The NSG 223A module generates high energy pulses typicai of Those produced by switching Inductive and capacitive loads, lightning strikes, etc. The pulsescan be symmetrically or asymmetrically superimposod on the mains supply by means of the coupler in the main-frame as well as being available via separate sockets for component testing purposes. Because of their relatively high energy of about 2 Joules, the pulses can result in damage to unprotected or unsuitably arranged elements in input circuits.
This type of pulse is defined by varlous standards. IEC 801-5 among them. Compared to this specification, the NSG 223A generator has a some what higher internal impedance of 45 Ohm in keeping with the wishes of many instrument manufactures and test departments to overcome the danger of stressing components too much.
