Near Field Probes 30 MHz up to 6 GHz
XF1 set
The XF1 set of near field probes consists of 4 passive near field probes and one passive E field probe for making measurements in the development phase of the magnetic and electric fields in ranges from 30 MHz to 6 GHz. Due to their integrated impendance matching, the probes are less sensitive in the lower frequency range than the RF type probes. The probe heads of the XF1 set allow for the step by step identification of interference sources of the magnetic field on an electronic assembly. At first, for example the XF-R 400-1 detects the fields which the assembly emits in total. Next, using higher resolution probes the interference sources can be more precisely detected. The E field probe is used for the detection of electric interfering fields near the assemblies. With trained use of the near field probes, field orientation and field distribution can be detected. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They have an internal terminating resistance.

Line-impedance stabilisation network
NNB 21 set
The NNB 21 line impedance stabilization network is designed for measuring of grid bound interferences of a device under test according to the satndard CISPR 25/ISO 7637. It measures the RF interference, which couples into the vehicle electrical system. Measurements during the development in a frequency range from 100 kHz to 1GHz can be carried out.

Scanner Probe
RFS set
The RFS set consits of three passive near field probes designed for the use in a measurement scanner during the development of E-field and magnetic field. They are designed for frequency ranges of 30 MHz to 3 GHz. The probe heads of the RFS set allow for close measurements needed to correctly localize interference sources on an electronic assembly. They document the whole image of the device under test`s near field. The scanner probes have a sheath current attenuation and are electrically shielded. They are connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance. The measuring signal can be increased with PA 203 or PA 303 preamplifier. On request RFS, LFS and XFS scanner probes can be produced.

Near Field Probes 30 MHz up to 3 GHz
RF6 set
The RF6 near field probe set consists of 2 passive magnetic field probes and 2 passive E field probes for measurements in the development phase of the E-field and magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF6 set allow a step by step localization of interference sources of the RF magnetic field and RF-E-field on an assembly. From a larger distance the electromagnetic interference is detected by RF-R 50-1 for the magnetic field and by RF-E 02 for the E-field. The RF-B 3-2 and RF-E 10 probes with their higher resolution can more presicely detect the interference sources of the magnetic field and the E-field. Field orientation and field distribution on an electronic assembly can be detected by special guidiance of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

Immunity Development System
Used for EMI suppression in printed circuit boards during the development phase. The developer can use the E1 set to quickly identify the causes of burst and ESD interference. This allows the developer to design suitable measures to solve the causes of the interference. It can also be used to test the effectiveness of the measures taken.

Near Field Probes 30 MHz up to 3 GHz
RF2 set
The RF2 near field probe set consists of 4 passive near field probes for measurements in the development phase of the magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF2 set allow the step by step localization of interference sources of the RF magnetic field on assemblies. From greater distances the electromagnetic interference can be detected by RF-R 400-1 and RF-R 50-1 probes. The RF-B 3-2 and RF-U 5-2 probes with their higher resolution can more precisely detect the interference sources. Field orientation and field distribution on an electronic assembly can be detected through a trained special use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

Near Field Microprobe E-field 7 MHz to 3 GHz
ICR E150
The near field microprobe is used to measure electric fields at extremely high resolution and sensitivity. The optimal distance to the object being measured is < 1 mm. Due to its small probe head dimension, the probe has to be moved by a manual or automatic positioning system, e.g. Langer-Scanner.

MP CI set
The MP CI set up to measure coupling impedance is used to determine EMC characteristics of connectors and cables. The coupling inductivity defines the coupling inductance of external disturbance on the shield or on the ground with the desired signals. If the coupling inductivity is considered in the construction set-up and the pin or wire assignment of connectors or cables, then the connectors or cables will be more interference-resistant. The MP CI set-up for measuring coupling impedance can be used for following measurements at connectors or cables: 1. measurement of a single signal (common mode) 2. measurement of a symmetrical signal (common mode) 3. measurement of a symmetrical signal (differential mode)
