[SI-LIST] Re: high frequency current measurements

The CT6 current probe outputs a voltage (into a 50 Ohm load) that is
proportional to the current in the sensor.  I don't recall the sensitivity
of the CT6 but you should be able to look that up yourself.  

Scopes are used to measure any phenomenon that can be translated into a
voltage.  Remember you will need to design an insertion point for the probe
to minimize parasitics.  You cannot just take a 10 cm wire and thread it
through the CT6 and expect to get any meaningful results.

Hi  ,
  I am doing some high frequency current measurements. What now I have is
the CT6 current probe and a oscilloscope. Is it enough to make the test
set-up ?

  My question is that usually the oscilloscope is used only for the voltage
measurement, not for current ? how can I deal with it ?

  thanks ,


best
