EMC-STPL Stripline 50/90 Ohm DC-1GHz
The EMC-STPL striplines are designed for automotive immunity testing of components according to the standards ISO 11452-5 and SAE J1113-23. Striplines are a variation of TEM lines which allow an application of electromagnetic fields with a good homogeneity in the test volume.
The stripline is fixed on a table and it is easy to move. It is assembled on 2 joined table with foldable legs in order to reduce the occupied space when storage or during the transport. It is the only stripline on the market able to carry out test up to 1 GHz with excellent return loss. Manufactured in hot galvanized steel and aluminum with Alodine treatment and Teflon dielectric supports. The striplines are available with 50 Ohm or 90 Ohm impedance.
