    Ni is always just like these. I happen to be a bing fan of NI 20 year back. But it turns out Ni just makes fancy designed instruments whics are rediculously over-priced! That is why it keeps losing fans and finally sold to another company!

    Made in Malaysia – no wonder it's so expensive!

    Real funky, ugly, looking instrument. Integration of tools was limited in my day. The only integrated instrument I had was a Sencore video analyzer, comprised of a supply or two, color bar generator, signal generator, I think.

    The Tektronix modular TM 500 and 5000 series gave a good variety of tools within a single frame although somewhat limited and very expensive.

  4. Avataaar/Circle Created with python_avatars Nanocosm says:

    Is another reason to use an LDO in a bench supply that has a switching pre regulator to have a small output capacitance?

    You have a big cap on parallel with the load on a standard switcher.

  5. Avataaar/Circle Created with python_avatars Wesley Hayes says:

    Price point seems high till you consider how it will integrate easily with ni software such as labview or test stand.

    Can imagine it'd be great for school

  6. Avataaar/Circle Created with python_avatars Ultra-Violet-Light Crayon says:

    That's typical of U.S. products. Worth every penny.

  7. Avataaar/Circle Created with python_avatars Sebastian Zorg says:

    Love You video cause my girlfriend (ahah) hates You. Ahah)

  8. Avataaar/Circle Created with python_avatars MVVblog says:

    For $5,5K this is a non-sense device.

  9. Avataaar/Circle Created with python_avatars Bodragon says:

    Did they let you keep that thing?

  10. Avataaar/Circle Created with python_avatars Wi_Zeus says:

    Can someone please explain how the +/- 25V is giving out 50W of power? Is it effectively 50V at 1A, when measured across the output?

  11. Avataaar/Circle Created with python_avatars wolfgang Beginners-Mind says:

    It dose have a FFT check out the data sheet, and they go up to 500 Meg

  12. Avataaar/Circle Created with python_avatars Vaughn Rhinehart says:

    Surprised to see this kind of high caliber design in an educational product. I assume this is made for beginners in electronics because advanced students would likely be supplied separate instruments for each of these purposes.

  13. Avataaar/Circle Created with python_avatars Crocellian says:

    A little worried how weak the software is. Way too much hardware. Looks like the software is just a GUI.

  14. Avataaar/Circle Created with python_avatars linuxmintman says:

    if you could you please take a look at the NI DAQ? It comes in an educational format with a FPGA.

  15. Avataaar/Circle Created with python_avatars John M says:

    Nice Breakdown!

  16. Avataaar/Circle Created with python_avatars Toomas Rett says:

    Hello.
    I have used NI USB-6251 DAQ in the past. My speculation for the extra FPGA processor is to run locally, instead of of of your computers slow USB connection. Allowing all processes to take place simultaneously without any real-time lag between control and read-back of data. I like this tear-down…

    Thanks,
    Tom

  17. Avataaar/Circle Created with python_avatars Jabba Catski says:

    A snip at £ 4,560 plus 20% vat on top, I'll take half a dozen…

  18. Avataaar/Circle Created with python_avatars Dave McAnulty says:

    6K!? You could get REAL gear with that! Wait…could you? Off to Amazon with 6k budget

    $4520.00 Rigol DS4034 4chan 350MHz Digital Oscilloscope (inc free 500mhz upgrade)
    $379.99 Rigol DG1022 20 mhz Arbitrary Waveform Function Generator
    $386.99 Fluke 87-V Digital Multimeter
    $197.90 B&K Precision 1670A Triple Output Digital Display DC Power Supply, 30V, 3A
    $599.00 Saleae Logic pro 16 (not on amazon)

    $6083.88 (that took a lot of tweaking to get that close to 6k let me tell you!)

    Now I won't argue that the real gear is better for EVERYONE. Maybe you have no space, or need to keep things SUPER portable. But for most people i'd think the real stuff would be better, plus you'll be able to use all this stuff for years and years after you leave school. And when you do leave school, the tools you use at your job will resemble these ones more than the virtualbench ever could.

  19. Avataaar/Circle Created with python_avatars 8-Bit Music´s says:

    i need one of those.

  20. Avataaar/Circle Created with python_avatars mdesm2005 says:

    traps for young players have been catching older players from time to time ….

  21. Avataaar/Circle Created with python_avatars Jan Dvořák says:

    Whoa. This has more RAM just to buffer the input than my desktop laptop has for the entire system.

  22. Avataaar/Circle Created with python_avatars CursosElectronica says:

    Make it 3ghz and on the US$1K mark and they might sell a few thousand units

  23. Avataaar/Circle Created with python_avatars Tanbir Sohail says:

    I can buy a car at that price… $6k
