CA 2738716

The invention relates to a calibration substrate (100) having at least one calibration standard (12, 14, 16; 102, 104, 108) comprising at least two electrical connection points, each for one measurement gate (38, 42) of a vector network analyzer (40). According to the invention, at least one electrical connection point is formed of at least one calibration standard (12, 14, 16; 102, 104, 108) having a switch (20, 22, 24), wherein the switch (20, 22, 24) comprises a first electrical contact (30) electrically connected to an electrical connection point of the calibration standard (12, 14, 16; 102, 104, 108), a second electrical contact (32) designed for electrically connecting to a measurement gate (38, 42) of the vector network analyzer (40), and a third electrical contact (34), wherein the switch (20, 22, 24) is designed such that an electrical contact is established either between the first and third electrical contact (30, 34) or between the first and second electrical contact (30, 32).

Linvention concerne un substrat détalonnage (100) comportant au moins un étalon (12, 14, 16 ; 102, 104, 108) qui présente au moins deux points de raccordement électrique destinés chacun à un port de mesure (38, 42) dun analyseur de réseau vectoriel (40). Selon linvention, au moins un point de raccordement électrique dau moins un étalon (12, 14, 16 ; 102, 104, 108) est équipé dun commutateur (20, 22, 24), le commutateur (20, 22, 24) présentant un premier contact électrique (30) qui est connecté électriquement à un point de raccordement électrique de létalon (12, 14, 16 ; 102, 104, 108), un deuxième contact électrique (32) qui est réalisé pour être connecté électriquement à un port de mesure (38, 42) de lanalyseur de réseau vectoriel (40), et un troisième contact électrique (34). Le commutateur (20, 22, 24) est réalisé de telle manière quune connexion électrique est établie soit entre le premier et le troisième contact électrique (30, 34), soit entre le premier et le deuxième contact électrique (30, 32).
