Hii.....
i m stuck somwhr in my project, and ur valuable opinions and suggestions are invited.....
Brief about Project:
I hav to acquire sensor data from a system which is terminated in 10MOhms. i have to use a cable (may be triaxial or coaxial cable) to connect it to my signal conditioning card.
a. signal level is +/- 100V and +/- 100mV
b. frequency of signal is 1kHz to 100KHz
c. magnetic field of 20Gauss arround the system giving di/dt= 10KAmp/sec
Issue:
i have to match the impedance of the sensor card impedance, cable and my signal conditioning card impedance.
Que 1. do length of the cable make any difference in impedance matching.
Que 2. what i hv to do for impedance matching?
Que 3. does magnetic field of 20Gauss affect my system? how much? how can i avoid it?
please let me know if any other details required.....
Thanx.....
Cheers...
