Summing module S2
This module contains no electronics but functions as a "patch area" for the user. All control inputs of the source/measure modules can be connected to signals from the iso-amp-in module or/and the D5-DAC module (via patchchords inside the module). All the (8/16) DACs have also an output on the front panel (note that the DACs themself are located in the D5-module). Other functions of S2 are: DAC-filtering/summing/dividing. Different front panels are possible to adress connector preferences. Standard frontpanel is S2d (or S2f with added resistors)
