    Old OScope - Worth 100$?

    Navadeep Ganesh U

      I have an option to get this scope for 100$! Worth it? I am a newbie and help me make a decision.

      My Usage: Student and Hobby Projects, Basic T&M.

       

      APLAB 5 IN 1 TESTLAB 3744

       

      Features:

      • Comprises of Several Instruments in One Package Dual Trace Oscilloscope, Component Tester/Comparator, Triple Output DC Power Source, Frequency Counter and Function Generator.
      • Oscilloscope with dc to 30MHz Bandwidth and 1 mv/div Sensitivity on Both Channels.
      • 140mm Rectangular CRT and 8 x 10 cm.
      • Display with Internal Graticule. 40ns/div to 0.2s/div Time Base.
      • Z Modulation (TTL Level). X-Y Operation.
      • TV Triggering Frame (V) & Line (H). LINE Trigger.
      • Component Tester / Comparator for Quick Evaluation of Component Characteristics.

          Hi Navadeep,

           

          I think you'd have fun with it, I used my first CRT-based 'scope a lot too.

          However, I cannot see from the document, but I think it is not a storage 'scope. This will make it hard to use for many experiments with (say) digital technology or microcontrollers. My first CRT scope was a storage one, and I used that capability a lot. So personally I would not get this APLAB 'scope.

          Another option (similar cost) is Picoscope 2000 series. I have the model 2205A, it is still quite basic, but it can store traces, so it's useful for looking at digital signals like I2C, UART and so on, as well as analogue signals. It has a signal generator too. As an idea, you could enter some Project14 competitions, and if you win, spend your prize on such a 'scope.
