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.

Micro probes 1 MHz up to 6 GHz
MFA 01 set
The micro probes are used to measure magnetic fields and they have a high resolution. They measure magnetic fields up to 6 GHz, e.g. at signal conductors (150µm), SMD components (0603-0201) or IC pins. The MFA micro probes are guided by hand. An amplifier stage is integrated into the probe head. The amplifier stage (9V, 100mA) is powered via the Bias tee BT 706. It has an impedance of 50 Ohm. The micro probes are connected via the Bias tee BT 706 to a spectrum analyzer or an oscilloscope. Langer EMV-Technik GmbH includes correction lines in the delivery. With the help of the correction lines the probe output voltage is converted either into the respective magnetic field or to the current which is running through the conductor.

Near Field Probes 30 MHz - 6 GHz
XF Family
The XF family consists of 4 passive magnetic field probes and 3 passive E field probes designed for measuring magnetic and E-fields in ranges from 30 MHz to 6 GHz during the development phase. Due to their integrated impendance matching the probes are less sensitive in the lower frequency range than the RF type probes.

Measurement Technology for Teaching and Training
Is particulary suitable for training and further education. With the disturbance emission model, a variety of different experiments which improves one`s understanding of electromagnetic processes in modern electronic engineering are possible. The coupling mechanisms of disturbance emissions are visualized from their sources to the antenna. The impacts of EMC measures are then easier to understand. At VM 251 the electromagnetic d

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)

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.

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.
