P11 – Mini Burst Field Generator (B)
P21 – Mini Burst Field Generator (E)
Short Description
The P11 mini burst eld generator creates a mag-
netic disturbance eld with a diameter of approx.
3 mm at its tip. Localized pulses can be transmit-
ted via this eld 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 eld generator creates an
electric eld 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 at cables or plug
contacts can be also tested.

The EMC-Basic 1 set contains modules for demonstrating immunity and emission phenomena.
The EMC-Basic 1 set is powered by the supplied power supply.
4.2 Reasonably Foreseeable Misapplication
Incorrect application of the EMC-Basic 1 set may result in danger to the user, damage to the product
and/or connected devices.
Examples of incorrect applications that can lead to danger:
- Safety devices are bypassed or disabled.
- The devices are not in a proper technical condition during operation.

4. Safety
5.1 SF 11 - Demo Board B-Field Immunity
During immunity tests, interference pulses are often fed into the devices or assemblies to be tested
via cables. This results in interference currents within the assemblies, which are always associated
with magnetic elds (Fig. 1). Depending on the layout of the assembly, these elds can induce
voltages in signal conductor loops and thus generate functional errors.
In order to nd the causes of functional errors, it is important to determine where sensitive signal
conductor loops are located on the module. The P11 pulser is used for this purpose.
It generates a small-scale magnetic eld at its tip. This is used to simulate the magnetic eld
generated during an immunity test according to the standard in a very small area. To do this, the
switched-on pulser is moved by hand over the assembly (Fig. 2). If there is a sensitive signal
conductor loop below the pulse tip, the DUT generates the same functional fault as in the immunity
test according to the standard.
5. Test Procedure
Figure 1: SF11 with interference current and magnetic eld with two cables connected
Figure 2: P11 pulser is guided over the SF11 demo board

In the case of the SF 11 demo board, a gap in the GND surface deliberately allows magnet eld to
pass through the module between the signal line1 and GND. A functional error occurs - the relay
rattles. The path of the magnetic eld lines is shown in Figure 3. (If this test does not lead to a
functional error, the polarity must be changed at the pulser).
The coupling can be prevented by a „shield“ made of adhesive copper tape: the magnetic eld is
blocked by the eddy currents within the adhesive copper tape. The magnetic eld can no longer
penetrate the assembly, and the SF 11 is immune to interference.
Alternatively, the line „Signal2“ can be activated by switching the switch S2. This line is completely
surrounded by GND and deposited in the inner layer with GND. Almost no magnetic eld can reach
around the signal line, the assembly is much more resistant to interference (Fig. 5).

Figure 4: Improving the immunity with a piece of adhesive copper tape
5.2 SF 21 - Demo Board E-Field Immunity
If only one single cable is connected to an assembly, the result is a eld image as shown in Fig. 6.
The interference current ows into the module, but couples out again capacitively as an electric eld
(electric ux). This decoupling is done from the GND area as well as from all connected components
and lines. The current decoupling from the signal line in Fig. 6 generates a voltage difference at
resistor „R“ (This resistor symbolizes the output resistance of an IC output.). This voltage difference
can lead to the functional error.

The descriped electric elds can be generated locally with the P21 pulser. If it is guided over the
module near line „Signal1“ as shown in Fig. 7, electric eld couples directly into the signal line. A
functional error occurs - the relay rattles.
If the P21 pulser is moved across the board in the vicinity of line „Signal2“, the interference is much
less, since a large part of the electric eld does not couple into the signal line, but into the GND
surface in the immediate vicinity (Fig. 8).
