The TBL5032-3 is a line impedance stabilization network for measuring line-conducted disturbances in the range 9 kHz to 30 MHz, according to the CISPR 16-1-2 standard. The unit is designed to test 3-phase and single-phase, AC-powered equipment with supply voltages up to a maximum of 450V/260V and 32A. Line noise can be measured on each phase and on the neutral conductor.
The TBL5032-3 has separate RF outputs for each phase and neutral and can therefore be connected to the TBLM1 to split the emissions into its common mode and differential mode components. The TBL5032-3 has no built-in high-pass filter at the RF outputs, but instead comes with an external 9 kHz coaxial high-pass filter.
The single-phase DUT socket is available in country-specific variants.
