POLARIS Trident Digitizer Sensitivity

File Sensitivity.pdf which is printed version of Sensitivity.xls shows Trindent digitizer bit resolution for varoious software gain settings.

For example, at a software gain of 1.0 and input voltage of 40 Vpp (typical of maximum-gain POLARIS station setup), the Trident resolution is 2.5 microVolsts / count.
