The new 519-Teseq MD 4070, available from Westek Electronics , can be used as a passive or active RF current sensor in the frequency range of 10kHz to 400MHz (a model variation is available extending the frequency range to 600 MHz).
The 519-Teseq MD 4070 RF current sensor can also be used as a bulk current injector. RF current measurements are made in accordance with IEC/EN 61000-4-6, and BCI testing can be performed in accordance with ISO 11452-4, and various automotive standards including ISO 7637.
In the passive mode, insertion loss is typically 22 dB for a 50 ohm termination, in the frequency range of 100 kHz to 230 MHz. Transfer impedance is typically 4 ohm, whereas in the active mode the typical value is 160 ohm. Insertion loss is typically +10 dB.
The 519-Teseq MD 4070 RF current sensor can be used in conjunction with the NSG 4070 EMC immunity test system. Its features include substitution and closed loop test methods, making the system suitable for determining the immunity of electronic components used in passenger and commercial vehicles among automotive manufacturers including Ford, GM, Chrysler, Nissan, Renault and Peugeot.
