  • shows OK digital signals up to 100 Mhz, menu quite intuitive

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    shows OK up to 100 Mhz digital signals,
    menu is quite intuitive
    (though reading the booklet is a must for some
    functions). The PrtScr button is a very quick
    way to get screen snapshot (settings values
    are shown nicely in same snapshot).

    Cons:

    1. The PC connection is not functioning at all:
    It came with CD with Chinese letters in file
    name, failed to install. I downloaded the app
    from UNI-T site, it opened, even showed the
    scope is connected, but nothing functioned
    (except a few knobs that turned around by
    my mouse - the rest stayed grey).
    Note it prevented me from verifying memory
    depth (cannot get the recorded signal into a
    file to check the ability to post-process)

    2. The screen is stated as 800x480 pixels.
    The snapshot provides a 400x240 BMP file. I
    suspect that the system resolution is half of
    the actual display and of the promise in spec.
    (probably memory / SW lack of support ?)

    3. A few more minor "expectation gaps"
    found comparing the user manual to the
    scope (e.g. missing "Video" "ALT trig" and
    "EXT/5" options in trigger menu)

    OtherThoughts:

    [ FYI The Model and version I checked is
    UTD2052CL, HW ver 2.00 , SW ver 1.09 ]

    4. For a person used to work with top of line
    D.S.O's, main feature I miss here is smarter
    trigger (especially smart pre-trigger chain,
    e.g. rise at channel 1, delay or events of of
    at least ... , and another rise on same
    channel) note that real power is achieved
    with 2nd channel and 2nd trigger level -
    requires more HW, maybe some
    improvements could be added just in SW)

    5. BTW I want to believe PC SW issue will
    be resolved. But if one builds expectations,
    then note that the SW offers only manual
    operation via GUI (mouse +KBD), while the
    "ultimate" testing needs the ability to access
    the PC SW from your own tester program
    (through FTP / ActiveX / ect...)

    Bottomline:

    At the time being, I believe it is the best
    standalone scope for its price, especially if you
    just want to see signals up to ~100Mhz and do
    not really need more than keeping snapshots of
    the screen.
