Near Field Probes 30 MHz up to 3 GHz
RF1 set
The RF1 near field probe set consists of 4 passive near field probes for making measurements in the development phase of E-field and magnetic field in the ranges of 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF1 set allow for measurements close to the electronic assemblies, e.g. on single IC pins, conducting paths, components and their connectors in order to localize 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.

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)

H-Field Burst Detector
BD 11
The BD 11 is used to detect a burst or ESD current pulse on a cable, for example in a complex system. This makes it easier to investigate the causes of sporadic faults in the system. It is small and handy, its sensitivity is very high and continuously adjustable.

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.

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.

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.
