    Dave, I love your longer videos, Why do you always want to keep them short for our sake? The more you blabber, the more I pickup and learn!

  • @bdivi2000
    @bdivi2000 10 років тому +6

    Question is about the rise time of the function generator source. If the rise time of the source is limited (which I see in the AWG datasheet as 8ns) then of course the performance of the two probes will be identical - they have 2.3ns and 0.9ns respectively. You have to test them with rise time that is close to the rise time of the scope (which is 3.5ns) in order to see a difference.
    The test with 8ns rise time pulse under these conditions is meaningless.

    EEVblog I just want to make a humble request if you can make a series of Basic or Fundamental electronics lesson for a beginner like me? I missed your Fundamentals Friday video. I always watch the video you have uploaded even though I don't understand them because it is so advanced for me and the others out there. You have a lot of viewers,many of them have an advanced knowledge while some are just beginner like me. Please consider also our level to your video contents and not always to the advanced viewers out there. :) Thank you.

    This is actually a good show format for learning... you get the best of both Dave's EE experience and rant enthusiasm

  • @emilybjoerk
    @emilybjoerk 7 років тому +10

    So you used a 150 MHz BW and a 300 MHz BW probe with a 1 GHz BW scope without the input LP enabled and saw no difference in the step response. That means one of two things: both probes have the same actual bandwidth (which is entirely possible they are just marketing one as worse than it actually is) OR your test signal doesn't actually contain any high enough frequency components to make your test valid.

    • @gblargg
      @gblargg 6 років тому +2

      My thought too re: test signal might not contain harmonics at the frequency. Seems a much simpler test would have been a 100 MHz sine, then measure amplitude.

    • @szabolcsmate5254
      @szabolcsmate5254 5 років тому

      I agree. Pretty useless experiment. am sure he has a better step signal somewhere, if nothing else he could have hunted one down with that 1GHz scope and then do the comparisons.

  • @fuzzy1dk
    @fuzzy1dk 10 років тому +6

    you could have compared with the waveform when using just a 50R cable from the generator and termination at the scope, to see the best case

    • @fuzzy1dk
      @fuzzy1dk 10 років тому +6

      MichaelKingsfordGray
      _termination at the scope_ if the scope doesn't have 50R termination use a feed-through terminator

    @thommw 10 років тому +3

    You can actually use the REF function to compare signals. Very handy for stuff like that. :) I also would have liked to see a comparison with a super-duper Tek probe.

  • @tkarlmann
    @tkarlmann 9 років тому +3

    I think Dave was trying to assure everyone that the Rigol probes are good. No problem. I think the comparison test was a waste of my time, in that Dave could have EASILY measured the Risetime of each probe on each scope. Dave was being qualitative -- I would have done risetime measurements

  • @rhost714
    @rhost714 10 років тому +1

    My DS2072A came with RP3300, but they are a fixed X10 with the short ground lead so they have definitely changed the probes over the years.

  • @DaveMueller1980

  • @bibiricat
    @bibiricat 10 років тому +3

    Dave, do a tear-down of a passive and active oscilloscope probe please. You always do tear-down of oscilloscopes, but never voltage or current probe.

    • @jacobamador7989
      @jacobamador7989 Рік тому

      Teardowns of probes are often destructive. Nobody wants to ruin a 2k fet probe.

  • @sbreheny
    @sbreheny 10 років тому

    Dave - I think that the system BW formula you used assumes a particular probe and scope transfer function - I think 1st order.

  • @longjohn526
    @longjohn526 7 років тому

    Rigol seems to have changed the probes on the DS1054Z because mine (which arrived a couple of days ago) are completely different .... slightly different BNC connector ..... The X10 switch is recessed and works in the opposite direction, up is x10 and down is X1 and the cable is apparently a different length. ..... Also the flared end of the hook adapter is slightly larger in diameter. I found this out printing a scope probe case from Thingiverse and nothing fit right.
    You may need to retest to verify they are just as good

  • @trahim2
    @trahim2 10 років тому +1

    My DS2072 came with the 3300A probes. They're far nicer than the 3300 you've shown. Maybe some units are shipping with different probes?

  • @PilotPlater
    @PilotPlater 10 років тому +2

    Good video Dave. What do you reckon is the cause for the difference in the signal the poster observed? maybe the "antenna ground lead"?

    • @EEVblog

      Andy Plater I'm at a loss to explain apart from probing differences. Seems he still thinks there is a difference.

  • @38911bytefree
    @38911bytefree 10 років тому

    This ringing cannot be compensated at the probe. You compensate the probe as ussual, with 1Khz zoomed out and the zoom deep in and see all the overshoot thing. Curious ir this can be eliminated by fine-tunning the probe (tunning it even more). Great vid.

  • @WieEiPiehGuy
    @WieEiPiehGuy 10 років тому

    Hi Dave, I'll try again: I'd appreciate it if you could do a video (or more ;)) about spectrum analysators. Explain RBW, VBW, zero span, a few words about dB/dBm/dBµV.. and terminology like that and how to generally use those (expensive) devices. Cheers.

      If you spend hundreds of hours making quality videos and post them on youtube then people will send you some to use or demo for free but it may be a lot less work just to save up and buy a 1054z

  • @MichaelEC1
    @MichaelEC1 7 років тому

    New to this scene but I picked up a Rigol DS1054Z (100MHz Mod) and it came with PVP2150 probes. Well I am taking a semiconductor course and I am here at home working on a self biasing transistor circuit. Well hooked up my scope and PVP2150 leads to get a Vin/Vout Sine-wave. Had my Signal Generator set for .03V at 1kHz. Well the sine-wave on the screen was all over the place. Could not even read it, it was so jittery. So I hooked directly from generator to scope with a direct BNC to BNC cable. No jitters at all. SO I am thinking, could it be the probes. So I picked a set of RioRand P6100 for Semiconductor Lab, they don't supply you with leads on their scopes. So, hooked up the RioRand P6100 on the Rigol DS1054Z scope and no jitter. They work great. So make me think are the new probes their supplying crap!?

  • @farzadb82
    @farzadb82 10 років тому

    Hi Dave. Not sure how much this matters, but I noticed that the scopes you'd tested with were set for 1x. I believe this was consistent across all the scopes used, however.
    Other than that, great video.

  • @JAKOB1977
    @JAKOB1977 3 роки тому

    Not many scopes seem to give the full control over the bandwidth 8:57 or are there another option that makes you ask for the bandwidth value you want.
    On my unit from Micsig.. I got the normal full BW and the 20Mhz and then high and low pass where I can set the bandwidth as I want on all the 4 channels... and do like that as it gives me good control over the noise... you got full control from 30KHz as I recall and up.

    find that quite useful for many of these el-cheapo AC/DC current clamps when you have the scope in amp mode and where some of them have a lot of noise when you're down in lower DC current levels..
