For example, if there were a large amount of 60 Hz, power-line noise being picked up
by the module wiring, setting this value to 16,667 uS would virtually eliminate all 60 Hz
noise. However, all data sampling on this channel will be much slower. Larger values
could prevent the system from sampling at the nominal 1 second interval and will
certainly greatly increase the time required to take IV curves.
Larger integration periods can be helpful if illuminating the module with an artificial light
source powered with an AC power source. For example, some artificial light sources
use AC power with frequencies that cause the light to fluctuate at a frequency of 400
Hz. In that case an integration period of 2,500 uS would ideally eliminate the noise at
this frequency.
Aperture & Total Area
These values are for convenience and are used to calculate the modules electrical
efficiency based on the irradiance 1 value associated with this module. The efficiency
values are only recorded with IV curve data. These values have no effect on any data
recorded other than the associated efficiency values. These values are often not used
and therefore these settings may be left at their default values.
