System Interference Simulator
The circuit elements that are used for all types of interference simulation are placed in the main frame. These elements are the different mains filters, line switches and fuses. In operation the main frame must be connected to the line voltage (110/120 Volt, 60 c/s) through the line cable. This line voltage will operate the electronic circuits and - if the main switch is on position "on" - it will appear at the terminals L, N and Gnd on the front panel of the instrument with the proper interference added to it.
