Gigahertz-Optik X1-RM Optometer respectively Current Amplifier for Radiometric or Photometric Applications

-Measurement range:

Wide dynamic current measurement range from 0.1 pA (noise equivalent signal) up to 200 µA. Seven gain ranges with manual or automatic selection. Measurement range in absolute units with given by the detector heads responivity and calibration. 

-Typical applications: Measurement device for system integrations.  


Calibration and comparison of the current responsivity in each of the seven gain ranges. Memory for calibration data of several detector heads for measuremen in the absolute unit of the selected detector head.
