I need to recognise some good computer softwares that i can use to model, simulate and measure my DIY electronic circuits if i can't have(afford) an oscilloscope to do so. Would you please name for me a few?

    Ltspice is a good start – alex.forencich Mar 22 '16 at 7:20
  • There are a few cheap USB ones available on ebay. You can use softwares like LTspice if you don't want to buy anything at all. There are always pros and cons depending on your exact purpose. – Whiskeyjack Mar 22 '16 at 7:21

    Models and simulations are a good start anyway, but what you really need a 'scope for is figuring out why your real circuit doesn't behave like the simulation. If you are a student, Analog Discovery 2 has discounts, which may be worth investigating. – Roger Rowland Mar 22 '16 at 7:34

    If you have a PC that is available for your own use you can use the sound card as a low frequency oscilloscope. | You can get very low cost basic oscilloscopes from China. How much can you afford to spend on an oscilloscope? ($ 1 2 4 8 16 32 64 128 ?) | What country are you in ?- may affect advice greatly. | Do you have a laptop or desktop PC of your own? If so what brand and model? – Russell McMahon Mar 22 '16 at 8:29
  • As mentioned above LTSpice is a good one, although it all depends on how complicated the circuit is. If I'm just building a small circuit with a couple of transistors I usually just use Falstad – Hayman Mar 22 '16 at 8:47

You can use Proteus software which good one

    While this certainly is more than 15 characters on Stack Exchange we generally prefer people to explain their answer in at least a few lines. Why try that? What does it do? Maybe add a link. – Asmyldof Mar 22 '16 at 9:00
  • I'm not sure if Proteus can really do any kind of analysis, and I guess it's often used for Modeling and Prototyping, are you sure about what you suggested?? – M-J Mar 23 '16 at 12:07
  • @M-J Yes Proteus can be used for simulation and modelling.Cant use for measuring . A computer based (low cost) oscilloscope cant support high bandwidth . allaboutcircuits.com/textbook/experiments/chpt-4/… Use USB based Oscilloscope .. – Gireesh Kumar Mar 23 '16 at 17:01
