6. Calibrate power meters
7. Detecte the frequency response bandwidth

 

• Calibrate current transducers by direct measurement method

 

☆ Calibrate current transducers by the comparative method

1. TA1200 can output a constant high frequency current signal, used to calibrate current transducers through comparing the measurement difference between the high frequency coaxial shunt and the detected current transducer.

• 
  Detect frequency response bandwidth characteristics of the sense current transducer

1. Outputing high frequency current signal to detect the frequency response bandwidth performance of the current transducer.
