XL741 Discrete Op-Amp Kit how to measure the open loop gain in its bandwidth, its frequency response

[jc_insco]

Hello I am a beginner in electrical engineering, and I bought the XL741 OP amp kit, forgive my ignorance since I am trying to learn OP amp basics and applying in real life in the Kit.  My questions are,  How do you measure the open loop gain in its bandwidth ,its frequency response, the voltage gain of each stage, and the input and output impedances?  Mathematically and especially in real life?  Thanks for all the help.

Use the same techniques that you would with any other op-amp.  The hard part is usually understanding what each of those terms really mean in the real world– once you do, it becomes somewhat reasonable to start to design your own tests with them. You might start with a few separate Google searches on how to measure those values.  

Here are some starting points for you:
