The Wave Electric Field Intensity is converted to a voltage at the preamp based on the parameters of the loop antenna:
The Line Receiver has an internal gain as well as a front panel adjustable gain:
The Filter stage also has an internal gain and adjustable gains:
The Detector/Integrator stage outputs a DC
voltage with a level shift:
The output is then digitized to a 12-bit number:
Making the following substitutions:
The original Wave Electric Field Intensity can be determined by putting all the stages together:
A simplified formula shows the linear relationship between the digital output and the electric field:
