[SI-LIST] Re: high frequency current measurements

Junfeng,

I think you can find the answer in the operation mannuals. Firstly, you need 
to check the frequency band of these equipment  to make sure that they are 
suitable for your use. Then find the transfer impedance (Zt)of the current 
probe which I think should be provided in the mannual. If some other 
correction factors are not specified by the mannual, generally, the current 
can be obtained from the voltage you measured with the oscillosope by the 
relationship I=V/Zt in linear scale, or I=V-Zt in dB.  All equipment 
manufacturer websites provide technical support for their products.

Regards,
Celine
