TEKBOX TBL05100-1C 5µH LISN
The TBL05100-1C is a 5µH line impedance stabilisation network (LISN) built for conducted emissions testing on high-current AC and DC supplies. It presents a defined impedance to the equipment under test (EUT), keeps noise from the power source out of the measurement and passes the EUT’s RF noise to a spectrum analyzer or EMI receiver through an N-female connector. As a top test equipment distributor, ELSYS recommends it for automotive, aerospace, defence and EV power electronics where currents reach 100 A.
DC resistance stays below 5 mΩ on both the Source+ to EUT+ and Source- to EUT- paths, so voltage drop and self-heating stay low under heavy load. The LISN handles up to 500 V AC at 50/60 Hz, 250 V AC at 400 Hz and 1000 V DC, with internal components rated to an absolute maximum of 1500 V DC. The TEKBOX datasheet includes a heat-up plot in chapter 8 for planning long runs at high current.

Where the TBL05100-1C fits
Use it for CISPR 25 component tests on EV traction inverters, DC-DC converters and battery management systems, for MIL-STD-461G and DO-160 conducted emissions setups on aircraft and defence electronics, and as the line network for ISO 7637-2 transient tests. Pair it with a Rigol spectrum analyzer from ELSYS for a full pre-compliance setup bought from one top test equipment distributor.
TEKBOX TBMDA-BCI100 Modulated Wideband Power Amplifier
The TBMDA-BCI100 is a modulated wideband RF power amplifier covering 1 MHz to 400 MHz with 52 dB typical small-signal gain. It is designed to drive bulk current injection (BCI) probes and other immunity transducers. Because modulation is built in, a plain CW signal generator is enough to create the required test signal, which is why ELSYS, as a top test equipment distributor, often suggests it to teams building their first in-house immunity bench.
Front-panel switches select CW operation, 1 kHz 80% AM, 1 kHz 50% duty-cycle pulse modulation, or 217 Hz 12.5% duty-cycle pulse modulation, the profile used to simulate GSM-type interference. VSWR monitoring with an Over VSWR indicator protects the amplifier when the load is mismatched. Gain flatness is 1.5 dB typical across the band at -3 dBm input, and the panel marks the RF output at +52 dBm maximum (about 158 W) from a 0 dBm maximum input.

Where the TBMDA-BCI100 fits
Typical uses include ISO 11452-4 BCI testing of automotive modules, conducted immunity pre-compliance on industrial controllers and general RF stimulus for component characterisation. It runs on 100–120 V AC or 200–240 V AC, draws 350 W at 220 V and operates from -20 °C to 50 °C, so it suits both lab benches and production test rooms. ELSYS, a top test equipment distributor and electronic test equipment supplier, can pair it with an RF signal generator to form a ready-to-run BCI source.

Conducted emissions and conducted immunity are two halves of the same test plan. The TBL05100-1C measures what your product puts back onto its power lines; the TBMDA-BCI100 checks whether it keeps working when RF energy is injected into its cables. Buying both from one top test equipment distributor gives you a single point of contact for compatibility questions, delivery and support.
