The best ones who make quality instruments... I always want one after seeing one in my college... I hope in future I will have one

[@joebarn2933]

I've been using oscilloscopes & ofcourse its dead now, but bloody hell. You make everything fun!! Wow Electric Engineering curriculum needs these videos!!

[@howardFL]

Great video, I actually learned the same information at work when I graduated, but this video explained everything in 12mins. Amazing, I wish you made this video earlier.

[@yaghiyahbrenner8902]

Hi great to hear and see you doing well. Love the new format, I remember being on the wrong path when I started building power supplies, just add more capacitors to maintain current! Then a new problem arises C=q/V, haha!

[@Impedancenetwork]

What a stupid comment.

[@Motorman2112]

Wouldn't the readback facility feed back into the programming? Is it typical for programming accuracy to be different from readback accuracy?

[@KeysightLabs]

From Bill: Programming accuracy really means setting accuracy. You can set the voltage from the front panel, LAN, or USB. Program accuracy defines how closely the voltage output will be to the setting. Readback accuracy defines how accurately we measure the output voltage which is displayed on the front panel, and sent over LAN, or USB.

Interesting video. Just enough information to whet the appetite but no so much as to bog down the viewer with either "homework" or get buried in facts and figures. Very cool. I came from the land of 'bushy eyebrow' wondering what could match Mehdi and I was not disappointed! Thank you for sharing! (Now, off to checking out the rest of the links!)

[@TheMechanicGamerVids]

These guys are over here going through all of these internal systems, I’m just glancing at my $30 variable psu

[@darkcognitive]

I need one of these to test amp draw from quadcopter motors, I think the load regulation feature would really help with that, as the voltage drops on lipos when i “punch” the motors. Can’t afford it though :/ .....maybe someday 🤷🏻‍♂️

[@sinx2200]

There are some fairly cheap versions of these, even then couldn’t you test the draw with a good multimeter? I’m not very knowledgeable though

[@tjipp42]

Nice done! You mention several important parameters, usually found in the datasheets for power supplies. One parameter that I think is harder to find is the supply’s “easy to use”. It is of course not easy to specify this and what is easy or convenient is also depending on your personal preferences. But I think there some universal features such as clear, logic and configurable display, possibility to set voltage and current both by keypad and knobs, dedicated output on/off buttons. How does Keysight work when designing UI? Can I as a user influence this? I have an E36313A and think it has really good UI, but really miss the possibility you had on e.g. the old HP66312A. With the left and right arrow keys you could move the cursor to one digit and when increase/decrease it with the up or down arrow or the knob. An easy way to step the output voltage in e.g. 0.1V steps while observing your DUT to see when it shuts down or wakes up. May we see a FW update with this feature? :)

[@KeysightLabs]

The best way to feed this info back is to call/email our support line and submit an enhancement request at www.keysight.com/find/contactus I've seen many features/design elements come to life that way. We have some R&D folks that specialize in UX, but it depends on the group.

[@ELECTROxigeno76.]

Hello good afternoon, I have a concern with my Sorensen LH 75-5 power supply, and I would like to know if you. You know if the behavior of this power source is normal, I bought it a few years ago but its use is not comfortable at all, I leave a link to my video on KZbin, here I present the fault, thank you very much engineer, .. Atte Ignacio, from Mexico ,.

[@Linguae_Music]

"Parametric Parameter" That was the cutest redundancy.

[@Linguae_Music]

It's like a circular circle :D

[@veryboringname.]

You could probably use one of your scopes to measure the output of your mic before recording to make sure it's high enough to keep the preamp noise down. ;)

[@AdiGitalEU]

Would be great to learn how to properly measure the parameters in home/amateur environment. Or even how to improve design.

[@Impedancenetwork]

What in the hell does this even mean?

[@keithking1985]

wow this is an awesome channel, i can't believe i only 1st seen it today.. (now give me a scope : ))

👍 More vids like this!

[@AKBRONCOSFAN007]

I am getting back into electronics as a hobby and my career. I'll be working as an instrumentation mechanic at a power plant. From the video it appears Keysight manufacturers triple benchtop power supplies, what models of power supplies do recommend for a novice like myself? I also just purchased "The Art of Electronics" and in Appendix L they recommend the HP E3630A but I've not been able to find any place that sells these units new out of the box. Any recommendations would be appreciated. I'm looking forward to viewing more of your videos. Cheers from North Pole, Alaska!🎅🎄

[@KeysightLabs]

North Pole, wow! The HP supplies aren't sold new anymore, but the latest triple output power supply is the E3631xA series. I use mine all the time. If you are more budget strapped there are some pretty good used options out there - they tend to last a long time.

[@snackentity5709]

thank mr keysight

[@finmueller7827]

I'm still using my analog power supply for stuff Also, hope you all feel well after catching it!

[@Anvilshock]

So the kids were running in terror from your 'stache you discarded but not from that painfully hipstery half-buzz-comb-over atrocity you kept? Oh well. Good to have you back!

[@ChrisSmith-tc4df]

He's still gunning for a walk-on role on The Expanse.

[@ChrisSmith-tc4df]

I wish that the E36313A had more annunciation options, such as 4 short warning beeps (similar to ST:TNG error) when transitioning from voltage to current mode that could be accompanied by fast channel button flashing on the affected channel. For an OCP trip perhaps there could be a long beep with the shutdown channel flashing slowly somehow. (breathing?)

[@samuelschwager]

Which power supplies support the Keysight bottle opener by default? ;)

[@KeysightLabs]

I think you could probably rig it up to the air vents pretty easily with a couple machine screws, the case is metal!

[@a1nelson]

Nicely done. Looking forward to more in the series. I’d be interested to see some non-obvious bench DMM details. So, basically the _opposite of this video. ;)

[@Macckos]

That is some nice stuff. I made LM317 regultator during my primary school times and since then was thinking about building something nice and compact for myself, but china products are stronger each year and my will to do that is inverse proportional :D

Thanks! A dedicated bench supply is pretty useful vs. a DIY option.

Glad to hear you are all recovering. I am a full time single dad with two daughters who unfortunately cannot work due to disability. I love the world of electronics and am teaching myself as a hobby and trying to teach my daughters too because it’s something we can all do together . I would be extremely grateful for any equipment you no longer need or use that could possibly be donated? I cannot justify spending money for an oscilloscope or power supply with my limited income. These items would be massively beneficial to my hobby and teaching for the girls. ( only very basic nothing too fancy would be required ) Thank you for taking the time to read my comment. Kindest Regards. Rich.
