P405/000/000 - Input Amplifier
This is our standard module for accepting signals directly from a photomultiplier in a multiple excitation system. In this mode the input is configured as a virtual ground, but it can also be configured as a voltage follower for connection to other photodetector systems, and the gain in both modes is internally programmable over a 100:1 range. The module integrates the incoming signal for each filter position, and the integrals are corrected so that they are independent of the rotor speed.
Up to four input modules can be supported by the modular spectrophotometer system. See also P405/OFF/000.
