NI new power calibration
Alessio Thu Dec 11, 2008 6:58 pm
Since yesterday we noticed that the power of the NI bench is rather noisy (see EGO logbook entry 21486), we decided to change the range of the power meter from 3W to 300mW. This operation required new calibration of the transmitted power (power of the annulus impinging on the NI TM) versus the voltage acquired by the ADC.
The new conversion equation is:
PNI(W)= - 0.074+6.111*(V1:Pr_TCS..NI_Power_MEAN)
The new conversion equation is:
PNI(W)= - 0.074+6.111*(V1:Pr_TCS..NI_Power_MEAN)
