3. Scope of Delivery
SF 11 –
Demo Board Immunity B-Field
NT FRI EU –
Power Supply Unit
SF 21 –
Demo Board Immunity E-Field
Short Description
The SF 11 demo board is a board on which interfe-
rence effects such as burst and ESD due to mag-
netic field are demonstrated.
The interference can be generated e.g. with burst
generators, ESD generators, the E1 Immunity
development system and field sources from Langer
EMV-Technik GmbH and thus illustrate their opera-
ting principle.
Technical Parameters
Supply voltage
12 V
Current input
ca. 20 mA
Sizes (L x W x H)
(140 x 100 x 23) mm
Technical Parameters
Output voltage
12 V

P11 –
Mini Burst Field Generator (B)
P21 –
Mini Burst Field Generator (E)
Short Description
The P11 mini burst field generator creates a mag
-
netic disturbance field with a diameter of approx.
3 mm at its tip. Localized pulses can be transmit-
ted via this field onto the surface of printed circuit
boards and components allowing for weak points
such as the sensitive parts of conducting paths,
components and component connectors to be
detected.
Short Description
The P21 mini burst field generator creates an
electric field at its tip, which is suitable for coupling
into conducting paths, wires, pins, and components,
especially SMD components like resistors and
capacitors. Single conductors of flat cables or plug
contacts can be also tested.
