LeCroy or Tek scope?

    It's time for a new scope at work. My budget allows for either a Tek
    TDS5054B or a LeCroy Waverunner 6050, however I have a hard time to make
    the final decision. Both scopes are certainly very good ones and both
    seems to be well suited for my purposes according to their similiar
    specs. I do "general" design work with quite different objectives (e.g.
    uC, analog, mixed-signal stuff) which does not emphasize a single key
    feature, which would make a decision easy. I'm looking more for a
    "Jack-of-all-Trade type" scope.
    I were able to play with both scopes for half an hour, but this didn't
    really help me, because naturally in this time frame you can only
    scratch the surface of the feature set or the user interface. Does
    anyone like to share his/her comments on those scopes - subjective
    opinions are welcome.

    Thanks in advance

    I've worked with a waverunner and some TEK scopes but found that the LeCroy
    was faster with changing the timebase and it reacts faster when pressing the
    buttons. For the rest it are good scopes.

    I have my own reasons for disliking LeCroy, so I can't comment on
    their scopes. But I have a TDS5052, and everybody here loves it. The
    DPO stuff gives it a very nice "analog scope" feel. Their 1 GHz FET
    probes are very nice, too; get them if you can.

    Don't forget to check the guarantee period and how much it costs to repair,
  5. Who/what the hell is LeCroy? Never heard of 'em. :-|
    What's wrong with Anritsu or HP?
  6. There's nothing specifically wrong with Anritsu and HP except they don't
    make scopes.

    I'm certainly not current on 'scopes, I have a 20-something year old
    Leader and a several year old Tek TDS210. But hp for sure made
    'scopes back in the '60's thru the '80's. I know, because when I was
    in a position to influence 'scope purchases I forbade the purchase of
    hp 'scopes because of their poor triggering.

    We demoed an HP scope that had, like, 4 buttons. The menus were so
    complex we couldn't get it to do much of anything.

    I think the current-generation Agilent scopes are pretty good... lots
    of knobs and buttons like God intended.

    HP scopes are now Agilent - so strictly speaking HP doesn't make any
    scopes anymore, although I guess most of us still regard Agilent and HP
    as the same thing, when it comes to electronics instruments.
    Agreed! The scope I'm going to buy will replace one from HP, which I
    really learned to hate during the recent years :-(

    HP is now called Agilent ;-) They have also some nice scopes, a few of them have
    have also digital inputs with logic analyzer functions.

    When did HP stop making scopes?
    I believe you're wrong with this statement.

    Another one of HP's many claims to fame (which has always struck me as
    one of the slickest tricks ever) was the invention of the internally
    deposited graticule, which totally eliminated parallax. Can you
    imagine the OMIGOD!'s at Tektronix when it hit the street (as I
    recall...) in the sixties ?
  13. When they spun off Agilent.
    I'm quite confident I'm not.

    I am regularly frustrated by slowness of older Tek scopes. But I have
    been using the DPO TDS3000 series for some time, and they don't have
    this problem. They are even more responsive in the newer TDS3000B
    series, so hopefully the TDS5000 series that the OP is considering is
    peppy as well.

    Good day!

    Correct me if I'm wrong, but didn't you just post a couple of months ago
    at which point you had never even heard of Anritsu?

  16. I've never used the newest Tek 50xx series, but I'me using a quite old
    Lecroy scope (9350) for years, and when comparing it even with TDS30XX
    scopes I will never accept even a swap : The Lecroy used to have far more
    sophisticated triggering modes, as well as a very high reactiveness. To be
    checked of course with the new models...

    Aged scope user with recent experience of Tec & LeCroy.
    I still prefer CRT analog for analog use, digital scopes still are
    "challenged" by the need for a/d that has lots of bits and GHz bw , this
    is not easy and the result is noise of 1mV or so on a channel with 10V
    max signal.
    Anyone disagree?

    Depends on what you're doing.

    For repeating signals at reasonable high frequencies, analog (i.e. true
    analog) is good.
    But for slower signals, especially at unregular repetition rates, and
    for "single shot" ovservations you really need a DSO.

    I am using a analog/digital scope, and most of the time I have the
    storage turned on since it's better for the signals I deal with.

    Their logic analyzers may have been just as complex, control wise,
    but I have nothing to compare to. The HP Calan sweep system was a
    complicated menu system in comparison with Wavetech Stealth.

    I was impressed with LeCroy. I had a 700 MHz LeCroy and a 1 GHz HP
    DSO at my disposal. Aside from the HP's storage capability, which
    did come in handy once or twice, the LeCroy blew the HP away.

    And the HP wasn't as easy to figure out as the LeCroy, either.
    God? Good ol' design?

    Well- I don't- the models you refer to are too new for any direct
    experience- but I do have the very high end of both Tek and LeCroy. Tek
    is absolutely right in saying their GUI is intuitive- you can start
    using that scope right away, the performance and features always work as
    advertized, they are usually shy on acquisition memory so that 8Mb they
    advertize will cost you extra, and the glitch capture, programmable
    logic triggering, and direct compatibility with their logic analyzers
    makes this scope the best choice for digital and mixed signal. LeCroy
    oscilloscopes, on the other hand, are an evolution of their CAMAC crate
    digitizer mentality and are not optimized for this kind of
    application. Another constant with them is that their internal control
    "ROM" will be in a state of upgrade flux throughout the product
    lifecycle- they will only tell you about this when you run into a
    problem. The packaging does not seem to be as durable as Tektronix- we
    shipped a LeCroy via UPS once, in a really rugged box bolted into a
    shock spring mounted 19" half rack- the LeCroy internal power supply
    came loose and smashed the CRT. Tektronix and Agilent do not seem to
    suffer problems like this.
