    I'm also looking for a scope but have some requirements

    I'm in the market for a good reliable scope but I have some basic requirements
    for troubleshooting old x-y vector monitors and game boards. If you have a
    good suggestion please include brand and model number. I have $1500 to send.

    ATARI REQUIREMENTS:

    - at least 50MHz
    - dual trace
    - 5mv per division or better
    - vertical sensitivity (rise-time capability) of 5ns or less
    - internal synchronization features
    - an internal and external sync feature, along with delayed sweep
    - and a Z-axis input

    So, what do you guys think?

    I know this doesn't answer your question as in "make model price"
    but hope it helps anyway


    New or Second hand?

    scopes that were worth a fortune can be had quite cheaply now.
    TeKtronics is one to look at I have seen many $$$ for a lot less $$$
    BUT having said that. you may have problems with older ones if you need parts
    I am talking the old CRT jobs but have seen the LCD type ones.
    lest wise what I see on Ebay
    there are companies that deal in second hand tech stuff too


    Another possibility is scopes with storage
    (capture a sample of the waveform)

    I an not up on what available these days if you in the market for a new one
    most are now the LCD (using the term loosely here) storage type things.
    that do have possible draw backs (DSO)

    these are discontinued models at tek here
    that you might get second hand for a reasonable price
    (just beware of replacement parts availability)

    site link if you want to have a browse around on the new stuff

    http://www.tek.com/products/oscilloscopes/

    Who makes a decent scope at a good price these days I don't know

    There are also scope box type things (and SW)
    you can get for use with computer but got no idea on what they are capable of specs wise
    (I am thinking not much really but could be wrong
    Someone may actually make a high quality digital storage box
    (read as CRO without a screen),
    its really only a matter of sending the sampled info to a computer)


    Cheers

      New or used doesn't matter I have 1500 to spend. Everything you mentioned Starfury1,
      I already know. But, I don't know what scopes out there have all the requirements I need.
      Some new scopes don't even have a Z-axis input.

      I was hoping to get a reply from someone who knows what BRAND & MODEL to buy that
      doesn't have model specific flaws or failures but yet has the requirements I need in a scope.
      I don't have the time to research tons of scopes to find what I need. I was hoping someone
      out there might have the 10 or 20 years of using scopes who would know what's out there
      and what's reliable.

      My luck, I'd spend weeks researching info on various brands/models and then purchase one
      only to find out the one I chose as some quirky messed up inherent problem, there are some
      scopes out there like that. If anyone has a suggestion on a BRAND & MODEL that would be great.

      ATARI REQUIREMENTS:

      - at least 50MHz
      - dual trace
      - 5mv per division or better
      - vertical sensitivity (rise-time capability) of 5ns or less
      - internal synchronization features
      - an internal and external sync feature, along with delayed sweep
      - and a Z-axis input


      Thanks again guys,

          yeah wish I could have had a more direct answer for you.

          The above does sound like a good deal though
          (I wouldn't say no )

          Tek should serve you well from the quick look at the specs , its an older model
          Hope its a well care for unit for you too.



          let us know how you go

          Cheers

            Looking at eBay there are several of these scopes available. Lowest price being $249.00 without probes or manual. Others with all goodies up to $500+. So the deal you quote sounds very good.

              Reading input and output of bridge rectifier on the same scope?
              by EasyGoing1
              I have a 40 volt AC transformer that I put a bridge rectifier on, and I wanted to see the input signal and the output signal on the same screen on my scope, so I set one channel up with the test lead on one side of the input and the ground lead on the other side of the input, then I used another channel on the scope and clipped the test lead on the positive side of the output then the ground on the negative side of the output.

              When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier...

              Another Kenwood CS-4035 question
              by Crystaleyes
              Need a hand understanding how to read a part of the schematic.

              So, as reported in the earlier thread, after repairing the KMA-01 hybrid IC on the PSU, the scope came to life without any issues other than calibration.

              There were two of these scopes in the job-lot however, and the 2nd one also had the same bad IC on the PSU which was repaired in the same manner. This 2nd scope also had some missing transistors on the main board, which only arrived yesterday, and unfortunately, installing these components hasn't helped to resolve the lack of trace on the CRT. I know the...

              by definitely not an expert
              I have been given a metex ms 2000 handyscope to use for fault finding.

              It works but the 30 year old battery pack is no good, i have purchased the new correct batteries, tryed to put it all back together but couldnt get get continuity between the four 1.2v batteries, upon checking one of the components, a thermal fuse has blown i think.

              now the issue is that I dont know what the part is, how to work out what it is and were to buy the components.

              Im looking forward to getting it going so if anyone could help that would brilliant, and would certainly make my...
