Cal Wavelength
The wavelength of the laser used to calibrate the sensor.
Wave Comp
Turns Wavelength Compensation On. The sensor responsivity is wavelength dependent.
Turning Wavelength Compensation On causes the instrument to restructure its internal
gains to compensate for the variation in responsivity.
Detector Size
The size of the detector used in the sensor. This is not the size of an individual quadrant,
but rather the total detector.
Sensor Responsivity
The responsivity, in V/J, of each of the 4 sensors in the quad. This data is stored in the
array memory and read by the instrument to be used for responsivity normalization.
% Absorption
The wavelength response, in % Absorption, of sensors in the array. This data is stored in
the array memory and read by the instrument to be used for responsivity normalization
when the sensor is used at a wavelength other than the calibration wavelength.
Port in Use
The Virtual Com Port in Use.
