Hi, All Gurus,
I dsigned a GSM module with 8W output.
Now I used a power supply for it, i.e. 12V/0.45A, that is stably displayed on the power supply, so I thought it was average current, 0.45A.
But now I want to test the peak current?
How to test it? Because GSM is pulse signal, so the peak current should be 8*0.45A, I only used one slot.
That should be calculated in theory.
But I need to test it, so how to do ?
Best,
Tony Liu
