Tekbox TBOH01 LISN

Ideal for EMC pre-compliance testing to CISPR 25 – The TEKBOX TBOH01 is a 5µH DC LISN (Line Impedance Stabilisation Network) for the measurement of conducted emissions, across the range 150kHz to 110MHz, from DC powered devices.

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 analyser or a measurement receiver. The source (supply) terminal and the DUT terminal are decoupled by a 5µH inductor.

  • Frequency Range: 100kHz to 110MHz (1GHz see figure)
  • DC Resistance: 35mΩ
  • Maximum Current: 10A
  • Maximum Source Voltage: 60V

For use up to 60V DC maximum only. First line suppressor included and Telonic always recommends you source your own additional protection suited for your particular application. (As in all EMC tests, make sure you measure your worst case transients before connecting any analyser to your LISN and have to hand easy-add-on attenuators and conducted emissions EMC transient limiter protectors, as is good practice with any sensitive modern spectrum analysers or receivers).



User Manual

Tekbox TBOH01 User Manual


Frequency range 100 kHz – 110 MHz
DC Resistance 40 mΩ
Maximum current 10A
Nominal operating voltage range 0 – 60V DC
Absolute maximum rating 200V
Built in surge protection
Terminals suitable to clamp external source capacitors

* 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.
