    PDScope

    Chris,
    A few years back I bought a DPScope kit. Took the time to build it carefully. First time I turned it on, worked great! Got to use it 2 more times before it died. Next I went on EBay and bought a used Tektronix for ~ $180. Still using it. Yes it was more than I wanted to spend, but some things just don't pay to go cheap.

    You will want something that can take the transient spikes that we work with. You can't always predict the peak. I think the cheap, usb units don't have the protection.
    Take Care,
    Randy

      Hi Randy,
      I appreciate your honest reply.

      I have a friend who has an old Tektronix vacuum tube scope. He said he would loan it to me. I don't know if I have room for it? But, at least if it broke, it could be repaired, I think? At least, it would help me learn about scopes with real knobs.

        More feed back on the hantek from an EE at the OU.com thread
        from here

        It all depends on what you want / need.

        The cheapest serviceable scope going is the USB Hantek 6022. That is a two channel 20MHz bandwidth affair that can be found for around $75. Beware of knock-offs. It has far more features, better bandwidth, and comes assembled for less than the DP Scope. If you need more bandwidth for another $90. or so they offer the 50MHz 6052.

        If you need four channels the price jumps or you will have to go to used scopes.

          Thanks for the extra feedback from the EE at OU. I will assume he knows what is out there. If there was something that wrong with the software for the Hantek 6022, he would not have recommended it as the best lower end serviceable scope.

          So, If I have any money after New Years, this is what I will get. I do have a nice small laptop to dedicate as a PC scope.

          Thank,
          Chris

            The Hantek USB have no ground loop protection. So you have to be careful with them. I lost one from running a micro controller off the same (my only) PC. I lost the MC the scope and 4 of 8 USB ports on the PC.

            I never got any warning with the instruction. I guess I should have known the scope didn't have an isolated power supply, but I didn't and burnt a bunch of money up real quick.

            Cheers

              How does one calculate the oscilloscope frequency needed for any given expected waveform or events per second?
