room for improvement.

you'd think if they're sending these units out for review they'd go ahead and set them up fully-optioned. It costs them nothing extra and allows the reviewer to get a better impression of what the device is truly capable of. Maybe it's to not give the impression that the base configuration includes those options I guess.

How to setting ip address with NI?

'Hinged Package' ... It's just the way they manufacture it surely? Looks like they just cut the hole out and fold it over to make a pre-attached end? Would it help in transit? Or hinder?

Why I know I have issues? Because the crooked power button bugged me the whole time.

And i am over here using LM317 and LM337 for a 20v-0-20v 1 amp supply... Still trying to score a good supply on E bay or craigslist..

Do a video on the design of the binding post adapter.

any negative power supply for opamp testing??

I have heard about R&S and it is really good. I like their touchscreen oscilloscope.

In germany its quite common to use blue and red for low voltage DC stuff

I have had both an HMP2030 and an HMP4040 for several years. 2 channels of the HMP2030 are broken and BER. I replaced FETs and the controller in the switched pre-regulator which made them work for a month then they broke again. The HMP4040 is working fine, although the USB VCP serial port sometimes disappears until I reboot the PC. Driver problem probably. A nuisance since I often work remotely.

Can you please name that infinitely rotatable big round button? 16:55

I wish they would be offended at the ones in my son's set-up!

I got those Sahran N labels in my box too!

Their cheapest power supply is twice as expensive as my whole bench setup. Well, most of my stuff was either given to me or built myself, the most pricy thing being a $200 TV7 tube tester but still, this video puts a big small of my face. Please make a video about what's inside, I'm really curious about the big expensive HMP4040 linear power supply.

I like R&S gear and love my RTB2K and HMC8012, but when I needed a beefy power supply, I found that TTi offered a better value - my MX180T can combine 2 of the 3 outputs internally to deliver 15V/20A or 30V/12A. It is as good (IMHO) a professional quality build with all the features and controls that you would expect and still "only" about $1K. Now, if R&S insists in sending me a couple of these to check, I could change my mind.

used test equipment is the way to go. picked up a R&S spectrum analyzer originally specced at $120,000 for $800. seems to be that the more expensive they are, the less value they retain.

In germany Red/Blue is even more common than Red/Black (from my experience). Or it indicates isolated channels. Black for common ground, blue for negative potential (independent of other blue connectors).

Nice packaging... gotta protect your knob! :D

And here I am with my DPS5030... but to be honest, I’m happy with it. Although I’m guessing switching noise will not make it suitable for all applications. But I’m still new to electronics so I’m sure I’ll find out when I smoke something.

The popsicle power supply 🤣. I have some Hameg late 80’s early 90’s bench gear. Happy with it 😎

11:25 That's actually the NGE103B (not NGE103), which costs 890 EUR.

I always read the manual first. People not doing that are annoying.

Funfact: Mr. Rohde & Mr. Schwarz were both ham radio operators :-)

That's beautiful gear!

I’m so jealous, have a word with R&S please and tell them I need to replace my Korad supply with a decent one... I recken I could manage to cobble together a video or two.. Good on R&S for being so generous and sending you some cool power supplies.

I would love to see Keysight or another manufacturer now try to outdo Rohde & Shwarz. Next mailbag - everyone sends in their top of the line power supply.

Wow - free power supplies! I'm coming back as Dave Jones in my next lifetime.

Blue, because we here in Germany use blue wires for indicating a GND or Neutral.

as we always say here, dont turn it on TAKE IT APAHT

I conclude that the length of the binding posts is not only due to the need of the shrouded banana plugs. It is also due to the wire hole. Eons ago, I got curious about the possible benefit of black anodized heat sinks. I thought that would implement radiative dissipation. And indeed that does, but near room temperature rather feebly. The radiation is dependent on absolute temperature of heat sink (kelvins) to 4th power minus opposing surface absolute temperature to 4th power. When both items are not radically different, or both are nearly ambient temperature, even the 4th powers are not so different. You start seeing effect when heat sink gets near 100 degrees C and the radiation counterpart is a wall at 25 degrees. But here comes another issue. The heat sink typically is ribbed. That means the effective radiating surface area has been folded down to maybe 1/10. So, convective dissipation even without a fan stays effective, while radiative power was cut down. Free convection is proportional to about temperature difference raised to power 1.25. Fan assisted convection is many times more. After that exercise, I have never worried about the heat sinks not being black any more.

5:14 What?! No GPIB port? I am shocked!

I'm not sure I've ever heard Dave as giddy about something new as here: 3:38

By the time you have bought the high resolution plug in for the dp832 you are not far away from the nge103.....though the specs are quite a step up!!

The top vents are for let the smoke out

Iwill pay shipping for any of your trash, lol!

THese are clearly from their Hameg acquisition. Hameg uses those cases and they are standard depth

These devices are so different from one another I suspect they are from different oem manufacturers and not (all) directly from R&S.

I still prefer the interface of my dp832, although the specs are nice.

It's really not a 10A capable supply through the whole range (HMP2020). It's limited to 160W. At max V it's less than 5A.

Binding posts on the little one have a silly look

So Dave, now that you have such a nice set of new power supplies, you probably won't need your old ones any more. I'll gladly pay your costs if you care to sell one to a struggling retired tech in need... :)

I've only got a 0-18V 0-1A supply I just built myself.. I even wound my own transformer! Still not as fancy as these babies though!

In Germany it is normal to see negative in Blue

I reckon Shango066 would be pleased with your late Xmas presents.😉🙋

$5K US of free power supplies..... NOOOOOOIIIIIICCCCCCCEEEEEE! Good stuff! Makes my old HP supplies look like toys!
