If the electric field couples into the cable network of an IC to be tested, the voltage of the connected impedances will drop. This voltage drop applies at the IC pin can lead to interferences.
The coupling behaviour can be simulated by a high- ohm pulse voltage source. Therefore the P311 has a high internal resistance. The pulse voltage is adjustable in the range ± (5 - 140)V.
The probe is operated by the BPS 201 burst power station and the BPS-Client control software.
The measuring station of the IC to be tested needs the ICE1 test environment. Depending on the measuring task additional equipment is required (oscilloscope, PC).
