摘要

#CMT# #/CMT# The method involves producing reference signals for a predetermined frequency break point, where the reference signals exhibit a period T. A device under test (DUT) (130) is supplied with the reference signal, and a measurement signal is received from the device under test supplied with the reference signal. Wave frequencies i.e. S-parameters, of the device under test is determined based on the measurement signal. The reference signal is formed by repetition of arbitrary time limitation signals e.g. chirp signal, in a specified range. #CMT# : #/CMT# Independent claims are also included for the following: (1) a computer readable medium has a set of instructions to perform a method for network analyzing a device under test (2) a measuring device i.e. network analyzer, comprising a reference signals producing unit. #CMT#USE : #/CMT# Method for analyzing i.e. network analyzing, a device under test (DUT) by a measuring device i.e. network analyzer (claimed) for measuring a wave frequency i.e. S-parameter. #CMT#ADVANTAGE : #/CMT# The method reduces the measuring period of the network analysis according to the measuring point within the bandwidth such that the resolution bandwidth is reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block representation of a network analyzer.'(Drawing includes non-English language text)' 110 : Source generator 120 : Bridge circuit 130 : Device under test 140-180 : Measurement signal producing units 190 : Digital signal processing device.
