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 100 kHz up to 50 MHz
LF1 set
The LF1 near-field probe set consists of 4 shielded near-field probes used during the development process for emission measurement of longwave, medium wave, and shortwave frequencies on electronic devices. The probe heads of the LF1 set are designed for incremental detection of sources of electromagnetic interference on assemblies. First, the electromagnetic interference of the assembly is detected by the LF-R 400 probe from up to 10 cm. Then probes with higher resolution like the LF-B 3, LF-U 5 and LF-U 2.5 are used to more precisely detect any source of interference. The probe heads are designed for taking measurements at single pins and larger components. Near-field probes are small and handy. They have a current attenuating sheath and, therefore, are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The H-field probes do not have an internal terminating resistance of 50 Ω.

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.

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.

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.

Micro probes 1 MHz up to 1 GHz
MFA 02 set
The two in the set included micro probes are used to measure low-frequency magnetic fields up to 1 GHz, e.g. at signal conductors (150µm), SMD componets (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 BT 706 Bias tee. It has an impedance of 50 Ohm. The micro probes are connected via the Bias tee to a spectrum analyzer or an oscilloscope. The MFA 02 set delivery of Langer EMV-Technik GmbH includes correction lines. 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 1GHz - 10 GHz
SX set
The SX1 set consists of 3 passive near field probes for making measurements in the development phase of E-field and magnetic field with a high clock frequency in the range from 1 GHz to 10 GHz. The probe heads of the set SX allow for measurements close to electronic assemblies, e.g. on single IC pins, conducting paths, components and their connectors, to localize interference sources. Field orientation and field distribution on an electronic assembly can be detected through trained 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 have an internal terminating resistance.

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.

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.
