Measuring pickup impedance response.
Hi, just curious if anyone has any suggestions for measuring the impedance of the pickup and cables. I was thinking of just passing in frequencies thru an audio jack and measuring the voltage across a known resistance to get current with a scope. From there I can find the impedance by measuring the voltage across the jack leads, as V/I for that frequency.
Any thoughts? Thanks, JP Last edited by jjmuggs1390 : 12-10-2012 at 06:19 PM. |

All you want to do is check how many ohms the pickup is. Connect it to the 2 ends of the pickup, and it should show up something from 5K ohms to 11K ohms, depending on the pickup.

That's just the DC resistance. I'm talking impedance. |
