| Schaffner NSG200D 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.
