Die Erfindung betrifft einen vektoriellen Netzwerkanalysator, mit einer Eingangs- und Ausgangsmessvorrichtung (10, 20); einer Schwebungsquelle (40) zum Erzeugen eines optischen Schwebungssignals; einer optischen Übertragungsvorrichtung (50), die das optische Schwebungssignal in mindestens ein erstes und ein zweites Teilsignal (TS1, TS2) aufteilt, wobei die Übertragungsvorrichtung (50) das erste Teilsignal (TS1) an zumindest einen Terahertz-Sender (11, 21) und das zweite Teilsignal (TS2) an zumindest einen Terahertz-Empfänger (12, 22) und/oder zumindest einen Terahertz-Referenzempfänger (13, 23) leitet; sowie einer Phasenveränderungseinheit (60) zum Variieren der Phase des ersten und/oder des zweiten Teilsignals (TS1, TS2) des optischen Schwebungssignals.
(EN)
The invention relates to a vector network analyzer comprising: an input- and output measuring device (10, 20); a beat source (40) for generating an optical beat signal; an optical transmission device (50) that divides the optical beat signal into at least one first and one second partial signal (TS1, TS2), wherein the transmission device (50) conducts the first partial signal (TS1) to at least one terahertz transmitter (11, 21) and the second partial signal (TS2) to at least one terahertz receiver (12, 22) and/or to at least one terahertz reference receiver (13, 23); and a phase changing unit (60) for varying the phase of the first and/or the second partial signal (TS1, TS2) of the optical beat signal.
