Setting the Attenuation
You can modify the power of the IQS-2100 Light Source output by
attenuating the emitted signal.
With some IQS-2100 Light Source models, the Attenuation control is
grayed out during the stabilization period, which occurs after you have
selected a wavelength if the source is activated.
To set the source attenuation:
1. Select the Instrument function tab.
2. Adjust the attenuation of the laser signal emitted by the source from
the Attenuation (dB) panel. For details, see Entering Values Using
Sliders and Numeric Boxes on page 15.
The attenuation value increases or decreases by increments of 0.1 dB.
