AGO Original Calibration & Formulas

Here is a sample of the original calibration worksheet with a description of the columns. The Lab section values are measured values and the Field section are calculated values based on actual receiver gain settings.


 

Calibration Formulas

Equivalent Electric Field Intensity (RMS) of an induced calibration voltage (balance injection) of Vcal, used for both lab and field:

Converting the lab value of Vcal to the field value:

Line Receiver Filtered Broadband output:

Filter Monitor output for the Hiss Filters:

Filter Monitor output for the TVLF Receivers:

Equivalent Electric Field Intensity (RMS) for the full scale voltage at the Line Receiver Filtered Broadband output (3 V peak):

Equivalent Electric Field Intensity (RMS) for the full scale voltage at the Filter Monitor output (10 V peak):
