Setting the Attenuation
Setting the Attenuation
You can modify the power of the IQS-2150 Light Source output by
attenuating the emitted signal.
With some IQS-2150 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.
Note:
When a multimode source is used, the attenuation value increases or
decreases by steps of 0.5 dB. With a singlemode source, the attenuation
value increases or decreases by steps of 0.1 dB. The attenuation is not
possible when the modulation mode is used.
