Detector / Integrator Stage

The detector / integrator input/output relationship was not included in the original calibration worksheets so a lab
test was performed and results were compared to field meaurements made in 1997.
 

The Integrator / Detector has an output range of approximately +/- 8 V, and inputs larger than ~8V cause saturation. In the linear range, the relationship between the Filter Monitor output and the Integrator / Detector output is:

When using the Filter Monitor RMS value, it becomes:

 

The 1997 field measurements agree reasonably well with the lab measurements:
