Output Amplifier {Quality}

The output amplifier amplifies the collected charge from the output node and outputs
it as electrons/count. Although
amplifiers (i.e., one set at each end of the shift register,) some PIXIS systems are
available with a single output node and amplifier.
System with dual output amplifiers allow the output amplifier to be used to be selected
via the Acquisition

High Capacity Amplifier:
Provides a spectrometric well capacity that is approximately 3 times the well
capacity for the Low Noise amplifier selection. High Capacity is suitable when
you have intense light signals or signals with high dynamic range.
Low Noise Amplifier
Provides the highest sensitivity performance and is suitable for weak signal
applications.
NOTE:
The choice of Output Amplifier {Quality} and Controller
Gain {Analog Gain} settings should be considered together
for the best signal capture.
Examples of the interaction between output amplifier and
controller gain selections are provided in
