Hi everybody,
first of all i just wanted to say that i'm not a electronics fan. Electronics makes me suffer. I hated analog electronics at the university, but now, I have to play with analog parts and even design some sensitive bits. My business is to detect relativistic ions passing though detectors. i had to design very low noise charge sensitive preamps. This works relastively well. I have to power my (200) preamps with +12V -2.5V rails in a very "dirty" environment : magnets, pumps, cavities : awful electro-magnetic place. I was using simple banana connections from my bench (agilent) low voltage power supply but the noise pick up was terrible. what i'm doing now is that i use banana to bnc adapters and transmit my low voltage through a good coax (lmr195). it works muuuuch better.
Now my question :is that a good practice or non-sense ?
thaks for your advices.
