Abstract: PROBLEM TO BE SOLVED: To widen a dynamic range when a transmission coefficient is measured. SOLUTION: This S parameter test set 20 includes five selector switches 21, 22, 23, 24, 25, three signal separators 26, 27, 28, and two test ports 30, 32. When a transmission coefficient S21 is measured, each connection condition of the switches 21 to 23 is set on the contact (a) side, and each connection condition of the switches 24, 25 is set on the contact (b) side. A signal outputted from a signal source 12 is inputted into a port 1 on one side of a measured device 40 through the test port 30 and the signal separator 26, and a signal outputted from a port 2 on the other side is led to a receiving circuit 14 through the changeover switch 24, a signal wire 36, and the changeover switch 25, and detected to measure the transmission coefficient S21.

Abstract: PROBLEM TO BE SOLVED: To verify an automatic calibration device and a measurement system at the time when a calibration is executed by providing a plurality of standards whose value is given in advance and a verification circuit whose value is given in advance. SOLUTION: First, four types of standards, an open circuit 31, a short- circuiting circuit 32, a load circuit 33, and a through circuit 34 whose value is given in advance are successively switched by switches SW2 and SW3, thus measuring each S parameter. A verification circuit 41 is a circuit for verifying the malfunction of an automatic calibration device itself and a measurement system. An automatic calibration device 40 is connected to a network analyzer 10 by cables 12 and 13 for automatically performing calibration and verification, thus verifying and calibrating the automatic calibration device itself and the measurement system and hence positively ensuring the measurement result of a device to be measured.

Abstract: PROBLEM TO BE SOLVED: To quickly inspect a surface of a substrate with a simple device. SOLUTION: A standard substrate 3 is faced symmetrically to a testing substrate 2 by a substrate arranging means 26 via an electrode member 4, then an RF electromagnetic wave is propagated to the member 4 by a network analyzer 5 to measure a characteristic, and the presence of defects in a surface of the testing substrate 2 is determined by a defective detecting means 25, based on a result measured hereinbefore. Since the surface condition of the substrate 2 is inspected based on a propagation characteristic of the RF electromagnetic wave, neither a device of large scale having complicated structure is not required nor long working time is not required.
