TEKBOX TBPS01 EMC Near Field Probe Set

Mike — Mon, 23 Nov 2020 05:11:56 +0000

The TEKBOX TBPS01 EMC Near Field Probe Set consists of H20, H10, H5 and E5 are magnetic field (H) and electric field (E) probes for radiated emissions EMC pre- compliance measurements. The probes are used in the near field of sources of electromagnetic radiation. They serve to locate and identify potential sources of interference within the building blocks of electronic assemblies.

The probes act similar as wide bandwidth antennas, picking up radiated emissions from components, PCB traces, housing openings or gaps and from any other parts that could be emitting RF. The probes are usually connected to a spectrum analyser. Scanning the probe over the surface of a PCB assembly or housing quickly identifies locations which emit electromagnetic radiation. By changing to a probe with smaller size, the origination of the emissions can be further narrowed down.

Additional applications are RF immunity tests by feeding a RF signal into the probe and radiating it into potentially susceptible circuit sections: Furthermore the probes can be used in the field of repair or debugging to track down issues in RF signal chains by contactless measurement of RF signal levels.

One more application is non- invasive measurement of RF building blocks such as modulators or oscillators. Frequency, phase noise and spectral components can be measured in conjunction with a low noise preamplifier. The TBWA2/20dB and TBWA2/40db wideband amplifiers are connected between EMC probe and Spectrum Analyzer to increase the dynamic range of the measurements.

TEKBOX TBOH01 5UH Line Impedance Stablisation Network – CISPR 25

TEKBOX TBOH01 5UH Line Impedance Stablisation Network

The Tekbox TBOH01 5µH LISN is a device required to setup conducted noise measurements of DC-powered devices.

It is designed to be used for EMC pre-testing in the frequency range of 150kHz to 110 MHz according to the CISPR-25 standard, ISO 7637-2, ISO11452-2/4/5 and with limitations DO-160/ED-14G.

The LISN is inserted into the supply line of the DUT (Device Under Test). Conducted noise which is present at the supply terminals of the DUT can be measured at the BNC connector using a spectrum analyzer or a measurement receiver. The source (supply) terminal and the DUT terminal are decoupled by a 5µH inductor.

Tekbox TBOH01 Specification

Frequency range: 100kHz – 110MHz (1GHz, see picture 4 in the manual)
DC Resistance: 40 mΩ
Maximum current: 10A
Nominal operating voltage range: 0 – 60V DC *

* The operating voltage range is limited to 60V DC for safety reasons. Though the component rating of the LISN is ≥ 200V, the positive supply voltage could accidentally be connected to the negative terminal of the LISN and thereby to the LISN housing. Under this circumstance, a DC voltage > 60V could cause a lethal electric shock when touching the housing.

TEKBOX TBLC08 5µH AC Line Impedance Stabilisation Network 8A

Mike — Thu, 19 Nov 2020 06:12:53 +0000

The TBLC08 is a Line Impedance Stabilization Network (LISN) for the measurement of line-conducted interference within the range of 9kHz to 30MHz, according to the CISPR16 standard. The device is designed for testing single phase, AC-powered equipment with supply voltages up to maximum 260V.

Conducted noise can be measured on the phase and on the neutral conductor. The TBLC08 is equipped with a switchable limiter/attenuator and an artificial hand connection.

Full compliance measurement of AC mains supplied products requires a high end set up consisting of an anechoic or screened chamber, a measurement receiver that complies with the requirements of CISPR 16, a 50µH LISN and a suitable table for the measurement setup.
